Connecting to another phone's camera. How to make an IP surveillance camera from an Android smartphone

Useful tips

If, by coincidence, you are tormented by suspicions about what is happening in your absence (for example, a child or pet is alone at home, an apartment is unattended), there is an option to control the situation from a distance using a camera.

The Internet portal ru.ivideon.com optimally implements the ability to remotely connect from any device to web cameras, IP cameras and analog cameras. On the “Tariffs” tab you can familiarize yourself with the characteristics possible options connect the service and select the appropriate one. Click on the “Add camera or DVR” button, select the appropriate type of camera to connect, read the instructions in the next step and click “Continue”. Now you need to download and install the program on the computer to which the camera is connected; to do this, select your operating system. Will begin standard installation, simply select your language and follow the installation wizard. The setup wizard will start automatically. Click “Next”, then enter your e-mail that you specified during registration, and select the camera location from the list. This formality is created for your convenience (if the list of cameras is large, these groups will be easier to navigate). Make sure your camera is connected and working properly, click “Next”. If active cameras are detected, you will see a list of them, otherwise try to “reconnect” the working camera again and click “Repeat search”, if everything went well - “Next”. If you want the video to be saved in the archive, check the “Include in archive recording” checkbox; if you are only interested in online broadcasting of images from cameras, uncheck it. To prevent the program from starting automatically when you turn on the computer, uncheck the “Start Ivideon Server when the OS starts” checkbox, and then click “Finish”. If the “Log in to your Personal Account” checkbox remains active (by default), your page on the website ru.ivideon.com will automatically open in the browser. In the list on the right, select the active camera, marked in green, and you will immediately see the live broadcast. To make it more convenient for you to watch videos from your tablet, phone, laptop or other computer, you can download the application. To do this, either add to your wishlist and install the Ivideon application, as shown in the screenshot, or exit the gadget to “google play” and find it through the search bar. The second way to observe the situation is with using Skype. Create in the program, add this one on Skype. On the computer to which the camera is connected, log into Skype under this account, in the video settings, in the “Automatically receive video and share the screen for” field, select “only people from my contact list.” Now in the menu on the left, activate the “Calls” item, click on the “Open additional settings” button located in the window on the right. Select “Only from my contacts” in the “Receive calls” field and check the remaining boxes so that the video broadcast will automatically start as soon as you call your additional account. Advanced users also offer the following option: install a terminal server on the computer with the camera (to spy on it unnoticed, i.e. if someone is working on the computer, so that they don’t get kicked out), connect the Remote Desktop Protocol (RDP) and use any program that works with the camera. An indicative list of programs is available on web-kamera.ru. However, no one bears responsibility for the possible maliciousness of the programs. Therefore, be vigilant, check sites on the online service trustvset.rf and do not neglect antivirus software.

The described methods of connecting to remote video cameras are legal, but keep in mind that interfering in someone else's personal life may not bring the expected result. Act solely for your own peace of mind and for the benefit of others.

Firstly, I’ll note as an educational opportunity that an IP camera allows you to connect remotely from another computer to a smartphone camera and even record everything on video. Surprisingly, similar cameras cost in markets from about $50 (more or less high quality model). But we always want to save money, and therefore we can even make a normal IP security camera from an old unnecessary Android smartphone. You just need to install special application and you will have a simple security camera in your hands. In the same way, you can make a baby monitor out of your phone.

So without further ado, let's move on to the instructions. You will need an IP Webcam – free application, which can be downloaded from the Google Play store. To work you only need Wi-Fi internet.

The best choice

IP Webcam works better if you are not connected to the mobile Internet, but to Wi-Fi networks. All this is because the majority mobile operators set restrictions on some IPs, including the IP Webcam service. So make sure you are connected to available Wi-Fi Internet. After installing the application and connecting, all computers, smartphones and phones within the same network will have access to the video through a web browser.

IP Webcam setup:

If you are far from home...

Technically, the IP Webcam service must be accessible from another network - via the Internet. However, this requires more in-depth knowledge of the network configuration - that is, the average user can configure the connection on their own, but everything often depends on the Internet provider, as well as the router in your home. The good news here is that there is a very simple solution - use Chrome Remote Desktop(or other popular app for remote access – TeamViewer). Using the Google service, you can log in to your home computer and view webcam video through a web browser. In fact, this method is quite convenient and the video runs quite smoothly. The disadvantage of this method is the need permanent job home computer.

Additional tips:

If you are going to often view video using IP Webcam through your smartphone camera, we recommend purchasing a wide-angle lens for it. This will give you a wide viewing angle in tight spaces.
If you know how to access the router settings, then it is better to find a way to assign a permanent IP address to your smartphone, which will work as a camera. This way you can look into your home at any time from anywhere.
can't connect? Apparently your firewall or router interfered with your plans. The problem can be anything, but it can often be cured by whitelisting the IP address of the smartphone with the IP Webcam.
You may want to add motion detection capabilities to your smartphone security camera so that it automatically starts recording. This option is also possible, just look at the IP Webcam settings.

You can’t even imagine how easy it is to end up in the image Big Brother and watch through the camera the actions of any person. Of course, if there is a “webka” next to him. To do this, you need to know the IP address of the “enemy” laptop and have access to special programs.

How to connect to someone else's webcam: methods

Download onto your computer one of the programs designed specifically for these purposes: espionage using the web. For example, Remote Administration Tool or Remcam. Both are freely available on the Internet. In some cases, you will be asked to enter your mobile phone number to download them.
Watch videos on how to connect to someone else's camera recorded on YouTube. Hackers will do this before your eyes with precise descriptions and instructions in a maximum of 5 minutes. Usually, to be able to connect, they suggest: asking Google with the subject: inurl:MultiCameraFrame?Mode=, in the list that opens, select the required URL and camera...motor...recording! In our case - surveillance.

For those who do not have enough specific information, they can additionally look for advice from professionals (large-scale hackers) on specialized forums. For example, on the pages of the Internet magazine “Hacker”.

However, before you start spying, remember: intruding into a person’s personal space using a webcam is a criminal offense. For example, in America, a real judicial scandal broke out when it turned out that the students of one of the schools were being spied on by the system administrators of the educational institution through web cameras installed on the children’s laptops.

Today we will talk about how to independently connect to the webcam of another computer via the Internet. We will also consider methods and programs remote connection to webcams of PCs, laptops, tablets and phones

Advanced users also suggest the following option: install a terminal server on the computer with the camera (to spy on it unnoticed, i.e. if someone is working on the computer so that they don’t get kicked out), connect the Remote Desktop Protocol (RDP) and use any program that works with the camera. An indicative list of programs is available on web-kamera.ru. However, no one bears responsibility for the possible maliciousness of the programs. Therefore, be vigilant, check sites on the online service trustvset.rf and do not neglect antivirus software.

A way to secretly monitor the situation through someone else's webcam is using Skype. Create in the program new account, add this contact to your Skype list. On the computer to which the camera is connected, log into Skype under this account, in the video settings, in the “Automatically receive video and share the screen for” field, select “only people from my contact list.”

To make it more convenient for you to watch videos from your tablet, phone, laptop or other computer, you can download the application. To do this, either add to your wishlist and install the Ivideon application, as shown in the screenshot, or exit the gadget to “google play” and find it through the search bar.

iSpy is an updated version of a specialized tool that is very lightweight and not difficult to use, its main purpose is to monitor premises, for these tasks either web cameras or a regular microphone are used, or you can do all of them at once and second. The idea is simple, you connect the camera to your computer, launch the development, it instantly intercepts the image from it and displays it on the monitor, any movement in the camera’s field of action will be recorded on HDD, then you can view the records.

In addition, iSpy allows you to view live (real-time) or stored videos via the Internet or mobile devices. All data is compressed and saved in the format flash video. It is possible to work on several computers simultaneously, as well as control the program remotely, protect it with a password, create groups or join existing groups (on the developer’s website) and give group members access to your web cameras and microphones

How to independently connect to a remote webcam via the Internet on other computers, video surveillance systems and smartphones. Methods and programs for remotely controlling webcams on a network and viewing through a remote someone else’s webcam. Sometimes users of personal computers of various classes may need to remotely connect to a webcam. The reason for this may be the desire to observe a certain point where the camera is installed and, accordingly, be aware of what is happening there.

Articles on the topic "How to connect to a remote webcam" How to set up a webcam How to turn on the webcam on a laptop How to take photos with a laptop camera

First of all, in order to connect to the webcam and view videos or photos, you need to create a connection via local network. To do this you need to have a switch, i.e. special network switch, which allows you to create multiple connections at once, and at least two Ethernet cables. After this, connect all devices using Ethernet cables.

Now, using the installation program that is usually included in the initial package, determine the IP address for the camera. You will enter it in address bar browser or other program. It is best to create a static IP address, as this is much more convenient for work. Then you need to open an Internet browser and type the IP address in the address bar. If you are using a modern browser, then no software will be downloaded, as it necessarily supports video streams.

This is how you connect a webcam to a computer, but if you want to connect to a camera located at a very long distance, then for this you need special programs, for example, WebCam Monitor 4.20 or Webcam Surveyor 1.7.0, in which you also need indicate the IP address and some other data. The process of setting up programs of this kind is extremely simple, since you only have to answer questions. But, despite their simplicity, they offer many important advantages, since you will be able to detect illegal entry into your home or other troubles in time. As you can see, connecting remotely to a webcam is not so difficult, and thanks to this you can always be aware of what is happening in the observed area.

To observe events taking place in a certain place, you need to have a camera installed there, connected to the Internet and Personal Computer, from which you could control it. By connecting to it, you will see everything that happens in real time.

You will need

Network switch.

Create a local network connection to connect to the remote camera. To do this, you will need a special network switch. It is needed in order to create several connections at once. Take two Ethernet cables and connect all your devices.

Use the installation program. As a rule, it is included in the basic package. If not, then download it from the Internet and install it on your personal computer. Using this program, determine the IP address of the remote camera. Subsequently, you will enter it into the address bar of your browser or any other program convenient for you.

Create a static IP address so that later you can special problems turn on the camera remotely. Open your browser. Enter the IP address of the camera in the address bar. Use modern browsers, supporting video streams so as not to resort to the use of additional software. .

Use special programs if you want to connect to a camera located at a fairly large distance from you. To use remote camera install WebCam Monitor 4.20 or WebCam Survevor 1.7.0 on your personal computer. Using this program, indicate the IP address of the camera you are interested in. What follows is a fairly simple setup procedure. You will only need to answer the questions that the program will ask.

The function of viewing a webcam via the Internet will help you always be aware of events both at home and at work. Remote online viewing will allow you not to worry about the baby, check the child’s perseverance while completing school assignments, and monitor the work activities of employees. Using a remote access program, you can always check whether your household is safe, their well-being, and the nuances of how your family spends time during rest or work. Of course, your employees should be notified about the possibility of monitoring.

Setting up a function in the remote access program

To be able to view webcams over the Internet, you need to connect the program to your account in the settings. Click the "Settings" button in the main program window, then select "View via Internet" and enter your NeoSpy account login and password. Connecting the program to an Internet account is similar to that described in the article “Viewing the screen via the Internet”. No additional configuration required.

Viewing pictures via the Internet

For remote viewing cameras via the Internet, you should go to the website https://ru.neospy.net and log in to your account.

After this, you should open the “Your computers” menu and click on the selected computer. In the "Image sources" field, select your webcam or the "default webcam" item. After that, click the "Connect" button.

Do not forget that when using a webcam as a source of images for a remote access program, it will become inaccessible to others for the duration of the shooting. user programs(for example, for Skype).

If your computer is already turned off or you want to view your photo history for the day, click

“View history”, then after selecting the required date and time for generating the report, click on the “View actions” link.

As a result, a report viewing window will open, in which you can go to the “Webcams” tab and view images for the desired period.

Inclusion local save pictures e

Sometimes you need to save pictures to your local computer instead of viewing them over the Internet.

Let's take a closer look at how you can enable saving pictures from webcams to your local computer, in addition to Internet viewing.

The first method is if you have access to a PC

Standard method activating the webcam settings through the NeoSpy program is described in detail in the article “Tracking via a webcam”.

The second way to set up is through an online account

To set up viewing webcams via the Internet, you need to log into your Internet account on the official website and go to the “Your computers” page

Then, click on the desired computer in order to see full information

To configure the function, click on the “Manage program settings” link. After this, the settings page will open (Fig. 3) on which you will be prompted to obtain program settings. Please note that in order for all changes to take effect and you to be able to open the program, you must have administrator rights.

After clicking on the “Get program settings” button, you should wait (from 10 to 30 seconds). During this time, the remote access program will download the settings. In this case, two mandatory nuances should be taken into account: the first - on the “Your Computers” web page, the required computer must have the data collection function activated (the function is enabled by default), the second - spyware NeoSpy must be running in hidden mode. As a result, the settings will be loaded as text commands

In our case, the required line of code responsible for the function of viewing webcams via the Internet: “...WebCam=1;...”. The line is located in the (Tracking Settings) section. In this case, the program saves pictures from the webcam, but if the value is “...WebCam=0;...”, the pictures are not saved. The designation and functionality of the remaining lines can be studied by clicking on the link and reading the article “ Remote installation spy." After any changes, do not forget to save them by clicking on the “Apply settings” button located at the bottom of the website. s.

If installed program is not Russified, download the Russifier, or use a translator to correctly configure the software. After this, you will be able to use the remote webcam, if this use is legal and the administrator of the computer to which this camera is connected will grant you the appropriate rights.

The setup wizard will start automatically. Click “Next”, then enter your e-mail that you specified during registration and select the camera location from the list. This formality is created for your convenience (if the list of cameras is large, these groups will be easier to navigate). Make sure your camera is connected and working properly, click “Next”. If active cameras are detected, you will see a list of them, otherwise try to “reconnect” the working camera again and click “Repeat search”, if everything went well - “Next”. If you want the video to be saved in the archive, check the “Include in archive recording” checkbox; if you are only interested in online broadcasting of images from cameras, uncheck it. To prevent the program from starting automatically when you turn on the computer, uncheck “Start Ivideon Server when the OS starts,” and then click “Finish.”

The second way to monitor the situation is using Skype. Create a new account in the program, add this contact to your list on Skype. On the computer to which the camera is connected, log into Skype under this account, in the video settings, in the “Automatically receive video and share the screen for” field, select “only people from my contact list.” Power supply for IP video cameras can be organized as follows: using separately installed power supplies, and using video cameras that support the PoE standard.

Network equipment that supplies power to video cameras using the PoE standard is divided into classes based on the amount of power supplied (Table 3).

To increase the length of the interval from the IP video camera to the switch, PoE injectors are used.

PoE injectors are designed to power IP video cameras via standard cable UTP Cat.5e or 6 at speeds no more than 10/100 Mbit/s. Gigabit networks do not have the ability to use PoE power mode.

NETWORK HARDWARE

Network equipment - devices that make up the network that connects information flows from IP video cameras.

There are two types of network equipment:

■ Active network hardware- equipment that is capable of processing or converting information transmitted over the network. Such equipment includes network cards, switches, routers.

■ Passive network equipment - equipment used to transmit signals at the physical level. This network cables, connectors, repeaters and signal amplifiers. The main elements of active equipment used to build a network are switches and routers.

❖ SWITCH

One of important characteristics switch - number of ports. This determines how many network devices can be connected to it.

To determine which maximum speed can provide one switch port, you need to find the “switch fabric bandwidth” parameter, say 32 Gbps, and divide it by the number of ports (16) multiplied by 2. For example: 32 / (2 x 16) = 1 Gbps .

Now in the menu on the left, activate the “Calls” item, click on the “Open additional settings” button located in the window on the right. In the “Receive calls” field, select “only from my contacts” and check the remaining boxes so that the video broadcast will automatically start as soon as you call your additional account. Advanced users also suggest the following option: install a terminal server on the computer with the camera (to peep unnoticed, i.e. if someone is working on the computer, so as not to be “thrown out”), connect the Remote Desktop Protocol (RDP) and use any program that works with the camera. .

The simplest option for using “IP Webcam” from a computer is as follows: launch the browser and enter the IP address and port of the device in the address field. For example, on my home Wi-Fi network, the link looked like this: “http://192.168.4.6:8080/”, where 192.168.4.6 is the phone’s IP address, displayed on the display of the mobile device after starting the broadcast.

Possible ways viewing the broadcast several times. The simplest is to use a computer browser. While testing the application on my computer, it turned out that allowing the JAVA plugin to run was sufficient. Moreover, in the future you can allow this plugin to run without additional requests. If the plugin is missing, you can download it from the hyperlink displayed on the “Smartphone Camera Service” page. It also contains the settings necessary for watching video and listening to audio in any third-party application. The resulting network topology is presented in Figure 8. We see that with the estimated load created by video cameras on one port, 8.14 Mbit/s real circuit allowed us to get exactly the same flow on one port - 8.14 Mbit/s.

In the considered example, ports for connecting servers, NAS drives and workstations of video surveillance post employees were not taken into account.

DEVELOPMENT OF PHYSICAL NETWORK TOPOLOGY

The physical topology of the network is strictly connected with the installation locations of video cameras and the routes for laying cable communications to the server room or monitor security post. In this regard, the physical topology of the network begins to be designed using a floor plan or a site plan, where the installation locations of video cameras are indicated.

The main problems that arise in the process of developing a physical topology are the following:

■ The length from the camera to the switch exceeds valid values distances of 80-100 meters.

■ PoE power is limited long distances or the network does not support PoE.

If the length from the camera to the switch is more than 80-100 meters, first of all, you need to try to group the cameras according to the principle of the minimum distance to the active equipment locations or move the active equipment to another place, closer to the video cameras.

If it is impossible to solve a problem in this way, you need to use special devices, allowing you to increase the distance from the camera to the active equipment. Depending on the distance over which you want to increase the signal transmission, you can use fiber optic cable inserts and RF shielded cable inserts.

One of the viewing options is using a video player that supports video streaming, for example, the one recommended by the authors of the application free player VLC. Moreover, everything is quite automated - when you click on the “view in external player” hyperlink, an m3u file will be downloaded to your computer, which can simply be opened with the player.

To connect an IP camera to Skype or other applications that work with web cameras, you will need to install the appropriate drivers on your computer. This operation is described in sufficient detail on the page “Connect to a Windows computer for use with video chats” (the link to it is on home page"Smartphone camera service"). I would like to note that everything actually works quite correctly, but for compatibility with Skype 5.x I had to install the “IP Camera Adapter”. Also, using the appropriate links in the web interface, you can take a full-size photo and upload the current video frame as a picture. Interesting feature“tinyCam Monitor” - viewing pictures from random public cameras. And it is convenient enough to evaluate the capabilities of the application. To configure the web cameras used, click the “Settings” button. Cameras" in the main program dialog box and select the desired camera. To change camera settings, press the button with a pencil icon located next to its name. Through "tinyCam Monitor" you can view both cameras from open access, and requiring authorization using a login and password.

In the settings for recording images from the camera (available in the paid version) to a memory card, ftp or cloud services, you can set the frame rate and limit the maximum amount of space occupied (for an SD card). Another one useful feature pro versions – the ability to scan cameras available on the network. Recommendations for setting up “tinyCam Monitor” for using a software web camera created using “IP Webcam” are given on the start page of the web interface of the software camera. Consider an example of building an information network topology for 49 IP video cameras with a frame size of 1920x1080:

■ Set the frame rate and codecs used for each camera. Frame rate - 24 fps. Codec - H.264. We will assume that the selected parameters are the same for all cameras.

■ From Table 1 we find that for the given parameters the flow rate from one camera is 6.51 Mbit/s.

■ The total stream from 49 video cameras is 49 x 6.51 = 318.99 Mbit/s. Taking into account a 25% margin for unforeseen changes in traffic intensity in front of the video cameras, the total flow is 318.99 x 1.25 = 398.74 Mbit/s.

■ The switch port to which the video camera is connected must provide a flow rate of at least 398.74 Mbit/s / 49 = 8.14 Mbit/s.

■ We build the network on cable twisted pair UTP Cat.6 type with a maximum speed of 1000 Mbit/s. Taking into account 80% of the network load from the maximum value, the permissible flow is 1000 Mbit/s 0.8 = 800 Mbit/s. The total stream from all cameras (398.74 Mbps) does not exceed the maximum speed in the UTP Cat.6 cable (800 Mbps). Therefore, the video surveillance system will work in one physical network without creating additional subnets.

What is important is that the Ivideon service is free for personal use, and the minimum configuration required to work with it is a computer with Internet access, installed application“Ivideon Server” and a web camera connected to it. Moreover, the service developers offer branded IP cameras, where Ivideon support is integrated into the software. Limitation free version service - 1 video server “Ivideon Server” with two connected cameras or 1 IP camera. A static external IP address is not required to use the service.

Registration with Ivideon is quite simple - just enter your email address and enter the desired password to access personal account. After registration, the required instance of “Ivideon Server” (or an IP camera that supports the service) is “linked” to your personal account. At this point, the setup is complete and you can proceed to viewing the recording, and even the archive is recorded on the Ivideon servers.

The scope of mobile Internet use is becoming wider. At the dawn of an era mobile access its capabilities to the network were limited to working with email and wap sites, and the ability to view regular HTML sites from a mobile device seemed like a real breakthrough. Over the past time, the Internet on mobile devices has become faster and more accessible, so now you won’t surprise anyone with Internet radio or an online cinema with a huge catalog of legal videos.

The popularization of the use of mobile devices to work with IP cameras or in their role is not at all surprising - with a fast Internet channel (we are still talking, most often, about Wi-Fi), organizing a video broadcast from a mobile device is quite simple. However, as well as making a smartphone or tablet part of a video surveillance system that allows you to view what is happening in your home, country house or office from anywhere in the world. And it's really convenient. And as 4G networks develop, the popularity of this use of smartphones will only grow.

It all started in one of the computer laboratories in Cambridge back in the early 90s of the last century, when the Global Wide Web was just beginning its victorious march across the planet. A group of scientists, about 15-20 people, worked on a project in the field network technologies. The working conditions were spartan - there was only one coffee maker for the entire team, which could not meet the needs of the entire team. The main work was carried out in the laboratory; the staff lived in the same building, but in a different part of it. To spur their thinking process with a cup of invigorating drink, participants in the scientific project were forced to frequently visit the corridor located on the floor above, where the coffee maker was located. Often such trips failed, since some colleagues had already managed to empty the coveted container. The situation required non-standard solution, and it was found.

One of the computers in the laboratory had a frame grabber. A camera was connected to it, which was aimed at the object of observation. The same computer played the role of an IP server using specially written software. Those who wanted to know whether there was coffee had to run client software on their computer that connected to the server. As a result, on the remote computer in a small window it was displayed black and white image, updated three times a minute. A note about this interesting complex was published in Comm-Week magazine on January 27, 1992. Not much time has passed since the appearance of the first prototypes of IP cameras, but they have already become a fully formed separate class devices that make everyday life easier, more convenient and more fun.

How does an IP camera work?

It consists primarily of a sensor.
Very often, instead of standard CCD matrices, cheaper CMOS sensors are used for video surveillance. Although they have lower sensitivity and are not very good color rendition, their use makes it possible to greatly reduce the cost of the device, since these sensors are “all in one chip” with a digital data output.
Next: the network camera includes a microprocessor for video compression and motion detection (or simply a compressor chip). The most popular is JPEG, as it is the simplest and cheapest; MPEG4 is also used quite often, MPEG2 is the rarest and most expensive. With the expiration of the arithmetic encoding patent, WaveLet gains popularity. Finally, the network camera includes Network Controller 10/100 Mbit/s.

Design and principle of operation of the IP camera:

A modern IP camera is digital device, which produces video recording, digitization, compression and transmission of video images over a computer network. Therefore, the IP camera includes the following components:
- CCD matrix
- lens
- optical filter
- video capture card
- video compression unit
- central processor and built-in IP server
- RAM
- flash memory
- network interface
- serial ports
- alarm inputs/outputs
As a photodetector, most IP cameras use a CCD matrix (CCD - charge-coupled device) - a rectangular light-sensitive semiconductor plate with an aspect ratio of 3: 4, which converts the light incident on it into an electrical signal. The CCD matrix consists of large number photosensitive cells. In order to increase the light sensitivity of a CCD matrix, a structure is often formed that creates a microlens in front of each of the cells. IN technical parameters IP cameras typically specify the CCD format (diagonal length of the sensor in inches), the number of effective pixels, the scan type (interlaced or interlaced), and sensitivity. A typical IP camera contains a lens, optical filter, CCD, circuitry digital processing images, an image compression scheme, and an IP server for connecting to the network. Each network video camera has its own IP address, computing functions, and built-in software, allowing it to function as an IP server, FTP server, FTP client and an email client. Most modern network cameras also include many other attractive features such as motion detection, alarm input/output and e-mail support.

You will need certain software and you will not have the ability to administer remotely.

Stability

The camera works without any additional components, giving greater stability.

In addition to the camera, its stability also depends on the stability of the computer and software.

Quality

High quality when using MJPEG.

Components are not used High Quality, hence the small resolution.

Price

The cost of a network camera is just the cost of a network camera.

Cost of solution = Total cost of camera + computer + software.

How to connect an IP camera over a local network.

You will need the following components: a computer, a switch, a network camera and an Ethernet local network. There are also wireless options

Example of organizing video surveillance in an Office behind the front door

Step 1: Identify your needs

Do you only want to use the camera indoors? Or for outdoor use?

Do you want a fixed-angle camera or a variable-angle camera that allows you to pan, tilt or zoom remotely?

Will you need additional options, such as motion detection, alarm notification, camera power via Ethernet, audio?

Do you want to simply observe or also record what is happening?

Do you need camera protection from external influence?

Determine how many cameras you will need for your needs.

Step 2: System requirements

If your building does not yet have a local network installed, which allows you to simply connect the network camera to the network output, then you will need the following equipment:

A switch that will serve as the central connection point between your network camera and your local computer

By at least two Ethernet cables: one to connect your network camera with a switch and the other to connect your local computer with a switch.

Step 3: Installation.

Connect all devices to each other via a switcher

Step 4: Assign an IP address to the network camera.

You must assign an IP address to your network camera so that you can access it through an IP browser on your local computer. You can choose between automatic and static IP address. A static IP address is recommended because you won't have to look up the camera's IP address every time.

To set the IP address of the network camera. You can use the software that is on the CD that comes with the product, or can be downloaded from the manufacturer's website or using the IP address protocol or ping utility. In any case, you will find all the information in the installation manual for the network camera.

Step 5: Finish the network camera installation.

Once the IP address has been assigned, you can open the IP browser on your local computer and enter the IP address of the network camera in the address field. For new visitors with an IP browser Internet Explorer, the browser will ask if you want to download a camera program. This program is a must watch operational video from a video server or video camera. It also provides control of MPEG-2, MPEG-4 formats, audio streams, motion detection and pan/tilt/zoom in the browser window. (Other IP browsers may have native support video streams and do not require installation of additional components.)

Click the "Yes" button to install the program

How to access an IP camera over the Internet

Example: After you have already received an image from an IP camera on your computer, you decide that it would be nice to be able to access the camera wherever there is Internet. For example, as a store owner, you want to control the activities in the store from your home, instead of having to be present every minute at the workplace

Step 1: System Requirements

Scenario A)

If your building (where the camera should be located) is already connected via Ethernet to an ISP (internet service provider), simply configure account, connect the network camera to the switch via the network output, and you should get a dynamically assigned public IP address for the network camera. Follow the installation commands for the network camera. Special software or utility for the IP camera will be useful in identifying the IP address.

Since the assigned IP address may be changed by your ISP (due to the limited supply of IP addresses shared among its clients), see Step 4 below to find out how you can assign cameras to a specific IP address.

Scenario B)

If your building is not equipped with Ethernet access, then in most cases you may need following devices:

Broadband modem for asymmetrical digital subscriber line connection (usually supplied by your Internet service provider), or cable TV

Broadband Router, which may also be called an Internet Gateway, (A Broadband Router allows local network users to share a single Internet connection. It also serves as an interface between the Internet, the ISP and the Local Network.)

A switch that allows various devices from the network communicate directly with each other and allows devices from the local network to have separate IP addresses),

NOTE: Most broadband routers have a built-in SWITCHER function, so separate equipment not required

Network camera

Local computer

Computer for remote monitoring

Step 2: Assign an IP address to your camera p.

Since a broadband router typically assigns automatic, local IP addresses to devices on the local network, such IP addresses are subject to change. A static (permanent) IP address is recommended for the network camera. To assign a static IP address, find out the router's IP address range, which, for example, could be from 192.168.0.2 to 192.168.0.35. If you choose to use an out-of-range IP address, such as 192.168.0.100, as a static IP address for the camera, it is likely that you will not risk your device having conflicts with other devices that receive automatic addresses.

Setting the IP address for your camera can be done in three ways: different ways, as stated in the camera manual. Once the IP address is assigned, set the subnet, and gateway (this information can be obtained from the router), and configure the camera settings: password, registered users to ensure access restrictions to the camera.

Step 3: Port Forwarding

The broadband router, as mentioned earlier, provides the interface between the Internet, the ISP and the Local Network. The router obtains an external IP address from the Internet service provider and supplies internal (local) IP addresses to devices on the local network.

To access a network camera that resides on a local network, you must identify the external IP address of your router (see your router's manual), and configure your router so that the external IP address is directed to the static, local IP address of the network camera . This process is called opening a port; that is, when you print the router's external IP address from any network computer The Internet locates your router, in turn forwarding your request to the local IP address that is assigned to the network camera.

Launch an IP browser and log into the router's built-in IP pages via Login to Router Configuration Pages.

Find the menu item "port forwarding" (or similar), with a table approximately as shown below:

Service name

Start port

End port

Server IP address

Not configured

HTTP (Network)

Since the camera sends its video over HTTP, you must configure the HTTP service like this:

Service name

Start port

End port

Server IP address

Not configured

HTTP (Network)

Unofficial port

192.168.0.10x

Save the configuration to the router and exit the configuration pages. The configuration is complete. Any requests reaching the router's external IP address on port 80 will now be sent to the camera's IP address: 192.168.0.100.

If you want to make more than one network camera accessible via the Internet, then you must use additional (unofficial) router ports, such as 80xx, and associate them with the network address of the IP camera.

Step 4: What can you do if your ISP frequently changes Dfi external IP address

Create an account in the DNS service that serves and registers domain names (for example www.nic.ru, etc.) and bind it to an external IP address. A domain name, such as www.IP-kamera.ru, is clear to the user, easy to remember, and you can assign each domain its own network device, i.e. its IP address. Whenever the router's IP address changes, it will be automatically logged DNS service, in order to update your IP address so that you can access your network camera using the same address. With

Most broadband routers have native DNS support, such as www.dyndns.org.

Another alternative: You can buy or rent a static external IP address from your Internet service provider.

How to build a security system using IP cameras.

An effective way to expand security systems in a building, factory, hospital or university campus is to use existing infrastructure:

During the day, guards watch a monitor in the control room

At night and on weekends, monitoring can be performed remotely at a central monitoring station serving several companies

Built-in motion detector can trigger an alarm and start recording the alarm event

In the event of an alarm, the security manager can view the images on the computer closest to him or remotely via an Internet connection.

The images may be stored on a computer at the enterprise or on the server of the Internet service provider (ISP). Storing images in remote locations eliminates the risk of an attacker destroying evidence of crimes.

Cameras can also send images automatically to the host computer, or main computer itself can search for images from cameras. If the host computer has Windows system, you can use a special software, designed for network cameras. The program can display a picture in real time or work with archives. When the storage period for video images reaches, for example, two weeks, the program automatically erases them.

tinyCam Monitor

In addition to turning your smartphone into an IP camera, it can also be used to view images from existing cameras. In particular, the developers of the “IP Webcam” discussed above suggest using the “tinyCam Monitor” program, which exists in free and paid (about 125 rubles) versions. The functionality of this application includes:
Support for M-JPEG IP cameras/video servers and webcams from all well-known manufacturers, incl. Axis, FOSCAM, D-Link, Edimax, Panasonic, Pixord, TRENDnet, Mobotix, Vivotek, Beward. Full list available on the official website;

Greetings to all readers!
Smartphone thefts have become commonplace these days. But what’s more saddening is not that it could be stolen, but that the police are up to similar problems no one is of any interest - such cases are almost never solved, so most often a criminal case is not even opened. Therefore, we again have to rely only on our own strength. Today we will find out how you can organize remote access to smartphone or a tablet based on Android OS using certain programs and services to monitor your phone.

How to track the location of a phone?

Today we’ll play a little secret agent and install certain software into our smartphone, with which we can do a little spying on the phone and its owner. Yes, yes, for smartphones and tablets running the Android system, as well as for the iPhone, there are applications with which via wifi you can not only work remotely with files and folders of your phone, but also track its movement on interactive map. The most convenient of them is AirDroid (download). For her full use your phone must have ROOT access, that is, full control over the entire system.

I just want to warn you that after opening all access rights, your phone will lose the factory warranty, so do it at your own peril and risk.

If this is the first time you've heard this concept, then your device most likely does not have root access. Obtaining superuser rights is a separate big topic, which I will write an article about in the future, but for now, watch the video at the end of the article, which I used to root my Samsung Galaxy Tab and Galaxy S2, as well as my detailed video tutorial on the Airdroid service.

For other devices it is also easy to find videos on YouTube.

So, download and install the AirDroid application from the Google Play Store and launch it on Android.
The program has two modes of operation - through home wifi network or via the Internet.

Let's start with local. Go to your computer at http://192.168.1.88:8888. The phone will display a request to allow the connection - allow it.

After this, the main screen with various program features will open on the PC. In the right window there is information about the mobile phone, in the left there are icons that you can use to control the phone, namely, transfer files, play music, movies, pictures, use the phone camera (by the way, this is a good way to use your device in a video surveillance system). There is no point in going into detail about each, but the most interesting properties are remote writing and sending SMS directly from the computer, as well as monitoring the mobile monitor (menu item “Screenshot”).

If you want to have access to the gadget via the Internet, then go to http://web.airdroid.com. Here we will need to register in the service - the process is familiar and uncomplicated.

After registration and authorization, we will be asked to register the phone in this service. To do this, take the phone again, go to the application and click on the figure icon in the upper right corner.
Enter your account information here.
In the next window, click “OK”. Then “Enable” - we allow the application all administrative functions.

We return to the computer, log in again or simply refresh the page and get the same access as in the case of local connection. There is only one small BUT - when working with an Internet connection through the AirDroid service, you have a limit that limits the amount of data transferred. At the time of writing, it is 100 MB.

But this type also has undeniable advantages. For example, the phone search function - if you suddenly lost it, or it was stolen, or it’s a child’s phone, and you want to track where it is in this moment, then the location of your device will be shown on the map (provided it is connected to the Internet via wifi or Mobile Internet).

That's all for now! We will get to know some other programs in detail in future articles, so subscribe to the blog update feed - it will be interesting!

Android Remote Control

As if he knew what I was writing this article, Google has literally just launched a new very convenient and useful service for operating room owners Android systems, which allows you to monitor your phone in real time on an interactive map. Until recently, such a feature was only available for Apple owners - now we don’t have to feel deprived. The benefit of this service is that if your phone is stolen or you lose it, its location can be easily determined. It is also very convenient to monitor your child’s movements through the phone. Previously, this was possible when installing third-party applications that required root access to the phone, which I wrote about above (about AirDroid), but now you don’t need to install anything additional to track the location of your mobile phone.

First of all, you need to attach your phone to this account. If you didn’t do this the first time you turned on the phone, when you were asked to create accounts in Google and Samsung/HTC/LG (or whatever you have), then you need to do it now.

Go to your mobile phone and go to the “Settings > Add account” section

Select “Google” here

If you are registering on Google for the first time, then select “New”; if you already have mail and an account, then you can connect an existing one. I will select “Existing”, enter a login in the form of a Gmail mailbox address and a password for it.

After that, on the phone, pull down the top notification panel and open what you just received from Google and activate the remote device manager.

We return to the website, refresh the page and get a map with a point indicating the location of your phone.

That's all - to consolidate your knowledge, I advise you to watch the video tutorial. This concludes our phone surveillance - I hope you found it interesting!
