Connect the rear view camera to the radio. Connecting two parking cameras

Twitter

The last thing a driver wants is to damage their car while parking on a busy street. Especially if it's someone else's car.

Indeed, no matter how experienced the driver is, there will be an unnoticeable little thing that will cause trouble. In such a situation, a rear view camera comes in handy. It significantly improves visibility and avoids unpleasant incidents.

Today, many cars are equipped with this useful gadget, especially in the premium segment. But early models lack this function, which means there is a reason to pick up the tool.

Today we will talk about how to connect a rear view camera to a Chinese radio.

How to choose a system

The automotive electronics market is abundantly filled with a variety of connection kits. This is especially true for products from China.

Indeed, for some owners the quality of the transmitted picture or the backlight is not at all critical. dark time days. Therefore, it is not worth paying money for unused features.

For better understanding presented devices, you need to understand the basic parameters. These include:

Video recording resolution. The higher this parameter, the better video quality appears on the screen. Cameras with high resolution They convey in detail a picture of the smallest objects behind the car.
Matrix sensitivity. Sometimes this parameter is indicated by the “ISO” symbol. Cheap models are not equipped with sensitive matrices, this directly affects the image quality in the dark. The picture turns out fuzzy, it floats while moving.
Shooting coverage. The standard viewing angle range is 120-180 degrees. A high indicator helps make the video panoramic, it will fit into the frame a large number of space. But there is an insidious point here: at such angles they distort actual sizes items that can deceive an inexperienced driver. Therefore, the optimal solution should be sought between these values.
Camera body and installation type. Waterproof devices can be safely installed outside the car; they are not afraid of water and dirt. But they will always be available to thieves. Cameras for internal installation are installed in the luggage compartment. The space coverage will be reduced, but the device will always be dry and protected from the wrong hands.
Connection type. Standard – wired connection. A cable is laid from the monitor or radio to the rear of the car. More unusual is wireless connection. The driver does not need to remove the trim and hide the wiring. But this method requires additional accessories– transmitters.
Rear cameras with backlight function. Using such devices you can easily navigate in the dark. Illumination is performed using infrared diodes or an additional lamp. This function is useful for those cars in which the rear lights are small in size and produce weak light. Whether this type of camera is needed is up to the owner to decide individually.

It is also necessary to pay attention to the way the image is displayed. This can be a separate monitor or a 2din radio with a built-in screen. If the quality of the latter is satisfactory, there is no point in installing a second monitor.

How to connect a camera to a radio with your own hands

Initially, you need to select an installation location. There is enough space in the rear of the car, but if you take into account the coverage of the broadcast picture, the choice is reduced.

It is worth considering the location of the camera eye. It must have a view of the entire shooting angle and not be obscured by other body elements.

There are two installation options: under the license plate and under the rear window. Here it is worth considering the type of car body. For station wagons, due to the lack of a long trunk, both methods are suitable. For sedans, the optimal location is in the license plate compartment.

Let's move on to the connection. Before starting work, you need to prepare the tool:

the camera kit itself with wires;
screwdriver;
a set of keys;
pliers;
plastic ties;
electrical tape or heat shrink tubing.

Sometimes for fastening rear camera You may need to drill several holes. In this case, you should stock up on drills and drills. Some car models have a prepared place for the camera, for which you just need to remove the factory plug.

Prepare the car interior for wiring. Carefully remove the upholstery. Choose places where the cable will not experience deformation from the feet of passengers, and also avoid sharp bends of the wire. It will be reliable to strengthen the wire on the standard highway of the car. Secure the line with plastic ties.

Let's move on to connecting the rear view camera to the Chinese 2din radio. To get to the ISO connections and the rear of the audio system, you need to carefully open the front panel (or several, depending on the car) of the dashboard and unscrew the mounting screws. The standard radio can be detached.

Tip: for safety electrical circuits machine, all connections should be made with the battery disconnected. This eliminates the risk of accidental short circuit to mass.

Connection diagram of the camera cable connectors to the car radio

When preparatory work completed, the cables are laid, you can proceed to connecting all system components.

Let's take a closer look at the diagram:

The standard connection cable consists of two parts:

yellow – signal;
red – food.

Please note that the colors of the voltage wires may differ on different models.

The video signal connection is made through tulip-type connectors.

The standard method of powering and activating the camera is through the reversing lights. The operating principle is as follows:

The red wire is connected to the lights, the black wire is connected to the ground of the car.
The signal cord is connected through the trunk in the cabin to the radio via the Video In connector.
When reverse gear is engaged, voltage appears on the power wire of the camera, which activates it.
The radio detects a signal on the input channel and switches to image broadcast mode.

Very often, the connection to the radio is made through the ISO connector. In this case, you should familiarize yourself with the connection pins and find the video input.

The second connection method allows you to activate the surveillance system regardless of reverse gear. To do this, 12V is supplied to 2 wires - red and blue. The first one is connected to the ignition switch, to the key1 position - ACC. The second is connected to the reversing lamps.

With this method, the system will operate in two modes:

when shifting into reverse gear;
in the key positions key1 and key2 – Ignition, which corresponds to the on-board power supply being turned on and the car ignition.

Some radio models require manual activation shooting mode in the “settings” of the device. After activation, you should check the operation in different key positions, especially in key2.

The next step is to configure the radio itself, namely focus, sharpness and light sensitivity. Various systems offer a different set of settings, so the configurations are individual.

Tip: It is important to observe strict correctness when connecting wires. To avoid mistakes, it is recommended to assemble the system on a table and configure it. When connecting power components to the vehicle network, protect them with fuses.

Connecting a car reverse camera to a laptop

To be able to view the picture on a laptop, you need a special TV tuner. With its help you can agree analog signal with a computer.

The connection principle remains unchanged. A 12V voltage is supplied to the power wires, and the video signal tulip is supplied to the tuner. The shooting is controlled through the software.

There are models on the market for dual-zone monitoring of the vehicle space - front and rear. This solution allows you to register possible emergency situations on the road, and record the condition of the car in the absence of the owner.

Connection and configuration are carried out in the following order:

the on-board network of the machine is de-energized;
the front camera is installed on the rear view mirror holder;
install the rear one;
for an aesthetic appearance, the connecting wires are connected to the head module under the interior trim;
if the standard radio has two Video In inputs, connect the signal wires to them. In the case where the kit has its own recorder, select the location for its installation, connect it to the network and cameras;
check the connections according to the installation diagram, turn on the battery;
configure camera operating parameters.

All that remains is to test the system in motion and, if necessary, make adjustments.

Sometimes it happens that one of the cameras does not provide adequate coverage of the space in front of it. The solution is to purchase a “Fish Eye” overlay. It acts as a wide-angle lens and expands the viewing angle.

The method of connecting such a mirror is no different. The connection diagram looks like:

Often, sets of mirrors with cameras can take power from the cigarette lighter through its own connector. The owner can choose which voltage supply method suits him best.

More expensive mirror models support shooting from both sides of the car. The front camera is already integrated into the body of the product and does not require connection.

Lovers of high-quality audio systems, Japanese equipment. But they have their own nuances when connecting video cameras.

Let's look at an example at Pioneer radio, 2din format. The installation has a similar procedure:

The camera is powered from the reversing light.
The signal cable is connected to the Video In connector. Typically, in this model, a brown tulip is responsible for capturing video.
We check in the settings whether the camera is turned on and how it works.

The system works, but automatically; it will not turn on when driving backwards. It is enough to connect the purple wire of the head unit to the rear light, where the camera is. The problem will be corrected when reverse gear is engaged. The radio will understand that you need to activate the shooting mode.

The remaining aspects of installing the device remain the same.

Conclusion

Rear or front cameras have proven themselves to be the best among car enthusiasts. With their appearance on board the car, it becomes easier to navigate in cramped spaces. Their correct installation requires the owner to have some knowledge. But with the tips given, any driver can do this.

Every car enthusiast has ever had the desire to install a rear view camera, which can eliminate the problems that arise when the car is moving in the rear direction. After purchase, you will need a diagram for connecting the rear view camera to the car radio.

It should immediately be noted that gadgets that display a frontal image are not suitable. Automotive manufacturers are ready to offer huge selection gadgets that will appeal to even the most sophisticated car owners. This kind of device always displays an adapted image on the monitor of your car. This means that you will have the opportunity to view the image from the camera in the form that is familiar to you, that is, already mirrored using a variety of programs.

This kind of convenience is made specifically so that you do not have to think for a long time and figure out how to continue your movement. In other words, the adapted camera immediately gives you the ability to view images in the form in which your brain is accustomed to perceive them. In order to save yourself from all sorts of problems that car enthusiasts face, you should think about buying just such a device.

Rear view camera installation

Now let's look at the rules that a car owner should follow when installing a rear view camera. In order to this device really reflected the current state of affairs on the road, you will have to follow the rules:

If you install the gadget inside the car, it will not be the right decision. The fact is that the camera, which is located inside the car, cannot provide an adequate overview. This is due to the fact that there are other objects inside the machine that will create a glare effect, which will make it difficult to adequately reproduce the image. That's why best place, which you can choose to install your gadget, is considered to be the most illuminated place on the license plate. Therefore, you should install the camera not far from the backlight, which is located on the license plate of the car.
Many people think that a rear view camera will be of some interest to robbers and drug addicts. Such a device can only be stolen by cutting all the wires. This means that it will be completely ruined. In this regard, it will be impossible to sell it on the black market.
It is important to remember that during installation you will have to ensure that the device is located in correct position. This requirement is due to the fact that some devices have certain requirements for how they should be attached. More specifically, the quality of the image depends on this circumstance. For example, it is known for certain that with a certain arrangement of the gadget, the image may turn out upside down.

Now let's talk about the methods used during installation. It’s worth noting right away that you only need to purchase expensive rear view cameras. If you decide to save money on a newfangled gadget, then this is not at all the case when you need to count money. It is worth noting that the more expensive the device, the more opportunities there are to adapt it to the car.

In budget cars, a standard rear view camera is rarely provided for basic configurations. Most often, automakers offer it as expensive additional option. Many Russian car enthusiasts buy a separate rear view camera and install it themselves. To do this, you do not need to radically upgrade the car's electrical wiring. Connecting a rear view camera with your own hands requires basic electrical installation skills and experience in disassembling several interior and body elements. Installing a camera will improve the conditions for safe parking, monitoring the road in difficult traffic conditions

Selecting a rear view camera

Miniature rear view cameras should not be confused with optical sensors.

Installing the camera becomes the first installation step, regardless of the choice of projection device. When choosing a camera, there are several important points to consider:

Viewing angle. A viewing angle of 110 – 120 degrees is considered normal. Drivers who choose cameras with a wide viewing angle (up to 180 degrees) can better assess the road situation, but must take into account the panoramic effect, which distorts the actual size of the image.
Resolution and sensitivity. Standard Definition 628 x 582 pixels suits most ordinary drivers; increasing the image quality for the rear packing video camera does not make sense. When choosing a color sensor (CCD or CMOS), you need to consider that CCD transmits more high quality image, balances colors, but much more expensive. CMOS sensors perform worse in low light, when daylight provide acceptable color quality.
Availability of infrared illumination. Additional illumination with sufficient light provides best quality color image. In low light, the infrared source allows you to see the road behind you in black and white at a distance of up to five meters.
Video format. When choosing from the three formats that a camera can be equipped with (SECAM, NTSC, PAL), you need to consider what type of monitor the video image will be displayed on. The discrepancy between formats will make purchasing and installing a camera pointless.
Signal transmission method. The division of cameras into wired and wireless affects the cost and connectivity. Wired video cameras are universal, they can be connected to all types of monitors. Cameras equipped with transmitting and receiving modules can often transmit images only to the navigator.
Complete with cables. It is preferable that the camera be equipped with a three-wire video cable with an additional excitation wire; the power wire can be two-wire. The length of the cables also matters. The standard length (2-3 meters for a video cable, a meter for a power cable) may not be enough to connect the camera to your car model.
Case material. Experienced car enthusiasts choose cameras in a metal case, considering it more durable and durable than a plastic one.
Variability of installation location. There are cameras mounted in the frame license plate number, devices in a separate housing. A separate video camera requires a choice of several installation locations that are convenient for the driver.

The remaining standards of video cameras (presence of parking lines, power voltage, protection from dirt) are the same for most models.

Many car enthusiasts find rear view cameras equipped with a monitor mounted in the rear view mirror the most convenient.

It is difficult to deny the convenience of such a device. The monitor turns on when reverse movement begins, allowing you to see the road situation in good resolution. The main disadvantage of such gadgets is the high price, which is unaffordable for many categories of car enthusiasts.

Less convenient is the rear view camera, equipped with a folding miniature display that can be placed on the dashboard

The main disadvantage of such devices is that the view is cluttered, especially if the car already has a DVR, navigator, or a separate radar detector installed. Car enthusiasts find it more practical to use the display of one of the existing devices. Having purchased a rear view camera of any type (with or without a monitor), you need to install it in the rear of the car.

Practical operations for installing a video camera

We do not consider installing a camera behind the rear window of a car. With this installation, the camera glares and does not allow you to see nearby obstacles from behind. There is no need to be afraid of vandalism; a camera with torn wires is of no interest to buyers, but it is better to disguise it in the rear bumper or under the trunk lid.

If the camera is mounted in the license plate frame, you have no other installation options. When choosing a location, most experienced mechanics consider more convenient installation cameras above the license plate, at an angle to the road surface.

In any case, to install the camera you will need:

install the video camera in the intended location;
connect the camera power;
bring the video cable to the front of the car;
connect the video cable to the monitor to transmit the image.

The steps to install a video camera depend on your car model (sedan, hatchback, crossover) and installation location. To do this, you can use existing holes in the bumper, fifth door lid, or cut new installation locations. It may be necessary to dismantle the bumper and install additional brackets for attaching a video camera (metal plates) on the inside of the body part.

Most in a convenient way To power the video camera, most experts consider connecting the power wire to the left rear light. This may require disassembling the trunk sill and the left side of the trim. Having disconnected the rear light block, you need to use a multimeter (with the rear light on) to find the power supply contact.

For most video camera models, the three output wires are color coded. Red is used for the positive power wire, black is used for the negative wire. The yellow marking indicates the video cable. The red wire is connected to the contact of the flashlight, the black wire is connected to the car body. It would not be superfluous to provide the positive wire with an additional fuse (0.5 - 1A) in the circuit.

The most in a simple way The video cable will be installed on the left side of the cabin under the removed sill covers and floor trim. To secure the cable, you can use special tape or plastic clips. All installation operations end with the installation of the removed body and interior elements in their original places. It is necessary to finally secure the screws and clips of the casing only after testing the operation of the camera and making sure that it is working properly.

For novice car enthusiasts, the greatest difficulty is connecting a video cable to an accessible monitor. Most owners of budget versions of cars consider connecting a camera to the car radio display to be the most convenient way.

Connecting the camera to the radio (car radio display)

The video camera can only be connected to radio tape recorders with a liquid crystal display measuring at least 3 to 4 inches. Smaller monitors will not provide required quality Images. The free connector of the video cable is connected to a special output of the head unit (to find it, refer to the instructions for the radio). If such an output is not provided, it is possible to connect to the output marked VIDEO IN. If the sockets and plugs do not match, you will need to purchase an adapter.

You can see in detail how to connect a rear view camera to the radio in the video:

After connecting the camera to the liquid crystal display of a high-quality car radio, a “picture” of decent quality is displayed.

The image clearly shows the “mirror” effect when the video camera is operating, which is easy to get used to after several days of using the parking sensors.

To get used to the scale, you can go out and look at the real distance between the cars, and estimate the gap remaining to the obstacle.

Connecting a video camera to a navigator and navigation devices

Connecting a rear camera without its own monitor to the navigator is logical. Without cluttering the dashboard or center console extra screen, you are using something already familiar installed device. Questions about how to connect a rear view camera to a navigator do not arise when purchasing a device for which such an option is planned.

The packaging of such navigators indicates the possibility of connecting a video camera; the instructions indicate necessary actions user upon connection. The navigator kit may include adapters for connectors popular models video cameras

If a rear view camera is already installed, the car enthusiast can only plug the plug from the video camera into the desired connector.

If you do not have a standard video camera connection, you will need to purchase additional cables, plugs, and a special adapter. Schematic diagram The power supply from the rear light and the electrical wiring to the projector remain unchanged.

An adapter from RCA to the input to the navigator (often called a “tulip” in everyday life) is needed only if there is no AVI input. For navigators equipped with such an input, a standard video cable connector is often suitable.

Connecting a rear view camera to a tablet and mobile electronic gadgets

Of all types of electronic wearable devices (laptops, smartphones), a tablet is most convenient for connecting a rear video camera. The monitor screen size and resolution quality are suitable for work. The flat body of the tablet allows you to choose several options for convenient installation.

Often, owners of cars with a primitive radio, without a navigator, have no choice but to connect a rear view camera to a tablet. To connect a wired video camera, you will need to purchase a TV tuner (looks like a flash drive) with a video input plug.

You can often hear the question of how to connect a rear view camera to the radio. This is due to the increased demands of motorists for comfort. And also, with some features of modern car bodies. In pursuit of improved aerodynamics, car design is becoming more and more streamlined. Which does not have a very good effect on the driver’s visibility; it has become especially difficult to move in reverse. Therefore, many manufacturers provide for the installation of rear view cameras on their cars.

This allows you to park safely in almost any conditions. True, not all cars have these cameras. But it's not scary. Even a less experienced car enthusiast can carry out such modifications with his own hands.

Equipment selection

How to connect a rear view camera to the radio? Before answering this question, you need to make sure that this is possible for your radio. Normally, such a system will only function in combination with radios equipped with an LCD screen. If you don't have one, you'll have to go to the store to get one. When choosing, be sure to check whether it is possible to connect a camera to it.

Sometimes sold ready-made kits: radio+camera. But often this is far from the best choice. The quality of such kits leaves much to be desired. Its prices are much higher. You can pick up a radio and a rear view camera for quite reasonable money.

When choosing a camera, be guided by customer reviews and price. It is advisable to read on the Internet about all the features specific model. Don't discount sellers' recommendations. Sometimes you come across very smart guys there. Not worth buying front camera, she will not be able to work as she should. Consider connection options. There are cameras with wired and wireless connections.

Preparing the car

Many modern cars have a special recess for the rear view camera. This is the easiest option to install. In all other cases, you will have to tinker with preparing the place to install the camera. There are 3 installation options most commonly used:

In place of the license plate light;
Bumper insert;
Insert into the trunk lid.

The first option is quite simple. But, at the same time, the illumination of the number is reduced, which can cause problems with traffic police inspectors. Installing a camera in the bumper takes more time, but this arrangement is more effective.

To install the camera, you need to cut a hole in the bumper large enough to accommodate the “eye.” This device is most often fastened with self-tapping screws. Sometimes the camera manufacturer provides a different mounting method. This should be checked when purchasing a camera.

Installing a camera in the trunk lid is a little more difficult. It is important not only to cut the hole. But also do it as carefully as possible. At the same time, do not forget to treat its edges with anti-corrosion substances, which will help avoid problems in the future. There are several advantages to this setup. One of them is a larger viewing angle, which allows you to control the backward movement more efficiently and reliably. Also the camera location is more high level allows it to remain clean longer, which makes it reliable in conditions of autumn and spring thaw.

Connection

Many car enthusiasts make the mistake of posing on camera. constant food. This leads to rapid failure of this device, which is not designed for uninterrupted operation. That's why, optimal solution will be connected to the reversing light. In this case, when you engage reverse gear, the camera will turn on and display the image on the radio screen. When switching modes, it will turn off automatically. All this happens in automatic mode without driver participation.

Cameras can be connected both using wires and without them. Let's look at the features wireless cameras. They have a transmitter that transmits a signal to a receiver located near the radio and connected to it. The only difference between this type of camera is the absence of wires running throughout the cabin.

Connect the camera as follows:

First you need to connect the device to the rear light. To do this, you need to take the black (minus) wire and the red (plus) wire and connect them to the corresponding terminals of the flashlight. The easiest way is to insert into the wires going to the terminals. Just remember to properly insulate the connection;
For wired cameras, extend the yellow wire and stretch it around the cabin. This is usually done around the cabin, but some craftsmen simply add it to the standard harness. On wireless versions a transmitter is connected to it;
Connection to the radio is via the video in output. In general, the work of connecting the rear view camera to the radio is complete.

As you can see, there is nothing particularly difficult in this work. Be careful when connecting the camera to a power source. It is extremely important not to confuse the polarity here. Otherwise, you may burn the purchased equipment. And if at that time you also have a radio connected, then it is likely that it will also fail.

Settings

Connecting a camera is not too difficult. But, for its normal operation, it is still necessary to perform additional settings. Before setting up the camera, turn on the ignition so that voltage is applied to it. The setup is done as follows:

Turn on the radio in “settings” mode, then find the camera section and go into it;
Select “rear” from the list;
Use the buttons and joystick to adjust the focus to suit your needs.
This completes the installation and configuration of the rear view camera.

Front-camera. In addition to the rear camera, you can also install a front camera. For greater effect It is advisable to purchase a front camera with a wide viewing angle. Then she will help you out not only in the parking lot. Due to the location and great review, you will be able to safely drive onto the road due to any obstructions.

For normal use of two cameras at the same time, you need to purchase a radio with 3 video outputs. There are plenty of these on store shelves now.

Conclusion. Parking sensors are not always able to provide safe parking. Therefore, many drivers are interested in how to connect a rear view camera to the radio. This device allows you to assess everything that is happening behind you and quickly respond to changes in the situation. This minimizes the risk of damage to the vehicle.

Camera - isn't it? great way make it easier to park in tight spaces? Installing a rear view camera with your own hands will not take you much time. Let's consider the installation of a mirror with a built-in camera, as well as diagrams for connecting a remote device to a multimedia system monitor.

Installation options

There are several ways to retrofit a car with a rear view camera ():

a separate camera that connects to a standard multimedia system or a self-installed screen;
a camera kit with a rear-view mirror, on which an image will be displayed when moving backwards. This can be either a separate mirror or an overhead panel that will be mounted on top of the standard reflector.

Installation

You have to decide where exactly the camera will be mounted. Installation methods:

Optional equipment

One of the main problems is the lens getting covered in dirt and ice. Even few standard systems are equipped with such useful function, like washing the camera. If you install the accessory in the trunk lid of a car that has a rear window washer, then cleaning is very simple. You just need a tee, which will be implanted into the standard washer line in front of the rear window nozzle. As a sprayer, you can take a compact nozzle from any suitable car. Since the lens glass is small, there is no point in using a fan nozzle.

The second useful feature is the camera illumination, which in some models is built into the body. It is worth recognizing that in most cases the harm from this function is much greater than the benefits. The backlight illuminates the camera lens, and as a result, the image quality does not improve at night. A backlight problem may arise if the rear view camera is installed next to the license plate light. In this case, replacing incandescent lamps with LEDs can help. If this move does not solve the problem, you will have to make a protective screen.

Electronic component

Be careful when routing wires. The joints must be properly insulated. To prevent the wires from dangling or fraying, wrap them with rag tape, if possible, secure them with zip ties to the standard wiring harnesses, or secure them using the technical holes of the body elements. In the cabin, the wires can be pulled both below along the thresholds and behind the ceiling trim.

Installing a rear view camera with your own hands will not cause difficulties even for a novice car enthusiast, but you need to approach the connection much more thoroughly. It makes no sense to consider the rear view cameras that come with a special mirror. You just need to connect everything according to the instructions that are included with the device.

For normal functioning systems used:

two-wire wire for powering the camera;
two-wire video communication cable. To transmit video to the monitor, wires with RCA connectors (the well-known “tulips”) are used. The cores are not shielded, therefore, if necessary, they can be lengthened or cut for pulling in hard-to-reach places. In some options for correct operation system, an additional excitation wire will come out of the RCA connector.

The excitation wire activates the radio screen with a “positive” current, causing the system to automatically switch to the mode of broadcasting images from the camera. The field wire is not required for all multimedia systems, in some devices automatic transition to the rear view camera is carried out via a video link. If such a function is not provided by the radio or the device is not connected correctly, then you will have to manually change the image on the screen by pressing a special button.

Connection methods

You can link the rear view camera and the monitor in the cabin wirelessly. This will require a special module. The module's power is connected to the reversing lamp, and from the module it goes to the camera. Second wireless module connects to the monitor's power supply. The disadvantage of this method is interference, which often interferes with normal image transmission. Also, this method is not suitable for radios that require an excitation wire.

Let's take a closer look at the classic connection option. The essence of the above circuit is to connect the camera's power to the reversing light, the voltage at the terminals of which appears only after reverse gear is engaged. The connector (“tulip”) is connected to the standard output on the radio or screen intended for video communication. The excitation wire must be connected to the output of the radio, usually marked as “Reverse”. You can find out whether an excitation wire is required for your multimedia system from technical documentation to the radio. At this point, do-it-yourself installation and connection for most cars can be considered complete.

Lamp fault monitoring system

What should you do if you have installed a rear view camera on your car, but it only works when the car is turned off? Many modern cars, usually of German origin, have a lamp monitoring system installed. The PWM controller sends rectangular positive pulses along the power wires of the lighting fixtures, which help detect burnt-out lights at the rear of the vehicle. Since the lamps have inertia, current ripples do not affect their operation. But the reversing camera will not work correctly with such interference.

To prevent this effect, the camera must be connected to the reversing light via a relay powered by the cigarette lighter (where the current will already be constant). In this case, “+” from the 3X lamps must be applied to the relay winding only after rectification with a diode and smoothing of ripples with a capacitor. The “minus” for powering the camera must be taken as far as possible after the “mass” of the 3X lights.

We invite you to watch the video from detailed description a way to eliminate interference so that you are guaranteed not to have problems with the picture on your car.
