For many car owners, installing a rear view camera is a real lifesaver when parking or reversing. The essence of the device is to transmit a video image from a camera installed in the rear to a display in the car. The feature of rear view cameras is a wide viewing angle and ease of installation, which allows you to get the job done without the involvement of specialists, and save money. The main thing is to take into account the differences that exist in various models. Let's consider this question in more detail.
When selecting a rear view camera, the car owner proceeds from his own evaluation criteria - prices, appearance, display size and others. But there is one nuance. Some models work with a specific brand of car, and are "sharpened" for its design features.
There are two types of devices:
The advantages of the second type of devices are obvious, because there is no need to lay wires through the cabin. All that is required is to install the camera and display, then set up the signal transmission and use the device. But the caveat is that wireless cameras do not work with some types of radio tape recorders. Therefore, before buying and installing a product, it is worth studying the manual for the device and consulting with specialists. After that, you can decide whether the model is suitable for your car or not.
The main step that is taken before installing a rear view camera is the purchase of a product. Focus on the following options:
Next important point- installation point of the rear view camera. One option is to mount the device in the fixation area of the license plate light. A number of manufacturers provide a special place in this area for mounting the camera. If the camera is placed on a truck, great option can become roof mounting. The advantage is reliable protection against pollution, but it will be inconvenient to maintain the device.
To make the camera invisible and prevent its theft, special brackets are used. Special attention should be paid to the slope of the product, on which the viewing angle depends. It is important that the camera covers all areas that fall into the "dead" zone when assessing the situation through the side mirrors. When installing a rear view camera, it is important to focus on the quality of the transmitted image - it should not be distorted.
So, when choosing a place for fastening, it is important to consider a number of factors:
Self-assembly of the device involves several steps. First prepare the place for installation, then fix the device itself. Now it remains to connect the device to the reverse signal, and combine it with the display in the car. The main difficulty is the laying of wires, which are difficult to make invisible.
As mentioned, in some cars it is possible to install a camera instead of a ceiling lamp that provides license plate illumination. The algorithm of actions here is as follows:
How to repair and adjust the rear view camera if it does not work -.
One option is to install a rear view camera, directly under the ceiling (without dismantling it). The downside is that, with this installation, the device will stand out against the background of the license plate and become noticeable to others. To eliminate the need to drill additional holes in the bumper, it is better to mount the camera on a bar with lighting lamps. Here the algorithm is as follows:
The place for fixing the rear view camera, as a rule, is selected, taking into account design features car. If the selected model has the appearance of a door peephole and a thread, it can be mounted in place of the trunk lock. The algorithm is this:
The advantage of this installation is the invisibility of the rear view camera. Also, the product is less prone to contamination when compared with mounting on a bumper. In addition, self-mounting and configuration can save the budget, gaining invaluable experience.
Do not save money on buying such a useful device. It is better to spend money on this device than to lay out a larger amount to repair someone else's and (or) your car. Installing a rear view camera is a chance to avoid many problems and increase the level of comfort when using a car. Moreover, at self installation, you can save a lot of money, which you definitely need to use.

Or directly), we offer you tips, and sometimes even requirements, for connecting the power of the camera in a car, as well as a small but very detailed video instruction. Let's conditionally divide the article into several parts:
Connecting the rear view camera power is an important and much more time-consuming process than it might seem at first glance. Improper power supply can lead to damage to the device itself, damage to the wiring of the car, incorrect operation of the camera, or poor or unstable picture quality.
Primarily, "+" and "-" of all connected devices must be taken from the same place. This is an axiom and a cornerstone of connecting electronics in a car.
Secondly, study the logic of the installed equipment. As a result, the connected camera should not stand out from the overall picture. What does this mean in practice:
If, according to the logic of the already installed equipment, all electronics turn on at the moment power is supplied to the head unit / monitor, then the camera must be connected accordingly. In many cars, the factory reversing camera (even if it is not available) is designed to turn on at the same time as the car's ignition is turned on. This approach provides an already warmed-up matrix and excellent image quality, especially at night, and also, in some cars, activates the video input for the camera.
Our engineer, whom you all know, told us how to properly connect the power of the camera. We strongly recommend viewing. And don't forget to like the video and subscribe to our YouTube channel if you haven't already.
Now you know all about correct connection rear view cameras. Stick to these rules and you will get a very useful and stable helper. If your camera is unstable after connection or gives a bad picture, you know what to ask your installer.
We strongly recommend that you contact only trusted workshops and installers who know a lot about electronics. Otherwise, you can lose time, money, and nerves.

The modern market offers buy universal rear view cameras two types: CMOS and CCD. They differ in the manufacturing technology of the matrix, which form a digital image. Each type of camera has its own strengths and weaknesses, so making the final choice is not always easy. Let's learn about the features of each type.
Features of CMOS cameras
Cameras with CMOS sensors are characterized by low power consumption, besides, cell readings can be performed randomly in them, but this is not possible in the CCD matrix. This eliminates the "smearing" or "smearing" effect where bright point objects result in vertical pillars of light. In addition, in CMOS cameras, a significant proportion of the electronics is located on the cell itself, which increases the ability to control both the image and the matrix itself.
However, cameras with CMOS sensors have a number of weaknesses. One of them is the small dimensions of the photosensitive element in relation to the total pixel size. In addition, due to the location of the electronics on a significant part of the pixel, the area of the photosensitive elements is reduced. This leads to a decrease in these characteristics.
The pixel also undergoes electronic processing, resulting in an increase in the number of noise that occurs in the picture. Another weakness of cameras with CMOS matrices is the presence of the "rolling shutter" effect, which is associated with a short duration of the matrix scan. It occurs when an object or operator is moved by high speed, which may cause horizontal stripes to appear in the image, object distortion, etc.
Distinctive features of CCD cameras
Universal rear view cameras CCD, which is more expensive than CMOS devices, allows you to get a better picture. Shooting is accompanied by the creation of less noise, besides, they are easier to disperse. Also matrices of this kind are known for excellent efficiency. Their duty cycle is almost 100%, while only 5% of photons are not registered by the matrix. It is noteworthy that in the human eye, this figure is only 1%.
If we talk about the shortcomings of CCD matrices, then the processes occurring in them are highly complex. The camera uses various additional devices, which increases the energy consumption and the cost of the device. In addition, products with a CCD matrix are more capricious in use.
The rear view cameras presented in our store have detailed description characteristics, so you can easily purchase the most suitable device. And if necessary, the store staff will help you make the right choice.
Car manufacturers are constantly improving the performance of their products. Equipment becomes more reliable, more functional and more economical in maintenance. Along with this, special developments appear that improve the ergonomics of use. vehicle. In this regard, rear-view cameras with parking lines deserve attention, which not only facilitate the tasks of the driver, but also increase the overall level of safety. Such equipment is useful not only for beginners who have just passed their license, but also for experienced drivers who, due to certain external factors, may be forced to turn to an electronic assistant for help.
Traditional models of the first generation of rear-view cameras did not have this option, broadcasting a “clean” video stream through the display in standard mode. Modern versions are capable of applying graphic contours to the transmitted image. Depending on the specific design, this may be a pair of contours or an extensive grid over the entire area. In both cases, the task is the same - to help the driver navigate in the target space and calculate the distance to the nearest objects. Also, some reversing cameras with dynamic parking lines provide the ability to synchronize with navigators, which expands functionality both devices.
In the operation of such equipment, the importance of optics is extremely high. Experts recommend giving preference to cameras with HCCD matrices, which are distinguished by a high-quality "picture" and small size. The more detailed the image, the larger should be the screen on which it is displayed. Models with resolutions of 510 x 492 and 720 x 480 are considered standard. But it also makes no sense to acquire a too massive display, since the overall equipment on the dashboard interferes with the natural view. In addition, rear view cameras with parking lines can have different coverage angles. It varies on average from 120 to 170 degrees. On the one hand, an increase in visibility is a plus, since the car owner controls the area larger area. But almost always, such models lose to analogues with a smaller angle in terms of image quality - detail and clarity suffer, which is especially evident in the evening and at night.
In the segment, universal, regular and mortise camera models are distinguished. They do not always have obvious operational differences, but in constructive device the difference is quite noticeable. As for universal models, their technical specifications are guided by the installation in almost any car - on the bumper, body parts, license plate equipment, etc. However, when choosing such a device, you will have to accept that the camera will be visible to everyone around. In turn, regular rear-view cameras with parking lines are initially oriented towards integration in a particular car. For them, the manufacturer provides a special place in the license plate area. But after installation, the camera will be barely noticeable. Mortise devices combine the advantages of universal and regular devices. On the one hand, they are securely hidden in the body structure, and on the other hand, they are suitable for a wide range of vehicles. But to install this type of camera, you will need to perform installation measures.
The classic way to transmit a signal between the components of on-board automotive electronics involves the use of a local power grid. This may be standard fittings, but it is most often paired with central power supply lines. To save car enthusiasts from painstaking cabling, manufacturers began to master wireless rear-view cameras with parking lines with a monitor that broadcasts a radio signal. To organize the infrastructure of this connection, the installation of transmitter and receiver modules is required. That is, the video signal will be sent wirelessly from the camera to the main unit of the parking system. The concept is easy to install and operate, but it has two drawbacks - broadcast instability in conditions of strong interference and a limited coverage area (10-15 m).
The installation method will depend on the camera type. Two options are fundamentally different - surface mounting and mortise. In the first case, the device is simply applied to the target surface using the supplied adhesive fixators, after which auxiliary external holders can be used. It is advisable to use the mortise type of installation if the connection of the rear view camera is wired. Creating a hole in this situation performs the task of installing the device and provides access to the on-board network. The camera itself is fixed in a special seal and clamped in the prepared socket.
The next step is to connect the components of the system. As already mentioned, wireless models do not require traditional cable connections. But even in this case, output RCA connectors can be used. In the standard rear view camera connection scheme, the main panel is connected to the battery and the audio and video outputs are connected. Again, depending on the functionality of the model, it can also be associated with third-party devices, including a navigator, TV tuner, etc.
According to reviews, this is one of the most reliable and durable systems, which is not surprising, since the design is based on a metal case. The camera itself also assumes the use of protected mounting locations - for example, in the frame of a license plate. During operation, it will be possible to change the angle of inclination of the lens depending on the area of interest. Although this feature may not be required, since the viewing angle is already 170 degrees. Like other rear view cameras with parking guidelines from the AVIS family, this version allows you to broadcast both direct and mirror images. Signal reception is carried out by a display with a resolution of 510 x 492.
This model is also included in load-bearing structure license plate. During operation, the lens is protected from dirt and mechanical stress. The features of the device include the presence of two sensors, which are located on the sides of the camera. They allow you to fix the distance to surrounding objects. However, the detection distance is short and is only 20-30 cm. Like the best rear view cameras with parking lines, this version is equipped with a beeper. This functional component provides the ability to sound an alert if the distance-scanning system has detected a critical approach. Also, the advantages of the Blackview solution include a solid 720 x 480 screen and a wide operating temperature range.
The preference for this model is mainly given by car owners who want a simple and low-cost tool to facilitate the parking process. The device is easily mounted with two lugs. Then it remains only to direct the camera to a profitable area and connect it to the central panel. Despite the budget class, this version provides a wide viewing angle of 170 degrees and produces a detailed image. Also in the structural plan, rear view cameras with parking lines from AutoExpert are rarely criticized by users. The element base and the assembly of devices are made at a high quality level.
If it is possible to integrate the standard model, then it will not be out of place to prefer this option as the most suitable for installation. Mortise devices, with all the pluses, imply a violation of the structure, and this is best avoided. As for universal rear view cameras with parking lines, this choice should be made if the device is assigned an auxiliary function. For example, if a set with sensors acts as the main assistant in the parking process.
Wireless communication causes ambiguous judgments for many users, but they all boil down to the fact that in order to ensure signal reliability, it is worth initially considering a wired connection scheme. For key performance indicators, it is desirable to focus on your own needs, taking into account the operating conditions of the machine and the level of driving skills of the user.
The rear view camera helps the driver when parking the car. It is very important to choose a model that would meet all the requirements for these devices. The article will help you understand existing species devices, their characteristics, the right choice.
[ Hide ]
The rear view camera is designed to transmit the video image behind the car to the monitor inside the cabin. It connects to a standard monitor, video navigator or an additional screen. Such parking devices are present in almost all modern cars. With IR illumination and changing the viewing angle, they help the driver to assess the situation behind the car and park correctly, even in absolute darkness.
When choosing a parking camera kit for a car, it is important to know the main characteristics of these devices and consider the following factors:
An important parameter of a video device is its matrix.
In its production, one of the technologies is used:
Matrices made using CMOS technology do not work well in low light, transmitting an image with poorer quality. Despite this, matrices of this type have two advantages: progressive scan - both high-quality and low-quality signal lines are sequentially transmitted to the monitor; they are cheaper than PSZ matrices.
Devices with surface-charge communication transmit a better image to the monitor in low light, but they require more energy and lose to cheap counterparts in speed (video by Volodamdes).
There is a wide variety of parking cameras on the automotive market.
They can be divided into the following three types according to their location:
Universal cameras have many advantages over standard counterparts. They have simple design, therefore, by purchasing a kit, a universal device can be easily mounted anywhere in a car. The shape of the universal video camera resembles a butterfly. The main advantage of these devices is their low price. Universal video cameras are hermetically sealed, thanks to modern materials They are scratch and moisture resistant.
There are universal devices that are mounted in the rear bumper of a car. They are equipped with IR illumination, which provides visibility in the dark.
The disadvantage of these universal models:
Most simple option is a rear view camera built into the license plate. It comes as a kit and does not require installation, the driver does not need to think about installation. In addition, the driver can adjust the viewing angle in relation to the horizon of the video camera built into the license plate.
An important advantage of built-in devices is the ability to install on cars of any make and model.
The device transmits a clear picture. Its design is sealed and weatherproof. It can be operated at temperatures from -30 to +50 degrees. To improve visibility at night, IR illumination is installed. The disadvantage is easy access, anyone can damage or remove the device.
Rear view camera - best option. It is installed in the places provided by the manufacturer. Usually, the trunk opening handle, the IR lampshade of the license plate light are chosen as the place of standard installation. IR illumination improves visibility at night.
The advantage of regular cameras:
A convenient option for viewing the space behind the car is a rear-view mirror, to which the video camera is attached with a tripod. A mirror option is possible, in which a rear-view camera and a video recorder for a car with a monitor are built-in. A retractable rear view camera with IR illumination can be installed on the car.
According to the method of installation, the video camera can be mortise and case.
The image from the rear view camera can be transmitted to a specially installed monitor, a regular car screen and a car navigator. To connect the device to any type of monitors, you need a video output that supports PAL or NTSC TV signal. It is important that the devices are compatible. The instructions include a wiring diagram.
Transferring an image to the screen can be done in two ways:
Installation by car service specialists is expensive. It is more profitable in terms of finances and time to buy a kit and install it yourself using the connection diagram.
The choice of video cameras is large, it is better to choose a standard device, but there may be problems with the size and shape, since each car model has its own standard camera. If you have problems finding a standard fixture, you can purchase a universal one that fits the parameters.
A rear view camera with dynamic markings is useful for drivers who have to constantly park their car in unfamiliar places. Thanks to the video image received on the monitor, the driver will be able to see all the obstacles in the parking lot. He does not have to, as in the old days, turn his head to assess the situation behind the car. For the dark time of the day, cars are equipped with IR illumination.
The rear view camera can be used as an addition to the car, making together a set of video devices with which you can record travel. Information from the cameras can be used to identify those responsible for the accident.
This video provides an overview of wired and wireless parking cameras, and also demonstrates the process of connecting devices (the author of the video is Observer Krasnodar).
