It is extremely difficult to park a car in a city, because you often have to back up, while maneuvering between various obstacles. In addition, there are various “blind spots” that are not accessible for the driver's view, and into which a person or animal can fall. Therefore, to make life easier for a car enthusiast, it is better to use a rear view camera.
In addition to the device, it is possible to install several parking sensors - a system of non-contact devices, which will signal about approaching obstacles.

The camera itself does not differ from a standard "webcam" or any other similar video surveillance device. Usually it is mounted on the rear of the car in the area where the license plate is located, and the captured image is transmitted to the driver in the car's interior on the installed monitor. In this case, you can use both a separate monitor and a monitor integrated into the car (for example, an on-board computer). For convenience, the picture is transmitted to the driver in a mirrored reflection, this effect is needed so that the driver does not get confused in the sides if he insures himself through the rear-view mirror. Parktronic lines (a kind of grid) can be superimposed on the resulting image, which will allow you to more accurately assess the situation behind the car.
In addition, in the Russian consumer market, rear-view cameras are technically complex devices and undergo a multi-stage quality control before they go to retail. Therefore, purchasing such devices at retail is safer than ordering them on various Internet sites. This even applies to Asian manufacturers - their products are also confirmed by Russian quality certificates.
The appearance of his car is important to any car enthusiast, so the installed camera should be either the least noticeable, or harmoniously fit into the overall design of the car.
Devices are divided into the following types:
There are also camera models whose versatility lies in their visual installation:
Devices for receiving video signals can differ in several ways. Depending on their combination, the driver can choose the most acceptable scheme for himself.
Display devices:
Wired and wireless transmission:
Wireless connection can also differ in the type of signal modulation:
As mentioned above, most cameras display images in a mirror format so as not to confuse the driver about the image in the rearview mirror. However, professionals believe that it is better to choose an option where this function will be disabled.Here a situation arises that can be compared to forcing left-handers to write with their right hand - some people are better off perceiving images in their direct form.
The rear view camera can superimpose a virtual coordinate grid with information about the distance to the nearest object on the displayed image. However, for this function to work fully, it is required to calibrate the camera as accurately as possible during its installation. Usually, the parameters required for this (viewing angle, installation height) are specified in the operating instructions. If you do not comply with these recommended specifications, the camera's grid will give false information. It will also be nice if this functionality is optionally disabled.
The more the camera model has a viewing angle, the more it can cover objects behind the car. But it is always worth remembering that the extremely wide viewing angle will affect the distortion of the image ("fish eye" effect). Also, when this angle is increased too much, the output image may appear “blurry”. Angles from 120 to 170 degrees are considered optimal. Below the minimum limit, cameras are considered narrow-focus, and above the upper limit, cameras are considered wide-directional.
At present, rear-view cameras practically do not differ from modern video equipment, and even in their designs one can find the use of professional elements (for example, lenses from "Carl Zeiss"). The following matrices are used as standard in modern designs:
In order for the camera to work reliably in conditions of minimal illumination, its sensitivity must be in the range from 0.01 to 3 Lx. For a CCD matrix, an indicator of 0.01 Lx will be sufficient, but for a CMOS, higher parameters are already needed - 0.1 Lx.
It is usually extremely small - only 628 by 582 pixels. Converting to standard values, this is only 0.3 Megapixels. At first glance, it may seem that the resolution is extremely small, but more is not required. Hardly anyone wants to park on a 24-inch widescreen monitor that can support a resolution of 1900 x 1600.
After all, rear view cameras are extremely sensitive devices, so they are quite capricious about the environmental conditions. More expensive models are equipped with special cases that maximally protect the working elements of the device from external influences, by using special technologies of dust and moisture protection. Standard devices are capable of operating in the temperature range from +25 to –65 degrees Celsius.
Devices can be equipped with additional functions:
This model is a classic budget option. It has a relatively large functionality, but at the same time its price is much lower than the flagship models with the same characteristics. Users report good picture quality when transmitting a signal in analog format. The ratio of image noise and color quality is quite satisfactory.
