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 "dead zones" that are not available for the driver's view, and into which a person or animal can get. Therefore, to simplify the life of a motorist, 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 that will signal approaching obstacles.

The camera itself is no different from a standard webcam or any other similar video surveillance device. It is usually mounted on the back of the car in the area where the license plate is located, and the image captured by it is transmitted to the driver in the car interior on the installed monitor. In this case, you can use both a separate monitor and a monitor integrated into the machine (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 tries to secure himself through the rear-view mirror. The resulting image can be overlaid with parking sensors (a kind of coordinate grid), 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, before entering the retail market, they undergo multi-stage quality control. Therefore, the retail purchase of such devices is safer than ordering them on various Internet sites. This applies even to Asian manufacturers - their products are also confirmed by Russian quality certificates.
For any car enthusiast, the appearance of his car is important, 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 a video signal can differ in several ways. Depending on their combination, the driver can choose the most suitable scheme for himself.
Display devices:
Wired and wireless transmission:
A 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 the option where this feature will be disabled. There is a situation here that can be compared to forcing left-handers to write with their right hand - some people are better off perceiving images in direct form.
The rear view camera can superimpose a virtual coordinate grid on the displayed image with information about the distance to the nearest object.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 indicated in the operating instructions. If these recommended characteristics are not observed, then the camera grid will produce false information. It would also be nice if such functionality is optionally disabled.
The larger the camera model has a viewing angle, the more it will be able to capture objects behind the car. But it is always worth remembering that an extremely wide viewing angle will affect the image distortion (the “fish eye” effect). Also, with an excessive increase in this angle, the output image may seem “blurred”. Angles from 120 to 170 degrees are considered optimal. Below the minimum limit, cameras are considered to be directional, and above the upper limit, cameras are considered to be wide directional.
Currently, rear-view cameras practically do not differ from modern video equipment, and even in their designs you can find the use of professional elements (for example, lenses from Carl Zeiss). The following matrices are used as standard in modern samples:
In order for the camera to work reliably in conditions of minimal illumination, its light sensitivity should be in the range from 0.01 to 3 Lx. For a CCD matrix, an indicator of 0.01 Lux will be sufficient, but for CMOS, higher parameters are already required - 0.1 Lux.
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 resolutions from 1900 x 1600.
Still, rear-view cameras are extremely sensitive devices, so they are quite capricious to environmental conditions. More expensive models are equipped with special housings that maximally protect the working elements of the device from external influences, through the use of special technologies for 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 flagship samples with the same characteristics. Users speak of good picture quality when transmitting a signal in analog format. The ratio of image noise and color quality is quite satisfactory.
