Modern cars can be equipped with any equipment that will make the process of driving a vehicle not only simpler and more convenient, but also safer. For example, more and more often for a better parking, a wireless rear view camera is installed. Today, manufacturers offer various design solutions for this device, so every motorist will be able to choose the best option for themselves.
Varieties and features of cameras
It should be said that the rear view camera is only a small part of the car parking system. Modern devices can be a separate monitor or a built-in mirror in the rear-view mirror . It can be mounted in a navigator and even a radio tape recorder and many other elements of the vehicle. Accordingly, the wireless rear view camera should be selected in accordance with certain requirements. It may seem to someone that to achieve a simpler and more convenient parking, you can put an ordinary car camera, but still there are a number of rules that you must follow:
- Devices are sometimes used in extreme conditions with temperature extremes and various weather events.
- You can install the camera both on the bumper and on the license plate light, while the devices will vary in design and mounting features.
- A wireless camera should be of high quality, that is, to shoot clearly not only during the day, but also at night.
- The feature of the device, which is mounted at the rear, is that the driver must see the captured image in mirror image.
- Parking lines should pass over the image, allowing you to correctly calculate the distance from the car to the object.
How to choose?
The wireless car rear view camera should be selected based on several rules:
- firstly, it is important what design it will be;
- secondly, you need to determine where the image will be displayed;
- thirdly, it is necessary to choose a method of outputting the video signal to the monitor;
- fourthly, determine the technical parameters of the device (for example, the type of matrix, mirror image, or something else).
So, the design plays the most important role. This is due to the fact that any driver seeks to equip his car as harmoniously and accurately as possible. Most often, the camera is mounted outside the vehicle, for example, on the bumper. And mounting inside, say, behind the rear window, is practically impossible, because in this case the camera will be too high, and therefore the review will not be very successful.
Design Features: Overview
So, a modern wireless rear view camera can be produced in several varieties:
- A regular camera, which is mounted instead of the standard backlight plate. Such a device is also a backlight, while it differs by invisibility, ease of installation without damaging the car. True, this variety is more expensive than other analogues, moreover, it is not suitable for all brands of cars.
- The mortise chamber is mounted in the rear bumper, and this requires drilling holes. It is with the help of it that the device will be fixed on a latch or nut. The device is compact, but for its installation you will need to drill a car, and not every driver will like it.
- The universal rear-view camera has a simple design, so it can be installed on any surface of the car: both on the bumper and on the body. You can attach the device using tape or screws. The disadvantage of this camera is a noticeable look. And when using screws without holes in the car can not do.
- A license plate camera is also a universal and practical solution, since it can be installed on any car. Such a device is a swivel and is built into the design of the frame, so it will not be noticeable to others.
Thus, the best option is to choose a camera that will be less noticeable.
How is information displayed?
The image can be displayed on a monitor, which is separately located on the dashboard in the car, is built into a sun visor or a salon rear-view mirror. In addition, there are varieties in which the image is displayed on the car navigator or the screen of the head unit of the machine (in this case, a free video input is required). The most popular wireless rear view camera, a monitor which is located in the passenger compartment. In this case, the image will be transmitted in two ways:
- Through a video cable that runs from the camera to the salon to the monitor. With this solution, the video signal is transmitted more reliably and will be protected from interference. The only negative is the need to remove the sheathing for laying the cable.
- The wireless method is simpler because the signal is transmitted through radio waves. But its range is only 15 m, while electromagnetic interference can affect the quality.
Optical system: what to consider?
A wireless rear view camera is often chosen precisely from the point of view of the convenience of its operation and ease of installation. However, the optical system also plays a significant role. It is worth paying attention to such key parameters as the viewing angle, the type of matrix, the degree of illumination, the color system, the number of TV lines, IR illumination and more. So, the viewing angle in the camera affects how much space it will cover when shooting. The optimal parameters are 120-170 degrees.
As for the matrices, modern devices use CCD or CMOS. In the first case, the best photosensitivity is shown in the evening. But at the same time, the read speed is low. In CMOS, the photosensitivity is high both day and night, they are characterized by speed. Yes, and the price of such devices is cheaper than the first option.
All existing rear-view cameras for cars today are colored, which greatly facilitates the perception of information. A feature of a good device is the ability to draw parking lines over images. They allow even an inexperienced driver to correctly calculate the distance to the obstacle and park more accurately.
Conclusion
Thus, you need to choose the right camera. Only in this case it will not be a decoration for your car, but its competent and functional addition. Today, cameras of the Neoline, Spark, Carax, Parkvision, Phantom brands are popular with buyers, the cost of which starts at 1300 rubles per device.
