Working principle of car camera:
The equipment power is connected to the rear taillight. When the reverse gear is engaged, the equipment synchronizes the power supply and enters the working state. The collected video information is sent to the wireless receiver placed at the front of the vehicle through the wireless transmitter. The interface is transmitted to the GPS navigator. In this way, when the receiver receives the signal, no matter whether the GPS navigator is in any kind of operation interface, the LCD screen will be given priority for reversing image video.
The difference between a car camera and a car monitor and a car DVD navigator when using a portable GPS navigator, and when a car monitor is used, the car monitor does not need to be turned on, as long as the car monitor is in the reverse position, the car camera image will be automatically displayed; Generally, the image can be displayed only when it is turned on; and when using the portable GPS navigator, the image can only be displayed when the navigator is turned on.
With the rapid development of automotive electronics technology and security technology, vehicle cameras have become an indispensable hardware for traffic safety. Let ’s take a look at what are the requirements for installation.
1.
