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. ?

This product has certain requirements during installation because of its special installation. It needs to be small in size and light in installation. It cannot affect the passenger's riding environment and needs to be easily fixed, which will affect the monitoring effect. The most important thing is to have an infrared light to facilitate monitoring in poor light. It is recommended that you use the small hemisphere and conch camera with built-in infrared lights. 5. Because the industry has just started, the customers' requirements for this color are not high at the beginning, and the price of color is more expensive, but with the development of technology, color cameras will also become more and more widespread. 6.
