后视系统、倒车后视系统（Rear view system, rear view system） First of all, the principle and composition of the system after the car rear view system and the rear vehicle. Principle: the car after the visual system is modified the original reversing radar, installed in the rear of the car camera images of the car tail through send signals to a transmission line installed in the location of the vehicle driving monitor, according to the vehicle by means of image surrounding obstacles, by expanding the drivers vision, to help the driver vehicle around the situation, timely find obstacles, thus increasing the safety factor of driving back, auxiliary driver safety products. Composition: simple: car monitor, reverse camera, transmission line. How to choose the car after a few elements of visual system product: (here on the 24 v cart reversing system) 1, the working voltage range: working voltage range is the key to decide depending on the system after car, because once the power supply circuit, light burning car monitors, cameras, or burn the car circuit. Cart voltage is 24 v, generally suitable voltage range as wide as possible, on the market at present there are several: a, the working voltage is 12 v, need customer to buy voltage regulator, this kind of product configuration, there are a lot of hidden trouble, because of the different product range of working voltage and current is different, and the voltage stabilizer on the market most of them are not very standard, working voltage, output current, circuit protection, etc. Products may be related to different manufacturers, the use effect and stability of is different, use the 12 v after reversing visual system, are all in use after a period of time and have a burn out display, camera. Second, the working voltage is 24 v, just is designed according to the voltage on the car, this kind of product configuration, there are also some disadvantages, because of the bus voltage fluctuation range is very large, especially when cold star
