What is the video standard of the original car camera?

CVBS (Composite Video Blanking and Synchronization) is the video standard usually adopted by the original car camera. This is the standard of analog video signal transmission, which is often used in car cameras and monitoring systems. The main characteristics of CVBS system are simple signal transmission, low cost and strong adaptability.

The reasons for the CVBS system are as follows:

1. Compatibility: CVBS is a widely used standard, and almost all TV, monitor and video devices can receive and decode CVBS signals. This compatibility enables the camera of the original car to cooperate with the car navigation system or the rearview mirror display to realize the transmission and display of video signals.

2. Simplicity: The video signal of CVBS system only needs to be transmitted through coaxial cable without complicated digital decoding and coding process. This simplicity makes the design and installation of vehicle-mounted camera more convenient and reduces the cost and complexity.

3. Cost-effectiveness: The cost of CVBS cameras and related equipment is relatively low, because they use analog signal transmission technology and do not need complex digital conversion and processing circuits. This makes the original car camera more cost-effective in automobile manufacturing and can be widely used in various models and brands.

It is worth noting that with the continuous progress of technology, digital video formats (such as HDMI, USB, etc. ) has also begun to be applied to car cameras. These digital formats have higher image quality and transmission efficiency, but they also bring higher cost and complexity. Therefore, when selecting the camera of the original car, it is necessary to comprehensively consider factors such as cost, compatibility and performance to meet the vehicle demand and budget requirements.
