[0002] With the development of modern automotive electronics, in-vehicle camera systems have been widely used in applications such as vehicle monitoring, parking assist, and blind spot detection. Traditional in-vehicle camera systems typically use wired transmission. Such systems include at least one power cable and a data cable for transmitting video signals, which typically connects the camera to the in-vehicle display. However, this wired transmission method has the following disadvantages:

[0003] First, wired transmission requires running multiple cables inside the vehicle, which not only complicates installation but also potentially interferes with the wiring and aesthetics of other equipment inside the vehicle. This is especially true when adding camera systems to construction vehicles or large vehicles, where the difficulty and cost of cable routing increase significantly.

[0004] Secondly, traditional wired transmission systems typically integrate a display and transmission box, often with dedicated cameras. If a component in the system fails, such as a damaged camera or display, the entire system often needs to be replaced, increasing repair costs and time.

[0005] In addition, traditional wired systems usually do not have remote monitoring or cloud storage capabilities, and users cannot view or store video data in real time through mobile devices, which poses certain limitations in vehicle remote monitoring and data management.

[0006] To overcome these issues, wireless in-vehicle camera systems have begun to emerge. These systems use wireless transmission boxes to wirelessly connect the camera to the vehicle's display, simplifying cable routing and increasing the flexibility of the camera system. However, most wireless systems currently on the market have limitations: they are designed for specific displays and are not compatible with other displays. Furthermore, the wireless transmission boxes are limited in functionality and generally do not support multiple remote monitoring and data storage methods. Summary of the Invention
