Is there any chance to change only camera ( from smartphone or kospet prime 2 watch 13mpix sony cam ) that works or you need more hardware , processor for this ? I know i can put Insta360go or go2 , but maybe is the option for upgrade original cam?
You might want to look into the RunCam line of cameras. We are testing some of them and like like them. They come in both large, small, and tiny, and analog and digital. We are working on designing a 3D printed top bracket for one of them to replace the bracket that it comes with. There are other RC analog cameras that ca be used also. We have modified a home security system to monitor the video from several feeds from robots and sUAV here isa link to this hack to add video to a robot car system. This is in the RC 5.2 Ghtz ananlog band. i hope this helps some.
