Recording Built In Cameras

My 2020 Offroad has at least 5 cameras. (Front, Rear, Left, Right, Under). It would be really cool to be able to record the imagery from these cameras, either on-demand, or all the time. Why buy a "dash cam" when I already have more cameras than I need?

Does anyone offer a product like this?

 

Was thinking about this again at work today. Wish there was a way....

 

OEM cameras are analog and not super high res, so it depends on your use case. These run into a control unit on models that have the 360/birds eye view options so you'd have to decide whether you want to take the merged output signal or record all 4/5 channels separately.

There are single and multi-channel DVR options. Most of what is out there appears to be for home use (consumer video or security system). Some of these do record to SD cards. The security system kits could loop recording.

Most likely you'd be looking at some custom work to tie it all together in a vehicle application.
