Rear camera.

I've tried searching but is there any kind of small camera that can link to a phone via Bluetooth or something like that. Planning a long trip and would like a camera facing the bed and trailer to keep an eye on the load. Has anybody else done this mod?

 

If only gopros didnt run at 200°

 

I thought about putting my GoPro up there and linking it to my iPad but it would be a pain in the ass takingbit on and off whenever I leave the truck. Worried somebody would take it in a split second

Says it uses a usb cable for power.
They have others like it not sure on the power cords? May work or a cheap front and rear dash cam.

 

I was thinking about mounting it inside, but i guess that depends on the amount of stuff inside the cab and if the window was blocked, then the amount of stuff in the bed which may block view of trailer.

Still amazed how hot they run tho
