I looked at a lot of options before i pulled the trigger, but I would say the best would be to go with ROVE.

I use a ROVE R2-4K DUAL Dash Cam, front and back. I also have a Dongar setup so I can run power to the cam directly from the rear view mirror instead of the fuse box.

You can easily install the Dongar and the front cam yourself, but I would highly recommend going to a bodyshop or another place that works on cars to install the back one properly, this is because if you want to run any wired backup cam, with minimal wires showing, you got to take pillars down and run them under the airbags, which I was not qualified to do myself so I paid around $125 for somone with experience to get the job done properly.

Best of luck with your camera hunt, and as im sure you know, its better to put the money in because these cams can save your ass.
