Anyone have any suggestions on a dash cam and tips if I should self install or just get a pro to do it?

It's so easy to install, most dash cams just suction on, these might fall off in the heat, or double sided 3m on. Then just run the wires around the edge of the window, down the pillar and under the carpets to the cig lighter in the glove box. Most good kits will have long enough wiring and baby pry tools that come with it. You might be a cigarette lighter extension splitter depending if you need more plugs or more wire length.

Viofo A119 or A129. Come with either front or both cameras. Can't beat at the price they sell.

You can get a kit to tap into the fuse box. Watch some youtube videos, it's not that hard to install.

Any issues with draining the battery when not driving?
