I want to put this device on my mom's car, as she has been having a hard time with rear parking lately. I need the camera to give good video quality and be easy to install. What types of rear parking cameras do you know?

Then you probably won't want to go with a drop-in rearview camera because you have to drill through the rear bumper. I got a universal overhead version from T1A Auto https://www.t1aauto.com/collections/gas-struts to mount above the license plate. I first tried to install it following the instructions, which were generally clear, and to check, I found a YouTube tutorial to make sure I put it in correctly. The only difficulty was connecting it to the electronics, and that was because I got tangled up in the wires, which is my weakness. But in the end everything worked fine and it took me about 15 minutes to install.
