DEPSTECH Dual Lens Industrial Endoscope
The 16.5-foot cable is too long for any but the biggest houses, but you can adjust the viewing screen to aim so you don't have to bend over as much. It works well for inspecting pipes and wiring.

Oiiwak Dual Lens Borescopes Inspection Plumbing Camera Industrial Endoscope Snake Pipe Camera with 4.3' Screen 1080P HD Waterproof Sewer Wall Camera with Light
This inspection camera is a great value for its price. The included 32GB card is large, and 1080p video looks good. (We found it had the most distortion of our picks' 720p videos.) The supplied lithium-ion battery is large, but the camera lasted 18 hours and 50 minutes in our tests. The easy-to-access port for attaching network cables comes in handy if you're using the camera for remote viewing or live streaming.
