The camera show points to the road which shows the driveway, yard and front porch and per North Carolina it is not illegal.

. - Demanded that security cameras be installed on the exterior of the building

While the pipe was open, they ran a camera up the lateral to the house and found some roots, which a plumber removed. 

I recommend a camera system with a motion detector food light and if the situation calls for it, perhaps some temporary construction fencing to help reduce the invitation in.

it's times like this you wish there were a security camera somewhere nearby

I’m looking for recommendations for a reasonable priced camera inspection.

Additionally, a camera will need to be run down the sewer line. 

He assumed a opened/cracked pipe and/or a block.This crawl space door was too small for his camera, after pulling the toilet, he tried to snake it through where a toilet connects to the sewage line but ran into too many bends, and tried to snake it through the vent pipe on the roof and that was clogged (not fully blocked).

Couple takeaways from my first deal...If there is a clean out drain that's easily accessible, pay $100 for a plumber to stick a camera down there and see if there's any tree roots.

I imagine cameras are probably a better deterrent then the fence
