I saw the video cameras at the entrances, but thought that he was just concerned or had nicer things, or both.

Get an alarm system.Also, consider installing dummy video cameras (unless you want to spring for an actual video surveillance system).  

Have you had a plumber come out and do video inspection of the piping or useinfrared camera to determine if there is a leak?

Josh found the CAMERA.

For instance they have remote cameras you can put inside of the place when they left that upload feeds online.

Just uses your camera to map out the walls and create a floorplan automagically.
