Ran a camera and found tree roots in the sewer line. 

I figured I would buy a quadcopter with a good camera to do my climbing for me.

I used to walk my neighborhood and took a picture of every home on the street in a 6 block square area...back when cameras used film! 

I manage mine remotely using exterior cameras (make sure snow and spa services are happening) and digital locks for check in which really allows me to only have to invest about 2 hours a week on the property.     

I mean, does that just mean that security is in place and all good, or I need to set up cameras?

Install a surveillance camera in your house facing the door and the HDTV, the camera connects to the internet and alerts you of motion. 

I am looking to install 3 security cameras on the outside of my 5 unit building. 

Oh and they install cameras around the building which can be monitored remotely independently of the manager just for an added layer of peace of mind. 

He said they may sag or start to rot after they dry... hard to tell without an experienced framer looking at it.We are hiring a plumbing inspector to come out this week to run a camera through the sewer line to check for cracks.

Things to take with you: Camera, note-taking device, business cards if you have them, generic letters that say you'll buy their house.
