I will send you my guy. I recommend a sensor for the garage door, how often have you left the house and don't remember if you've shut the garage door. The system my guy installs is a full fledged automation system. Can expand to controlling lights, shut off water main, open close garage door, etc.

I also recommend all main floor windows and doors to be sensored. Motion is a plus as well.

ADT you are paying for a tech to install their equipment. They want it back if you cancel, but there are ways around this. (Say you are moving). Monitoring is 2-8x the actual cost, because you are paying for a tech to come out to fix it. My monitoring company charges less than $15. Response time is the same!
