I had a representative from one of ADT's subcontracted sales companies come to my house last year in August. He gave us a whole spiel about how if he could put a sign in our yard we could get a security system for free. My husband and I both specifically asked him how long the contract was for for the monitoring monthly fee and were told that it was 1 year. We specifically asked what it would cost it us to cancel after a year and he told us it wouldn't cost us anything. He told us that when a year was up we should call and tell them we were going to switch companies and they would lower our monthly payment or we could just stop it anytime after a year.
I use ADT in all of my tenants homes and they like it. I have a influx of new tenants constantly so each time that happens I change the alarm code and make them a new user login on the ADT pulse app. I realize most people won't need to do all of this extra work when it is just them using it. If it can hold up in rentals it is definitely a worth-while security system!
It's hard to beat the biggest and best. I started out with Guardian but worked my way over to ADT for practical reasons. Lots of companies aren't nation wide so if you have to move (like we do my husband is in the military) it is too much of a pain to try and get out of contract etc. My advice is go with a national company so you don't have to pay any early termination fees.
