I made the mistake of using ADT for security when I purchased my house. I have had nothing but problems since that time.
Customer service is the worst, if you send a complaint via email they do not respond, you have to watch your billing compared to the price you are quoted as they will over charge you. I also got a monitor where the battery only lasted a couple of months. They said they would send another, for free, then found they didn't have any in stock and I would have to go to Best Buy to go purchase. Despite their horrible customer service and bad equipment you are stuck in a contract you can't get out of.
Lesson learned. Do your research.
