After a year and a half of having this system I've had several instances where ADT did not hold up to their end of the deal. For moths, without knowing, the motion detector that I was paying for was never activated.
It took me accidentally leaving my cat upstairs and the alarm not going off to realize something was wrong. I set it, walked around, and nothing. My alarm went off last night when I wasn't home. My sister-in-law turned it off after a few minutes when I gave her the code.
My phone rang and she didn't answer. My cell phone was never called, the code word was never spoken to ADT, and the police were never sent. ADT is a huge disappointment.
Do your research before you listen to what the sales person tells you. Lies.
