Ive had other systems. ADT, xfinity and simplisafe. I would have saved alot of headache and been alot happier if i would have went with vivint earlier. Yes it is more expensive but 1000 times over worth it. The system can do things others cant. The cameras are absolutely incredible, the new spotlight feature is something out of a movie! The monitoring response is incredibly fast and the 2 way intercom on the panel was an excellent idea. The customer service is what ive been looking for. They've changed my security experience forever
