I would highly recommend Vivint!
The service is fine and they do their job. However the door lock will not lock from the app or the keypad, only manually from the inside. When I asked customer service for help they basically gave me instructions to take the whole thing apart and re-install it. I am not a tech and I pay for a service that works...
The representative that installed my service was very professional. He stopped to explain the equipment functionality so that I knew how to use the system. I have a camera doorbell and I wish the video loaded quicker. I have that same feedback from 5 years ago. Oh well.....
Vivint's customer service was impeccable and I would definitely recommend them to family and friends
