I was present for the install and the system never worked on day one. They came back to fix, but was never completed. The system was missing the DVR that controls the camera, so they never worked. Since they didn't work we had a break-in outside. Now customer service is saying maybe they stole the DVR when you had the break-in. Response was the break-in was outside. They are just so full of BS, that you can't get a real answer to anything. DO NO TRUST ADT, the worst
