I've had VIVINT for 3 + years only because I've signed a contract and have no choice but to pay for the product. Hardware falls off, VIVINT, broke my secondary DMZ to run the camera, they don't show up on service calls, keyless entry never worked from day one and they never came back to fix it. I was told I had a wireless system but it was tied into my original wired system. Its an absolute mess. Customer service reps on phone are kids with no bedside manner. I disconnected my VIVINT system and pulled the batteries out. With in minutes I had an email from VIVINT saying there was a power outage in my area affecting 2% of the population!!! WTF. I pulled the power and backup battery myself. At this time not one rep from VIVINT even called me. WOW DO NOT PURCHASE this product.
