One of the WORST security systems EVER! Signed up in August 2015 (3 yr contract ugh) thinking doorbell camera and medical alert would be perfect for 2 Senior Citizens. Boy was I wrong! Doorbell camera works 1% of time. Vivint repair turn time is usually over 2 weeks. And the worst part is that they can't seem to get the darn doorbell camera to work. Horrible service! You call them and all you get is lip service… They cannot support or repair their system. Biggest mistake ever! Please. Don't get this system, you will regret it!
