Vivint just rebrands Linear's 2GIG then acts as though it and the alarm.com back end is theirs when in reality they do a *** poor job installing the 2GIG system (hence numerous call backs to fix issues), and monitor the system at exorbitant rates and lock you into a contract that is near impossible to cancel auto renewal on (hence the numerous states suing them in, and the 2000+ complaints on the Utah BBB page).
