"Love the system. Was away a few days and someone lit a firework by the windows and set the alarm off. We were notified as soon as this happened. The Police were notified also. Great service. Thank you.
Had the alarm going off and ADT sent us some batteries to replace the one that was defective."

"I'm very satisfied with the entire alarm system. The installation was neatly done professionally and the technician was very thorough in explaining how the system was set up...
and if I wanted to I can add additional devices to the system."
