ADT ensures the security of its esteemed customers by operating an interconnected network of 6 response centers across the United States and Canada. This ensures continuous coverage and monitoring even if one of the centers is experiencing technical difficulty.

With ADT, your home or business is monitored for breaking and entering, fire, medical emergencies and more every second of every day.
