Design your alarm system.

The security hub can work with up to 32 different items. This allows complex systems to be built using pet-friendly motion sensors, glass break sensors and indoor and outdoor alarms. These systems can then be controlled using the key fobs and wireless remote control key fob or by using the TCC smart phone or tablet app. You can also control your heating as well! 

Safety, security, comfort.
