The ADT touch pad is a key feature, and, in many ways, functions as the “brains” of the home security system. The touch pad is a wall mounted unit that
owners use to activate the system so that it is prepared to alarm when triggered. If a door or window contact is broken, or an interior motion sensor is breached, an audible alarm will go off in the home. ADT systems can be customized to include a two way intercom. If an interior, or exterior, siren goes off, the voice of a live
ADT security representative will come over the intercom to ask the homeowners about their safety and confirm that help is on the way from the police. ADT smoke sensors sound off if a fire is detected.
Also, many systems use motion sensors that compute the proximity of a room’s walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion.

Audible exterior sirens are also beneficial if you live in a populated neighborhood with neighbors close by, as they will hear the alarm; however, the audibility of the siren may be marginally beneficial if you live in a remote area where neighbors’ homes are out of range.
