"I have always trusted ADT to protect my home and family. They are conscientious and courteous. I have recommended them to my family, friends and neighbors.
They offer you the basic protection plan as well as the Medic-alert console. With this option they provide a feature in which they test your system monthly so that they could hear you in case of a medical emergency. I had to use them on one occasion in which they had to contact emergency services to get me an ambulance to get to the hospital. They literally saved my life."

"We had new windows installed, scheduled an appointment the next day to reinstall our sensors. ADT technician Matt **, the most courteous and knowledgeable technician I've ever met...
also reviewed and checked our entire system, ensuring that every facet of it operated correctly. When he finished, he thoroughly briefed us. If I ever need an ADT technician again, I want Matt **! Great ADT Service!"

Burglary Monitoring
Our home alarm security systems are constantly monitoring to ensure that once a burglary alarm is received at a Customer Monitoring Center, a trained ADT professional will notify you and first responders quickly.
Fire and Smoke Monitoring
When a fire and smoke detector in one of our home security systems is received, a trained ADT professional will notify you and your local fire department as quickly as possible.
Medical Alert Monitoring
Never feel alone again with ADT medical alert monitoring in our home alarm security systems. Push a button to be connected to a trained ADT professional through the two-way voice intercom system. If assistance is needed, this professional will contact the appropriate emergency response services.
Security Camera Systems
With an ADT wireless home security camera system, you can do more than monitor your home security remotely — you can manage your life. For example, looking in on the cable repairman from your office.
Carbon Monoxide Monitoring
A carbon monoxide (CO) leak can spell serious harm for you and your family since it can be impossible to detect without a warning device. Make your home a safer place with CO monitoring services available with most ADT home security systems.
