"Occasionally I forget that I put my alarm on and make it go off. I'm always amazed by the quick response. It really makes me feel safe. And they're always very courteous and professional even though...
I'm the one that messed up. I really appreciate ADT and the price is so reasonable."

"We just bought our home and chose ADT to provide our security service. Due to a delay in our closing, the original scheduled appointment for installation was delayed for a week, but they were very understanding.
Upon installation, we were guided through the use of the system and we discussed some external safety issues as well. Very professional and courteous! Highly recommended for peace of mind!"

"We have peace of mind since ADT is protecting our home. The system is very easy to use and we feel so protected both when home and away.
Before ADT we had experienced several attempted break-ins as well as one robbery where our guns were taken. Since ADT no break-ins just peace."

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.
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.
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.
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.
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.
