"I've had my ADT system since I moved into my new home. I love the peace of mind it gives me both when I am at home and away. I accidentally set off the panic alarm recently and ADT was on the phone before I could even get to the box...

to deactivate it! I continue to be amazed at how reasonably priced the system is. Then again, you can't put a price on a sense of security."

"The technician was very thorough and efficient. He took extra measures by ensuring that I knew how all the equipment worked and how to navigate through the Pulse application.

Carlos was his name I think; very professional! I will definitely recommend ADT to family and friends."

"I had ADT and I love them. They're always there to answer your call. If they needed to come do anything, which wasn't very often, they did come. And if it was something covered, they wouldn't charge for it.

Because they had come, we had to change the door, have it made and put in. They had to come and redo that, but they didn't charge anything. I'm very well pleased with ADT. The only reason I left them was that I moved. With age, I downsized from a house to an apartment with a 24-hour doorman and a garage walk right into the building, so we no longer have security systems in individual apartments. Otherwise, I would have still been with ADT."

With ADT smart home automation you never have to worry about forgetting to turn off appliances, setting the alarm, or walking into a dark house. ADT home security systems installed in Houston offer advanced features when paired with ADT Command - our cutting edge home automation service. The ADT Control smart home mobile app gives you full access to your security alarm and smart home equipment, whether you're in Houston or anywhere else life may take you.

Our home automation service is matched with our dedication to giving you the fastest response when your security alarm is triggered.

Keep an eye on your home, pets and loved ones with trust-worthy security cameras and surveillance systems. Your surveillance system will automatically start recording if your alarm is ever triggered, and notifications are pushed to your smartphone or tablet. Not only do these investments provide peace of mind, they can also assist with discounts on your homeowners insurance.

Easily maintain control of your home and improve your quality of life with this convenient technology. This provides a simple solution for monitoring all aspects of your home, regardless of where life takes you, from safety (by seeing who is at your front door) to energy consumption. Smart home systems are great for all living situations whether you live in a house, condo, apartment or mobile home.

Get smarter home security with remote control of your system and more. 

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.
