ADT door alarms
Door security devices are the first line of protection for your home. And with all the comings and goings, there’s plenty of room for error. Take precautions against accidental unlocked doors by helping secure your home with ADT door sensors.
All-over door alarm systems
Open and close alerts
When your system is armed, you’ll hear an electronic chirp or voice alert to let you know every time a door is opened or closed.
If an intruder tries to break into your home while the system is armed, they’ll hear your system’s high-decibel alarm, letting them know they picked the wrong house.
