Knowledge is Power with the
ADT-monitored Door and Window Sensors
Door and Window Sensor

Knowing who gets in or out is key to keeping your home safe. Monitoring your house's entry points is the backbone of a good system, and ADT-monitored door and window sensors ensure you know anytime someone enters or exits your house.

Our door sensors and window sensors feature a slim profile and operate wirelessly, eliminating ugly, cumbersome cords and holes drilled into walls. The magnetic reed switch operation allows a small gap between the sensor pieces, so doors and windows can open naturally.


Peace of Mind You Can Count On with Monitored Window and Door Sensors


Monitored door and window sensors immediately alert you if any of your doors or windows have been opened. Want to know when your teenager arrives home from school, or when the pet sitter arrives while you’re on vacation? With the ADT Mobile App, you can be alerted anytime an entry point has been breached. You also receive 24/7 protection. The ADT monitoring centers will notify you of any activity while your system is armed.

Frequently Asked Questions

Q: Do I have to install it?
A: No. Protect Your Home’s professional installers set up your entire system for you, including door and window sensors, and take the time to show you how to operate each piece before they leave. They’ll make sure your monitoring system is working before they leave the home.
Q: Do these sensors require wires running to every window and door?
A: No. Wireless technology and long lasting lithium battery technology mean you don’t have to worry about wires being strung throughout your house, either inside or outside the walls.
Q: What notification options do I have for the door and window sensors?
A: You can set your security panel to chime when one of these sensors is triggered or you can silence alerts. If you upgrade to a package that includes the ADT app, you can set the app to alert you and send text messages any time a sensor is triggered when you are away and view each sensor to see if they are opened or closed even while on the go.
