An overview of contact sensors:

  • Contact sensors play a vital role in protecting your home by triggering your alarm when activated. 
  • Mount contact sensors with adhesive for a drill-free setup, then pair them with your favorite smart home app.
Contact sensors adhere to doors and windows and alert homeowners of intrusions or break-ins. Available in wired or wireless applications, they activate when sensors are separated—triggering everything from alerts to alarms.

Integration with a mobile security app from Alarm.com makes all this possible, from the convenience of your smartphone, tablet, or computer. 

Professionally installed contact sensors enhance your convenience, save money on energy bills, and give your home more comprehensive security. 


How Contact Sensors Function 

Contact sensors consist of a sensor and a magnet. When attached to entry and exit points, such as windows and doors,  they can alert homeowners when triggered. 

When the sensor recognizes separation, it transmits a signal, in real time, creating a notification in your security app and/or the central monitoring stationThis can signal a wide range of smart home functions depending on which rules you have set up.

For example: A family room light can be turned on if a specific sensor is activated.

Additionally, with a contact sensor attached to your refrigerator door, you can be notified when it has been left open for more than a minute, helping you reduce energy waste (and spoiled food). 

Notably, sensors are available in various wireless or wired configurations. It’s best to place sensors as out of reach as possible.

Depending on your property, coverage areas, and personal needs, various sensor types are available and compatible with most security apps and smart home hubs.
