Key features of Reliant door & window sensors
Professional 24/7 monitoring
- These door and window sensors are designed to work with all the Reliant home security system packages. Our 5-star rated monitoring service is here for you whenever an alarm sounds.
Integrated monitoring
- Use with other home automation and security devices. For instance, if a contact sensor indicates a door or window left open, the thermostat will automatically set back to save energy until the door is closed again.
Multiple users
- The sensors are small, simple and unobtrusive and can be used in tight spots like freezer doors, medicine cabinets and gun safes.
Professional installation
- Reliant’s professional technicians can install your door and window sensors and test them to make sure they're fully operational.
