The device is powered by a high-efficiency CR123A battery that provides an impressive lifespan of up to five years, drastically reducing the need for frequent maintenance.

Suitable for
Monitoring entry points such as main doors and back doors

Temporary deactivation for frequent access areas
This sensor may not be suitable for environments where there is significant physical obstruction between the sensor and the HomeBase, as this can reduce the effective wireless range. It is also not intended for outdoor use in extreme weather conditions without appropriate protection, as it is designed primarily for indoor residential security applications.
