These sensors detect infrared heat signatures and then emit a wireless signal to a central alarm system, such as our JC-G02 (which can track up to 99 wireless sensors). This sensor does not emit an audible sound that can be heard.
Use several of these sensors to establish "zones" of coverage, and your central alarm system will then alert you when a zone has activity -- you can then view the area if you have surveillance cameras established, or be alert to take other action.
