Description

Wireless Triple-Tech Detector performs high precision detection using
PIR, microwave detection technology, optical technology and intelligent
algorithms. It also eliminates interference caused by small animals, the
ambient temperature and changes in the light to ensure that the detector accurately recognizes when people move, even in complex environments. When combined with the camera module, its capabilities expand
allowing you to both monitor your scene through videos and images,
and check alarms in real time. You also receive alarm notifications when
alarms are triggered, so that you can stay up to date on the situation of
your site.
