Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Indoor intrusion detection in residential or small commercial spaces where pet-immune PIR coverage and long-range 868MHz wireless signaling are needed.
Pet immunity helps reduce false alarms from animals so monitoring stays focused on genuine intrusion events.
Frequency hopping and two-way AES128 encrypted communication support reliable signaling over long distances in open space.
Low battery alarms and signal strength detection let you plan maintenance before a detector goes offline.
