Ajax Curtain Outdoor Jeweller – Wireless Perimeter Motion Detector
Ajax Curtain Outdoor Jeweller – Wireless Perimeter Motion Detector
The Ajax Curtain Outdoor Jeweller is a wireless dual-technology perimeter detector built for exterior installation — combining two PIR sensors with a K-band microwave sensor to deliver near-zero false alarms in real outdoor conditions.
Protect your perimeter without alarming your backyard. Adjustable range, pet immunity, and the SmartDetect algorithm mean the Curtain Outdoor responds to people — not wind, animals, or thermal shifts.

🧠 SmartDetect — Ajax's Outdoor False Alarm Filter
When armed, SmartDetect continuously analyzes data from both PIR sensors: IR radiation intensity, thermal spot size, movement speed, and time in the detection zone. It instantly identifies false alarm markers — swaying branches, passing headlights, thermal shifts — and ignores them. Only confirmed human movement triggers an alarm. Temperature compensation adjusts the baseline in real time so detection stays accurate even when ambient temperature approaches body temperature.
