AJAX Curtain Outdoor Jeweller
Curtain Outdoor Jeweller provides exceptional perimeter protection with dual-technology motion detection. Two PIR sensors combined with a K-band microwave sensor virtually eliminate false alarms. The narrow 8° horizontal beam creates an invisible curtain barrier up to 12m long – perfect for protecting doors, windows, and entry points. The anti-masking system detects sabotage attempts, while pet immunity mode ignores animals up to 100cm tall. IP55-rated for outdoor use, it operates reliably from -25°C to +60°C.
