Ajax Curtain Outdoor Jeweller wireless outdoor motion curtain detector dual PIR + microwave detection 8–12 m 868 MHz Jeweller perimeter protection antimasking battery powered ~3 years hub range up to 1700 m white

Ajax Curtain Outdoor Jeweller is a wireless outdoor curtain motion detector designed for perimeter protection, for example along fences, windows, doors or gates. It uses dual PIR and microwave sensing technology to accurately detect human movement within a long, narrow zone up to 8–12 m, and Jeweller two-way RF wireless communication with up to 1700 m radio range for stable alarm transmission.

Key Advantages

• Dual PIR + K-band microwave technology → accurate motion detection with a very low number of false alarms

• Narrow “curtain” detection zone → effective perimeter protection along walls, doors and fences

• Adjustable detection range (8–12 m) → configurable to the property layout

• Jeweller two-way RF wireless protocol → secure and fast data transmission to the hub up to 1700 m

• Anti-masking system → detects attempts to block or mask the sensors

• Pet immunity → can ignore small pet movement, reducing false alarms

• Up to 3 years battery autonomy → long operation without frequent battery replacement

• Wide operating temperature range → reliable operation from −25 °C to +60 °C
