DualCurtain Outdoor Jeweller is a wireless outdoor “curtain” motion detector featuring two independent PIR sensors on each side — detection zones reach up to 15 m on each side (up to 30 m total). The alarm is triggered only when both sensors on one side detect motion, helping to minimize false alarms caused by animals or environmental interference. The device offers close-range detection, vertical beam tilt adjustment, anti-masking protection, and radio communication up to 1,700 m with an Ajax hub via the Jeweller protocol. Thanks to energy-efficient operation, it can run on batteries for up to 4 years. Available in white.
