## Long description

Ajax 39055 is a white curtain-style outdoor motion detector designed to monitor narrow zones such as windows, doors and perimeters. Built for exterior installations, the detector uses a focused detection beam to reduce false alarms and provides targeted monitoring of entry points and façades. The device integrates with Ajax security systems and is intended to protect against unauthorised access across specific linear areas.
Advantages
The curtain motion detector offers precise detection along a narrow coverage zone, minimising activation from irrelevant movement. Its weather-resistant design allows operation in a wide temperature range from −25°С to +60°С. Compact dimensions (174 × 123 × 88 mm) make the unit unobtrusive while enabling flexible placement on walls or near openings. Wireless operation simplifies installation and integration into existing Ajax setups.
