Ajax Systems MotionProtect Plus

The Ajax MotionProtect Plus is a professional-grade wireless motion detector that combines passive infrared (PIR) and microwave sensing to deliver exceptional intrusion detection with minimal false alarms. Its dual-technology design verifies alerts using two independent channels, ensuring reliable performance even in challenging environments. With a detection range of up to 12 meters and pet immunity up to 20 kg, it is ideal for securing homes, offices, and commercial premises.

Advantages

Dual PIR and microwave sensors work together to filter out false triggers from pets, drafts, or moving objects. The SmartDetect algorithm adjusts sensitivity automatically, while jamming detection and tamper protection keep the device secure against sabotage. Battery life extends up to 5 years on a single CR123A cell, and the Ajax Jeweller radio protocol provides a robust wireless link with a range of up to 1200 meters in open space.
