Ajax MotionProtect Outdoor Jeweller

Wireless outdoor motion detector built for perimeter protection. Combines dual-PIR sensors, anti-masking, weather resistance, and secure Jeweller wireless communication to reliably detect intruders while filtering out false alarms. Ideal for gates, fencing, gardens, walls, windows and other outdoor vulnerable zones. cctvhut.co.uk+3Ajax Systems+3Ajax Systems+3

Key Features

• Dual PIR Sensing + Smart Algorithms
  Two infrared sensors monitor overlapping zones. Uses the LISA algorithm (correlation + spectral analysis) to verify motion between both sensors to reduce false alarms (e.g. heat sources, small animals). Ajax Systems+1

• Adjustable Detection Range
  Detection distance is adjustable (from ~3 m up to ~15 m) via built-in control, allowing calibration for different installation scenarios. Ajax Systems+1

• Anti-Masking & Tamper Protection
  Anti-masking sensors detect when lenses are blocked, painted or covered. Tamper switch triggers if device is removed from its mounting plate (SmartBracket). Ajax Systems+1

• Weather-Resistant Build
  Operating range from −25°C to +60°C, protected from dust and water jets (IP55). Can be fitted with optional hood to protect anti-masking sensors from rain/snow. Ajax Systems+1

• Pet Immunity
  Does not respond to animals up to ≈ 80 cm in height, when properly installed (height & angle). Note: height of installation matters for pet immunity to work well. Ajax Systems Support+1

• Reliable Wireless Communication (Jeweller Protocol)
  Two-way encrypted communication, authentication, frequency hopping, strong anti-spoof protections. Radio range up to 1,700 meters in open space; alarm delivery in < 0.15 seconds. Ajax Systems+2Ajax Systems+2

• Long Battery Life & Optional External Power
  Supplied with two pre-installed CR123A batteries; up to 5 years of service under typical use. Also option to use external power (5-28 V DC) for certain installations. Ajax Systems+2Ajax Systems+2

Recommended Applications & Installation Tips

• Ideal for outdoor perimeter lines: gates, fences, walls, windows where you want to detect intrusion early.

• Mount height should be between about 0.8 m to 1.3 m above ground for effective pet immunity and proper detection performance. cctvhut.co.uk+1

• When possible use the hood accessory to shield anti-masking sensors from rain/snow, improving reliability in harsh weather. Ajax Systems

• Adjust detection distance to the environment: reduce range when there are bushes, moving foliage or reflecting surfaces nearby.

• Ensure proper signal strength to hub; in environments with obstacles, use signal repeaters or choose installation sites with minimal obstruction.
