Ajax Superior MotionProtect G3 Fibra Black — Grade 3 Motion Detector

Professional Grade 3 High-Security Ajax Superior MotionProtect G3 Fibra White Wired Motion Detector with Advanced Anti-masking and Triple Tamper Switches

The 4 MP Black / White Ajax Superior MotionProtect G3 Fibra in black is a high-security wired motion detector engineered specifically for high-risk applications including financial institutions, jewelry stores, critical infrastructure, government buildings, and luxury retail environments. Designed in strict compliance with rigorous EN 50131 Grade 3 European security standards, this unit provides maximum defense against sophisticated bypass or physical sabotage attempts by skilled intruders.

Featuring proprietary mirror optics and a high-sensitivity pyroelectric PIR sensor, the detector monitors spaces up to 15 meters at a 90° horizontal viewing angle. Its advanced SmartDetect processing algorithm dynamically compensates for temperature changes while filtering out non-threat heat sources like hot air currents, ensuring accurate human motion detection without false alarms. Furthermore, it features a minimized blind zone capable of detecting crawling intruders just 50 cm below the device base.

Advanced Tamper Resistance, Fibra Technology, and Professional Deployment

To satisfy demanding Grade 3 requirements, the Superior MotionProtect G3 Fibra includes an active IR anti-masking system that constantly monitors the lens, immediately alerting the system to attempts to obscure, cover, or spray paint over the optics—even when the system is disarmed. The heavy-duty housing incorporates three physical tamper buttons: two rear switches for wall/SmartBracket removal detection, and a third switch protecting the enclosure latch.

Communication with the hub is handled via the proprietary wired Fibra protocol, ensuring instantaneous alarm delivery, dynamic key block encryption, short-circuit protection, and bus line support up to 2000 meters.
