Engineered for Maximum Performance to Reduce False Alarms
Custom Pyro-Electric Sensors
Unlike standard sensors in many detectors, Orisec’s pyro-electric sensors are designed specifically for security applications. These sensors help reduce false alarms from sunlight, electrical interference, and radio frequencies, ensuring the system only activates when an actual intrusion is detected.
Patented Signal Processing Technology
Many PIR detectors rely on simple signal amplitude analysis, which can lead to false triggers. Orisec detectors use multiple patented signal processing techniques that analyse the entire shape of incoming signals, improving accuracy and response speed while significantly reducing false alarms.
Superior Optical Design
Orisec detectors incorporate spherical Fresnel lenses with micro-fine grooves for enhanced detection performance. Unlike standard flat or cylindrical lenses, which can compromise accuracy, this design ensures:
- Clear and consistent detection across all zones
- Minimised false alarms due to better optical focus
- Flexible mounting heights from 1.8m to 3.1m without adjustments
