Custom Made
Pyro-Electric Sensor

Orisec know that the pyro is the single most important component in PIR design. Our pyros are custom made to our exacting standards, specifically for use in our intruder detectors. This gives the best detection pick-up coupled with unsurpassed false alarm immunity from sunlight, RF and electrical interference.

Custom Made
Spherical Fresnel Lenses

Not only do Orisec lenses adhere to the ideal spherical shape, they also feature micro-fine Fresnel grooves. These dramatically improve the focussing of each zone to give clear, crisp signals which improve detection pickup and help reduce false alarms.

Moreover, the Orisec multi-height optics enable the detectors to be mounted between 1.8m and 3.1m without having to adjust the PCB position.


Elevate your brand visibility and exposure by ensuring your logo is displayed on all your detectors. Our experienced & professional in-house printing facility can print your branding watermarked or in full colour.

No Minimum Order Quantity.

Multi Height Optics with True Creep Zones

Orisec’s unique Multi Height Optics with true creep zones enable mounting anywhere between 1.8m and 3.1m with no adjustment necessary or compromise in detection performance.

Sealed Optics

Sealed optics prevent bugs and dust from entering the housing, reducing false alarms and maximising reliability.

Digital Signal Processing

Orisec’s advanced digital signal processing gives the very best intruder detection combined with false alarm and RFI immunity right up to 2.7GHz.
