PIRAMID

Dual Technology Detector

Radar function for precise detection zone length setting
Centralization of the alarms with the MAXIBUS UNIVERSAL via the deported module 8 inputs (MI8)
Bluetooth configuration on Smartphone

Principle

The new PIRAMID detectors are a high performance intrusion volumetric detection system at the cutting edge of current technology. The reliability of the product by the combination of two technologies is provided by a passive infrared sensor (PIR) and a Doppler microwave antenna. The alarm will only be triggered if the two technologies simultaneously detect an intrusion.

PIRAMID detectors are very easy to set up. Via a secure application on smartphone or tablet, if the detector is difficult to access, the setting can be done locally, wirelessly.
The embedded CONNECT technology makes it possible to put several PIRAMID detectors in radio or wired network to centralize the alarm information on the MAXIBUS UNIVERSAL.

It is also possible to retrieve the alarm information thanks to the on-board dry contact outputs.

PIRAMID detectors can be used in a wide variety of environments to protect specific assets or strategic locations: passageway, building entrance, pre-defined area.

Example: loading dock, hazardous storage area …

Do not install the detector on a surface exposed to strong vibrations. It must be installed on a wall or a solid post. In the case of mounting on a building with a metal surface, provide a vibration-resistant support.
Orient the detector down so that its cover stops at ground level in the required protection zone. Depending on the detector model, the PIRAMID provides up to 30m range detection regardless of weather conditions.
Do not install the detector under an eave without a gutter. In case of heavy rain, the flow of water directly in front of the detector can cause nuisance alarms.

Dual technology detectors combine a passive infrared (PIR) sensor with a Doppler microwave sensor. SORHEA has combined these two technologies to develop reliable detection solutions.

Passive infrared detection is based on an analysis of the temperature emitted in the monitored area. Indeed, an intruder has a body temperature that strongly contrasts with the rest of the environment. The microwave antenna consists of a 10,5 GHz transmitter (in K-band) and a Doppler receiver, which detects the signal variations caused by the passage of an object in the lobe. The combination of these two technologies provides a reliable and powerful solution by forming an immaterial curtain of detection or an immaterial lobe (depending on the sensor model).

If each technology can be sensitive to certain disturbances (sensitivity of the PIR to the reflection of the heat and the Doppler to the movements of the water), the combination of the two becomes effective since the advantages of each technology cancel the disadvantages of the other. To trigger an alarm, both technologies must detect an intrusion.
