Infrared Barriers


Infrared Barriers

SORHEA’s infrared barriers use active infrared technology, such as transmitting and receiving a beam of light. Barriers are used to create a true intangible and invisible wall of perception.

Active infrared barriers consist of transmitter cells that emit invisible active infrared light beams and receptor cells that collect and analyse the beams received.

Tag: Barrier

By combining these two cell types, active infrared barriers form an immaterial wall. When one or more beams are interrupted, the system triggers an alarm. The columns are positioned facing one another and are installed along the perimeter of the site to be protected.


  • Time Saving and Easy COnfiguration

  • High Reliability of D.S.D ( Dynamic-Scan-Detection)

  • High Detection Power: thanks to the light curtain renforcement

  • Very Low Unwanted Alarms Rate: thanks to the three detection modes

    D.S.D technology enables an independent management of the cells :

    DYNAMIC: cell by cell infrared scan
    SCAN: 1000 beams / second
    DETECTION: improved opacity of the detection wall

    Only our D.S.D technology allows the management of up to 18 cells per direction and proposes various detection modes :

    -Cutting of one infrared cell
    -Cutting of two adjacent infrared cells
    -Cutting of three adjacent infrared cells
    D.S.D technology offers an alignment system of cells facilitated by a led and a buzzer, which confirm the alignment quality of the beams.

Our cells can manage the maximum number of cells per column. Our multiplexing creates a very highdensity infrared wall that cannot be breached. Only our multiplexing technology can manage up to 18 cells per direction and offers several detection modes:

  • Alarm on interruption of an infrared cell (mono-detection)
  • Alarm on interruption of two adjacent infrared cells (dual-direction)
  • Alarm on interruption of three adjacent infrared cells (tri-direction)

The simultaneous combination of detection modes (multi-mode detection) allows for intruder size fi ltering. Each detection mode has its own confi gurable response time from 40 to 800 ms.
In addition, the time delay alarm of the detection modes allows for intruder speed of movement fi ltering. A specifi c delay can be applied to the bottom beam to detect crawling as well as fi ltering the passage of birds and small animals.
The combination of these 2 fi lters (intruder size and speed) give our infrared barriers unrivalled reliability.
