TECHNOLOGY FILE OPERATING PRINCIPLE With more than 37 years’ experience, we have been able to perfect our own technology: multiplexing. This makes our infrared columns the most reliable on the market. Multiplexing allows for independent cell management. It consists of managing the cells individually with a scan of 1000 beams per second. More than 35 years’ experience in active infrared perimeter detection Highly reliable active infrared technology by SORHEA thanks to our Multiplexing :- simultaneous multi-mode detection- time-delay alarm Optimised installation and maintenance time and easy operation: alignment tool WHY SORHEA’S TECHNOLOGY? SORHEA INFRARED IS HIGHLY RELIABLE: with more than 35 years of experience HIGH POWER OF DETECTION with the reinforced virtual wall VERY LOW UNWANTED ALARM RATE: with multi-mode simultaneous detection EASY AND TIME SAVING confi guration and maintenance WHY OUR SOLUTION? discover discover The different detection modes that can be configured on our barriers ensure a high level of detection reliability. These different detection modes (timecontrolled dual-detection, mono-detection, timecontrolled lower beam mono-detection) can function simultaneously, making it possible to filter out unwanted alarms (birds,animals, etc.). 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 The simultaneous combination of detection modes (multi-mode detection) allows for intruder size filtering. 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 specific delay can be applied to the bottom beam to detect crawling as well as filtering the passage of birds and small animals. The combination of these 2 filters (intruder size and speed) give our infrared barriers unrivalled reliability.
