Sorhea offers:

Infrared barriers

SORHEA’s infrared barriers use active infrared technology, i.e. transmission and reception of a light beam. The barriers are used to create a real immaterial and invisible detection wall.

Active infrared barriers

Active infrared barriers are composed of :

  • TRANSMITTER CELLS that emit beams of invisible infrared light.
  • RECEIVER CELLS that detect the beams and analyze weather they are correctly received.

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.

To meet all of your specialized needs, we have developed four housings that can be used with all of our products.

Shock detectors

SORHEA’s shock detection cables are equipped with an accelerometer. This type of sensor detects the variations in movement of an object according to 3 axes, comparing them to a pre-set zero point.

The sensor has the special feature of making the entire fence panel sensitive to cuts, climbing or tearing-down because every intrusion-induced vibration (not vibrations caused by wind) is detected by the sensor.

SHOCK DETECTION CABLES

Shock detection cables consist of:

  • SENSORS installed on fencing panels
  • connected to a CONTROL UNIT.

Attempts to climb over or cut the lines are detected by the sensors and transmitted to the control units which then trigger an alarm.
The shock detection cables create an intrusion detection system that utilises the existing fencing at the site to be secured.

Detector fences

Detector fences are a patented very high-security solution. The first function of these products is to physically prevent an intrusion.

The fence panels mounted on the poles consist of two plates (with electric current running through each of them), isolated from each other. Any cutting or tearing-down attempts creates a short-circuit and triggers an alarm.

The technology strengths:

  • No false alarm possible
  • Provides physical (anti-intrusion) and electronic (detection) protection
  • Creation of active cages to protect highly secured access and small zones

Fences and outrigger detectors are perimeter protection systems whose main function is to physically prevent intrusions. Active fences are composed of detector panels that generate an alarm when someone tries to cut through them or tear them down. Outrigger detectors transmit an alarm information when an intruder tries to climb over a fence, a gate or a wall.

Dual technology detectors

The dual-technology detectors associate a passive infrared (PIR) sensor with a microwave sensor with Doppler effect. The passive infrared detector detects temperature variations in its detection field during an intrusion.

The Doppler detector uses a microwave transmitter and receiver antenna that transmits a pulse and analyses the signal reflected by the environment. The frequency differences between the signal transmitted and the signal received provide information about the moving objects in the detection area.

Video analysis

The objective is to capture any intruder in the monitored location regardless of environmental conditions while filtering false alarms.

Thanks to our integration with VMS, CMS, PSIM… the video of the alarm is sent instantly to alarm receiving centers or monitoring stations enabling the right decision to arrest the intruder immediately.

Technology  points:

  • Reliable and powerful solution: Omission-free reliable Detection: Systematic detection whatever the environment with almost no false alarms.
  • Immediate alarm qualification by alarm receiving centers or central control stations.
  • End-to-End assistance support: recommendations and expert advices, implementation assistance and training by our expert team.

Integration

We have developed Maxibus Universel, a hub that centralizes the alarm information of all our products as well as third-party products. It allows you to connect to the various operating systems of the alarms.
(VMS, GTC, alarm control units, hypervisor). All our products are connected via a network on this hub, either natively, or via 8 INPUTS REMOTE MODULE (MI8), our radio or wired communication module. Maxibus Universel is interfaced with the alarm operating systems : via relay output (dry contacts), via ModBus protocol (RTU or TCP), via the Smart Device software, our VMS gateway (Genetec, Seetec, Milestone).

Your  points:

  • The interface is the same regardless of the SORHEA product connected to the hub.
