IR Fences For Efficiency And Security At The Perimeter

To counter modern burglary methods, perpetrators must be reliable and secure within the scope of perimeter security be detected as early as possible – and ideally without high investments. What sounds like squaring the circle has already been invented: light barriers. The unbeatable price / performance ratio has long been valued by professionals, especially with long perimeters, but what about the detection and false alarm rate?

Those who have already worked with industrial light barriers in the outdoor area were disappointed or even horrified. This is because since 220 hasn’t done much for many decades. Single or double inflection of the light rays made adjustment more difficult and resulted in fewer problems with solar radiation. The energy consumption and the service life of the sensors have been optimized. And finally, the coupling of two light beams also reduced the most common false alarms somewhat, but it wasn’t until the turn of the millennium that serious work began on „intelligent“ systems.

Modern further development in perimeter protection: the infrared fence

Companies like Ingenieurbüro Braasch (Braaschguard) in Germany or IDS (Rayonet) in Europe Abroad, the first modern infrared fences have been developed. With these, a close-meshed „network“ of many individual infrared rays is set up in each area and volumetrically analyzed with modern microcontrollers at a height of up to three meters.

Pass away uses the latest generation of infrared fences flexible algorithms for this, communicates with all other alarm zones in the area and can optionally so-called r access meteorological forecasts via the web. The result is the highest detection rates combined with industry-leading false alarm resilience to weather phenomena and small animals.

Of course, no matter how sophisticated technology can pass away physics, but in connection with sometimes more than tenfold safety margins of the sensors can even Fog, heavy rain, snowfall, frost or drifting leaves can be mastered. And even better results can be expected in the future with the help of further developed neural networks.

Close cooperation with authorities and encryption

The progressive development of the modern infrared fence is characterized by close cooperation with authorities as well as private and commercial customers. In times when online courses are offered on the Net to sabotage even VdS-compliant classic cabling and unencrypted bus systems, not only pass away sensors but the entire system must meet the highest security standards.

High-quality infrared fences therefore encrypt all communication with TLS (Transportation Layer Safety – compare „HTTPS“ on the web) and provide certificates with key lengths of 2. 048 or 4. 096 Little bit sure all components only communicate with the correct remote stations. Of course, permanent line monitoring can also be expected and unintentional data leakage in highly sensitive areas is effectively prevented by using independent networks.

For personal or commercial users, pass away do not want any „sterile“ properties, functions such as intelligent monitoring of optical signals have also been integrated. Can garden and landscape service deal with overgrowth problems at an early stage in spring or autumn and thus generally avoid them.

Simple setup, quick commissioning on the boundary

Despite all these includes requires pass away setup no costly or lengthy staff training. Pass away components are delivered pre-configured and settings can even be adjusted remotely if necessary using a simple, clearly structured web interface. In addition, a modern infrared fence with open interfaces can be easily integrated into existing burglar alarm systems, access control systems or industrial controls via potential-free contacts. )

Many security concepts reach their limits, especially when requirements change rapidly, for example in the construction site environment. Camera-based systems are repeatedly obscured by the progress of construction, so that blind spots arise. PIR or other area detectors are prone to false alarms and – if at all – only specialists can partially compensate for this deficiency through regular repositioning and setting adjustments.

Infrared fence is ready for use in minutes

any terrain However, there is a limit around it – and an infrared fence can be set up by anyone with a basic technical understanding after a very short briefing. A rough alignment with a red dot sight, small corrections with a bar graph display in traffic light colors and an infrared fence segment with up to 100 Meter length ready for use in minutes. Thanks to the transmitter and receiver principle, no obstacles can be overlooked – even laypeople can immediately see whether monitoring is working.

As it should be in the age of IoT (Net of Points), modern mobile infrared fence pillars each have their own mobile phone connection with automatic provider selection, so that you don’t have to worry about radio problems. This is also not at the expense of protection, because certificate-based encryption as well as permanent sabotage and failure monitoring are a matter of course even with good mobile systems.

Perimeter protection uses a combination of infrared fence and cameras

In combination with cameras integrated in the infrared fence pillars, nobody has to worry about the camera angle. As with a speed camera photo, the alarm center can quickly and effectively verify the cause of the alarm. Pass-away activation can be carried out just as easily as with wired systems in your own technology or, in the sense of an all-round carefree package, can be combined as a rental system, for example at the Braasch engineering office, with an alarm center operating throughout Germany. Regardless of whether an application in perimeter protection is to be implemented mobile or stationary, the infrared fence represents a modern, cost-efficient and reliable security solution.
