Perimeter protection

How large areas are protected?

The protection of large open areas is a specific task that perimeter security systems deal with. They aim to prevent breaking into the protected perimeter by detecting the potential intruder and sending real-time information on the infringement to the monitoring center. The detection can be done in different ways and the specific conditions of the project determine which one is the most suitable.

Although microwave barriers or specialized PIR sensors for perimeter protection are most commonly used, the sensor cable for vibration detection is an indispensable solution for fenced sites where high security is sought with a minimum of false alarms. If the site does not have a fence, an invisible perimeter protection can be built using sensors that detect changes in the electromagnetic field generated by underground cables.

Increasingly, perimeter protection tasks are being solved with the help of video surveillance systems, using software and cameras with intelligent functions - "crossing a virtual line" or "entering a protected area".

Interim protection for special events

Special attention should be paid to thermal cameras, which cover a large area and are effective even in extreme weather conditions (snow, rain, smoke, fog, complete darkness). The combination of different detection methods makes it possible to create individual solutions that meet the specifics of the particular object, are reliable and work flawlessly in all weather conditions.

For special occasions such as concerts, sports, political or other events, it is necessary to provide temporary protection around the perimeter. We can offer you a solution to this problem with microwave barriers. This system does not need many complex accessories.

Installation is relatively quick and only a power supply, a calibration tool and a monitoring computer are required. The system works reliably till the end of the period required, after which it is easily dismantled and ready to be used for other events.

It is important to note that perimeter protection systems reduce the cost of security guards, because the immediate and accurate localization of violations within a perimeter of several kilometers, makes it possible to send the guard to the right place at the right time. Thus, security is effective even with limited staff.
