Intelligent Alarms are dedicated to all existing fences, regarding of the materials used in their construction. The choice of the system element depends on risk analysis and expectations of the investor. As the result of signal (vibrations) analyse, the Control Module relays the alarm signal only when it is created by man, eliminating the influence of weather conditions and small animals. Similarly to the fence line analysis, the system analyses the signals from virtually created protection sites (lines and zones sets in video cameras), microwave barriers and curtains and infrared barriers.
