Two-zone triboelectric security detector "Gyurza-2K"

The detector is designed to protect territories from unauthorised entry through the perimeter fence by the following methods:
- climbing without improvised means;
- climbing with the help of an extension ladder with support on the fence;
- breaking the integrity of the fence elements by disassembling the fence web, forming a passage by "biting" or "sawing" the fence web, including with or without bending a part of the fence web, regardless of the number of "bites" or "sawing" of the fence web elements and time interval;
- digging under the barrier with mechanical impact on the buried part of the barrier;
- dismantling of the sensitive element (SE) and violation of its integrity.
