新型防入侵保安磁场传感器

A New magnetic field sensor used for the purpose of security outdoor perimeter intrusion dedection

采用泄漏电缆的磁场扰动设计的新型保安防入侵传感器。隐蔽、抗干扰能力强、造价低,且能运用于地形、地貌复杂的场合,对环境的适应性强,还可探测到入侵者在周界上的确定地段,因此,这是一种很有前途、欧美各国近年来竞相发展、公认是潜在市场很大的新型保安传感器。

This new magnetic field sensor follows their H field system, consisting of buried cables designed to 'leak' radio frequency energy and to detect intruders by sensing the effect of energy reflected from an intruder walking over the cables. They possess an inherently low false alarm rate, being immune to seismic and acoustic changes, as well as wind, snow and ice.
