The JVA VM2 is a Perimeter Intrusion Detection System utilizing Microphonic Cable. The VM2 (PTE0342) is designed to monitor one or two zones of Microphonic (acoustic) cable to enable the detection of an attempted breach of a perimeter by detection of the noise and vibrations created by unauthorized access or vandalism. The monitoring cables may be buried to detect digging, atached to a fence or placed inside a wall, roof or ﬂoor etc. to detect illegal activity.
The VM2, coupled with correctly installed cable creates a fully monitored and zoned intrusion detection system. The VM2 has adjustable threshold and me parameters that allows the installer to tune the system to diﬀerent ate between an intrusion attempt and normal environmental sounds vibrations. The VM2 complements JVA's range of security electric fence energizers and monitors.
