The VIPER is a new generation Vibration perimeter fence sensor system designed to handle all aspects of perimeter protection. It upgrades any existing fence to the status of an electric barrier with an exceptional detection resolution of +/- 10 meters.
Wherever perimeter protection and intrusion detection are required, the VIPER provides the utmost with a system that is easy to install, operate and maintain. The long life sensor units are easily attached to the fence at approximately 3 meter intervals and are highly immune to extraneous environmental factors.
The VIPER technology is approved by the Israeli army technological unit
for protection of borders, military camps and top secret sites.
PRINCIPLE OF OPERATION:
The perimeter intrusion detection principle of the VIPER is based on "reflected wave technology" that works in a similar way to radar.
Each perimeter control unit (PCU) transmits electric pulses into the sensor line. When an intrusion attempt occurs along the perimeter, it will be detected by a reflected wave from the nearest sensors. The time delay between the transmitted and the reflected wave will determine the location of the event within +/- 10 meters resolution.
This "RADAR-LIKE" principle simplifies the structure of the system, on one hand, and on the other hand providers it with the advantages which other technologies are unable to provide.
The sensor line, which consists of only on twisted-pair cable, simplifies the installation and maintenance and is protected by an end of the line resistor against any tampering with the system.
The VIPER can be installed on almost any type of existing fence.
- The highest detection rate with the best resolution of +/- 10 meters.
- Maximum performance with minimum electronic elements.
- Very low false- alarm rate due to special software algorithm.
- All weather operation.
- User friendly Interface.
- Easy to install and maintain.
- The VIPER can be integrated with any other security system such as IR sensors, CCTV, PTZ cameras, access control systems, VMD solutions, wireless communication systems etc'.
