PIDS Sensor Fence | Perimeter Security Fence

Securenics’ Perimeter Security Fence system -- the Electric Charge Sensor Fence - incorporates the latest, most advanced technology into a complete perimeter intrusion detection solution. It is the first sensor fence in the world that uses a special algorithm of electric charge displacement which is based on friction and electromotive force change of fence sensor cables to detect intrusions.

Securenics’ PIDS Sensor Fence has a near 100% probability of detection and causes almost no false alarms. It requires no additional electric infrastructure and provides the longest warranty in the world. PIDSFence offers the most complete and reliable perimeter security fence solution at a competitive price.

The importance of automatic security systems for public facilities, military bases and even VIP residences has long been recognized. PIDS Sensor Fence is ideal for any facility that strives to improve perimeter security by providing round the clock monitoring for the protection of lives and property. 

Securenics’ Perimeter Security Fence system works by sensing any change in electric charge on the sensor fence caused by an intruder through friction. It causes almost no false alarms and detects intrusions with a probability of near 100%. In addition to detections, it also senses electric pulse signals from intruders when they use electric tools such as welding machines or generators within a short distance from the sensor fence.

PIDS Sensor Fence detects climbing a fence and a corner of the sensor fence as well as climbing up ladders and underground digging. Unlike other sensor fences, it requires few installers and does not require additional electric infrastructure like anti-lightning or grounding. It can be deployed onto any barrier such as a vinyl fence, a chain link fence or even a concrete wall.

PIDSFence Components:

The PIDSFence works on friction electromotive forces received from the passive sensor cable and the cable connection points (points where the passive sensor cable is fastened to the fence). These signals are detected by the PIDSFence controller.

Sensor

  • Passive Electric Charge Sensor Cable (PECSC)
    The PECSC is mounted on the fence and generates an electrical signal in response to unauthorized activity on the fence. 

    The sensor length depends on the length of the guarded zone, the fence height, the number of supports, and the layout of the PECSC on the fence.

  • Coaxial Cable (CC)
    Shielded coaxial cable connects the cable adapter and the ASU-35p. Maximum length is 5 km.
  • Cable Adapter (CA) and Branch Sleeve (BS)
    The coaxial cable connects the PECSC and the coaxial cable. For gates and wickets, use an extended adapter to permit a spiral wrap hose for the coaxial cable protection. 

    The branch sleeve is used when connecting two separate portions of the PECSC and for shielding and sealing connection points.

    The cable adapter and branch sleeve are equipped with cable ties for fastening to the fence.

  • Terminal Device (TD)
    The terminal device provides continuous monitoring of the PECSC and the ASU-035p with coaxial cable integrity. It is also the shielded and sealed endpoint of the PECSC.

 

Controller

  • Analog Sensing Unit (ASU-35p) for fenceASU is used for detecting the sensor signal and generating the alarm signal.The ASU is in a metal case. Located inside the case is an electronic board which contains the circuit elements of the ASU, the input module, the terminals for the external circuit connection, and the PIDSFence controls.

    The ASU case also has installation fasteners.

  • Programmable Logic Controller (PLC)The PLC performs sensor data acquisition and data communication to the main server by TCP/IP.The PLC connects the ASU-35p and the user’s security server through an Ethernet switch.

PIDS Sensor Fence Features:

  • The ASU-35p is powered by an uninterrupted DC power source with supply voltages from 8-35 V.
  • If voltage drops below 5 V, the ASU-35p goes into Alarm mode.
  • Minimum length of the passive electric charge sensor cable is 1.2 m.
  • Maximum length of the passive electric charge sensor cable is 500 m.
  • Maximum length of the detection zone depends on fence type and the sensor cable layout. If the sensor cable length is 500 m, detection zone is 166-500 m.

Available Fence Types

To ensure proper detection, high noise immunity (no false alarms and lowest-possible nuisance alarms) and sabotage resistance, the following guidelines should be followed:

  • Prisons / Correctional Facilities
  • Ensure proper fence mounting: flexible fences should be stretched uniformly with fence-specific tension force.
  • Combine different types of layout and fastening methods.
  • Ensure fence uniformity: the fence should be made of a uniform material because different-material sections, when subjected to an unauthorized action, will generate signals of different strength.
  • Proper tightness of PECSC upon installation.
  • Set the ASU sensitivity setting to the specified detectability
