AFL’s Fiber Security™ provides capable and cost effective perimeter intrusion detection solution for fence lines from ½ mile to 10 miles

Fiber Security™, AFL’s fiber optic perimeter intrusion detection system, enhances a security team's ability to detect and respond to fence line intrusion events while reducing existing system and new construction costs. The system employs a fence-mounted fiber optic sensing cable for vibration detection and a central sensing device analyzes both the magnitude and pattern of the vibration signatures, resulting in a system that is:

• Responsive: Low false positive rate due to noise generated by environmental factors
• Reliable: High reliability for detection of intrusion events (extremely low frequency of false negative)
• Accurate: +/-2.5% accuracy of intrusion event locations over continuous fence line lengths of up to 5 kilometers
• Flexible: Stand-alone system or integrated with pan-tilt cameras and other technologies like infrared systems

An excellent value

AFL’s Fiber Security™ operation and maintenance costs are lower than other security methods which have shorter sensing lengths or require multiple transmitters and receivers. The fiber optic sensing cable is very simple to deploy and affix to the fencing. For a single length of sensing cable, Fiber Security™ assigns individual zones to each camera using software parameters in the sensing unit, while competitors require separately wired and powered zones for each camera. Each zone can be programmed with its own warning and alarm thresholds with a total of 100 zones per sensing system, making AFL’s permiter intrusion detection system the lowest installed cost option available.

Some security requirements are temporary. In these situations the ability to re-use equipment helps lower operating costs of an organization. Fiber Security™ components can easily be moved for temporary needs or completely relocated. Reusable hardware and cabling make this transition easy and cost effective.

Low false positives and negatives

Fiber Security™ automatically adjusts to changing environmental conditions at the fence line to reduce the amount of false positives and negatives. The self-tuning function and tuning performed during installation optimize detection capabilities while reducing the occurrence of false readings. Low rates of false alarms help ensure operator trust in the system and remove the sensory load on operators compared with constant scanning of CCTV monitors. Lowering the amount of alarms and inputs during a threat condition improves decision making during the security team's response.

Robust and flexible system architecture

Fiber Security™ uses standard racking for sensing unit mounts. Cables and components are industry-proven through use by communications providers worldwide. The system also significantly reduces the number of inputs to the master security system when compared to line-of-sight systems. Fiber Security™ offers an additional layer of real-time intrusion detection to enhance existing technologies and communicates with master security systems via dry contact outputs, RS232C or Ethernet.

Sabotage and tamper resistant

Optional armoring of fiber optic cables makes them resistant to cutting. Optical couplers are environmentally protected inside industry-proven splice closures, and the fiber optic sensing unit is password-protected to prevent unauthorized changing of parameters.

Real time intrusion detection

When vibration levels exceed preset thresholds, the fiber optic perimeter intrusion detection system provides a warning which can be used as an initiating signal to direct a PTZ camera towards an event on the fence perimeter, while the sensing unit software evaluates the pattern of vibration against typical intrustion patterns. If the algorithm determines that the signals constitute an actual intrusion, the camera system is already focused on the event area for the security team to review and take action.

Easy maintenance

Fiber Security™ is easy to repair and maintain. Damaged cables can be repaired by arc fusion splicers. Repair loops are designed into the initial fence layout to allow for field repairs with minimal splices.

Parameters can be safely stored on backup media and can be loaded onto a replacement sensing unit in the event of a system failure. The system will return to its fully operational state without the time and expense of reprogramming.

Defeats intruder expectations

Fiber Security™ can be installed on the perimeter in ways that cannot be seen and anticipated by intruders. Properly installed in buried applications, Fiber Security™ detects intruders walking over cable or can detect efforts to breach the perimeter by digging under fencing.
