The YAEL-15 line of taut wire perimeter intrusion detection systems combines the deterrent properties of an actual physical barrier (fence) with a highly advanced intrusion detection system.

Whenever displacing, lifting, climbing or cutting any of YAEL-15’s fence wires makes an intrusion attempt, the system will generate an alarm which will be displaced in the control room.

The YAEL-15 system uses a single, self-balancing analog sensor to monitor all the fence wires installed at a section. The sensor is linked to all the fence wires through a stainless steel collector wire, installed on a sensor post, to which all the fence wires are mechanically clamped. A displacement of any of the wires during an intrusion attempt causes a change in the tension of the collector wire, which is translated by the sensor into an analog signal proportional to the displacement. A microprocessor-based controller to initiate alarms at the control room analyzes the signal. Despite the very high degree of sensitivity and probability of detection, the YAEL-15 system has a very low false alarm rate (FAR) of less than one alarm per three months per one km, and remains unaffected by winds, rain, hail, snow, shifting of the soil, etc.

In addition, the system is not triggered by forces of less than 7 kg (15 lbs.), avoiding nuisance alarms caused by small animals, such as rabbits, birds, cats or dogs.

The YAEL-15 self-balancing feature that allows it to operate even after severe damage to the fence occurs assures continuous comprehensive surveillance of the entire system. This important capability prevents any system downtime and avoids the need for middle-of-the-night maintenance, even if wires are cut during an intrusion attempt.
Whenever displacing, lifting, climbing or cutting any of the detecting wires makes an intrusion attempt, the detectors immediately inform the system's central control unit.

The YAEL-15 system can be installed at the customer's premises by the manufacturer on a comprehensive turnkey basis as a stand-alone, wall-mounted or as an addition to an existing structure. YAEL-15 can, as well, be supplied to the customer in ready assemblies for self-mounting on the existing or specially designated fence posts.
In the stand-alone configuration the YAEL-15 system can be mounted on a variety of fence posts, including the standard angle iron, pipe or concrete post of any size. When wall-mounted or as an addition to an existing structure, YAEL-15 can be installed as short posts, with or without outriggers.

A YAEL-15 system fence can follow the contour of nearly any terrain, and can be any desired height and length.
