Optex introduces new Echopoint distributed acoustic sensors


Fiber Sensys, part of the Optex group, a leading sensor manufacturer for more than 40 years, has launched Echopoint distributed acoustic sensors (DAS) for advanced intrusion detection across the highest security sites.

The latest evolution in fibre optic sensing technology, the new Echopoint series utilises intelligent detection algorithms to provide point detection of +/- 6m in a range of up to 100km. This highly accurate and reliable detection technology makes the sensors ideal for large perimeters and high security sites, such as airports, logistic centres, railways, critical infrastructure and to protect data conduits and pipelines, where being able to locate and identify the precise point of intrusion is critical.

Thanks to its highly advanced pattern-recognition classification algorithm, the sensors are able to distinguish between common causes of false and nuisance alarms, such as wildlife and environmental conditions, and genuine intrusion attempts. The system also offers immunity to electromagnetic interference (EMI), radio frequency interference (RFI) and lightning providing a reliable and safe solution.

The flexibility and versatility of the Echopoint series is such that they can be operated across multiple applications – installed on fences, buried or in a hybrid layout. When mounted on a fence, the sensors can identify someone cutting the fence or attempting to climb it. When buried, the system can differentiate between footsteps, manual and machine digging and vehicle movements.

To meet the individual needs of every site, the Echopoint series features intelligent software zoning. This means different detection zones can be configured, with the ability to independently adjust the sensitivity and output within each zone, helping to provide maximum capture rates and minimise nuisance alarms.

Masaya Kida, Managing Director of Optex EMEA, says the new Echopoint series has been developed to provide extremely advanced intrusion detection: “By utilising the latest fibre optic sensing technology and highly intelligent classification algorithms, the new Echopoint series is ideally suited to protect large sites where pinpoint intrusion location and detection is required to protect people, assets and infrastructure, and maintain business operations.”

When installed in a loop configuration, the sensors provide cut tolerance, so even if a sensor is cut or disconnected, the system will continue to operate. It can also feature dual redundancy, so that in the unlikely event of a processor failure, the second processor will automatically take over to ensure the wider security system is maintained and remains operational. With an average lifespan of 20 years, Echopoint DAS provides a cost effective and future proof sensing solution.
