Reservoir protection

by Mark Rowe

The need to protect the integrity of the fresh water supply led the UK water and waste company Thames Water to add to the security along one side of the perimeter of reservoirs in south London, where a public footpath has provided easier access for trespassers and committed graffiti ‘vandals’ to enter.

The Zaun Group had already installed ArmaWeave and razor topping around the site, pictured; so Thames asked software security firm EyeLynx to design a solution based on its SharpView CCTV system to protect the CNI (Critical National Infrastructure) site.

Zaun Group companies EyeLynx and Binns installed two temporary CCTV masts with PTZ cameras, thermal cameras with video analytics, horn speakers and WiFi to link the two with a SharpView network video recorder.

CPNI-approved PIDs (passive infra-red detectors) were also fitted which, integrated with SharpView, provide the site with a triple layer of electronic security. The system can provide alarms and CCTV video so whenever a camera or vibration sensor detects a potential breach of the fence line, the horn speakers can broadcast audio warnings, send alarms to security personnel and capture video evidence.

The Zaun Group incorporates Binns Fencing, EyeLynx, Zaun and Zaun Middle East.
