Seven responded to a European tender to provide an integrated perimeter detection system for a remote national critical infrastructure site. The speculation was for a solution capable of providing intruder alarms linked to a local monitoring facility.
The site in question was a few hundred acres and located in a remote area. The main facility was a brick built single storey building with a number of adjoining work areas and limited security fencing. Whilst the security solution was to deliver local monitoring at the site it also needed to offer 360 degree coverage. Discreet technology was essential so that the site did not detract from the local environment by appearing to be ‘fortified’.
Due to the geography of the local area combined with the layout of the site and buildings, a bespoke system was put in place to completely secure the premises. The permanent system components included:
To supplement the permanent installation, 4 portable CCTV sensors were provided for quick installation at different locations throughout the site on an ad-hoc basis. Each portable CCTV sensor is self-supporting with a 30Ah battery, WiMAX transceiver, 980x zoom CCTV camera and pan and tilt unit fitted to a lightweight tripod.
Additionally, 12 ground sensors comprising of either a PIR detector or pressure pad connected to a small battery-powered transmitter supported the portable deployment components. When triggered, the ground sensors communicate an alarm to a central node located at the monitor room via an antenna mounted on the mast.
When all system components were deployed, the central monitor room was capable of monitoring and controlling all 5 cameras independently. The radar was able to rotate the mast-mounted camera to any area where activity was detected. An integrated software application displayed the radar software and the location of any deployed ground sensors in addition to the 5 video feeds.
After the civil works were completed (fence and mast) the surveillance system was installed on two site visits. The system has now been in successful operation for over 4 years with little maintenance required.
