A market-leading CCTV system, based on behaviour-recognition software and state-of-the-art intelligent cameras, has been installed by Portsmouth City Council, to increase the effectiveness of the camera monitoring.
Perceptrak™, supplied by Smart CCTV Ltd of Havant, has been set up to watch quiet areas such as car parks, stairwells or corridors in buildings and streets at nighttime. Perceptrak™ uses the latest software to analyse images using up to 18 pre-defined criteria such as ‘converging people’, ‘fast car’ and so on. When it sees something untoward happening, the system sends an alert to the control room. This allows the security officer to make a human decision on whether to monitor the scene and make an appropriate response. It also ensures that many more scenes are being watched than is normally possible, hence helping to make Portsmouth city a safer and more trouble-free zone.
Ray Stead, CCTV manager at Portsmouth City Council, who decided to install Perceptrak™ for the City, said: “Following a successful trial period in 2006, we decided to install the system on a more permanent basis to prove proof of concept after improvements had been made to the software and because of the quantifiable benefits to the control room outcomes.”
Nick Hewitson, managing director of Smart CCTV, added: "We believe that this is the first fully installed example of video analytics being used in a city centre control room in the UK. As a local company we are very pleased to be working with Portsmouth City by providing leading edge technology to make their CCTV control room one of the most effective in the UK."
In the area covered by the Portsmouth City Council control rooms, there are 142 cameras with live monitoring, and the CCTV operators watch over 24 monitors simultaneously. Perceptrak™ is run in the background looking at some of those cameras that are not displayed to the operators until an alarm sounds.
