Finding a safe harbour

August 2019 CCTV, Surveillance & Remote Monitoring

A video surveillance system with around 40 IP and thermal cameras from Dahua Technology has been installed at Yarmouth Harbour on the Isle of Wight. The harbour consists of a large marina, docks for the Wightlink ferry terminal, and pontoons and boat moorings upstream.

The previous surveillance system was becoming outdated, with poor picture quality and cabling issues. Following a number of thefts from boats and boat fires in neighbouring harbours, a new solution – including thermal imaging capability – was specified.

Dahua solution

The Dahua cameras are a mix of thermal bullets, IR bullets, Ultra PTZs, IR domes and fisheye cameras. The thermal cameras are especially suited to wide-area outdoor video surveillance and are ideal for the large, water-based environments at the harbour. The cameras feature Vox uncooled thermal sensor technology and high thermal sensitivity at less than 40 mK, enabling them to capture more image details and temperature fluctuations. With built-in fire detection functionality, the cameras provide an extremely sensitive fire alarm system.

The IR bullet cameras feature highly efficient H.265 encoding technology, PoE and IR illumination at up to 50 metres, as well as a wide dynamic range, providing vivid images even in the most intense contrast lighting conditions and delivering powerful day/night surveillance in a compact package.

At one of the moorings upriver, there is no power supply on isolated pontoons, so wind power and solar energy have been harnessed to operate the cameras.

Images are transmitted wirelessly back to a control room at the main harbour office. When the control room is not staffed, Yarmouth Harbour can nominate individuals to receive alerts and images on their tablets and smartphones via the Dahua surveillance app.

As well as the harbour itself, the system also covers the adjacent Yarmouth pier, a Grade II-listed structure said to be the longest wooden pier in the UK and recently refurbished. Automatic people-counting technology has been incorporated into the cameras at the pier’s entrance to monitor numbers on the pier as a health and safety measure.

Benefit obtained

“The new surveillance system has transformed our ability to monitor the harbour for the safety and security of our customers, staff and the visiting public,” said Dave Rice of Yarmouth Harbour Commissioners. “The HD picture quality is superb and you can pick out people’s faces, so there is no comparison with the previous cameras. The system has proved straightforward to use and we are delighted with its performance to date.”

“This proved an interesting project to work on, not least because parts of the installation had to be carried out by boat,” said Chris Snell, managing director of security installation firm, Central Southern Security. “The Dahua equipment has been a pleasure to work with and will provide Yarmouth Harbour with a great solution for many years to come.”
