Electrosonic upgrades control centre with Mitsubishi Electric cubes

Electrosonic has recently installed a new dynamic display system (DDS) at Highways England’s expanded control centre in South Mimms, comprised of 24 67in Mitsubishi Electric LED illuminated ‘cubes’.

“The videowall is a key operational resource allowing for improved tactical and strategic management of congestion and incidents,” commented Garry Packer, technology manager, Highways England.

Electrosonic chose Mitsubishi Electric 67PE78, 67in SXGA+ LED illuminated ‘cubes’ for the DDS system upgrade as they are brighter, of higher resolution and use less power than the previous system, which had been in place for a number of years.

The cubes have 1mm bezels and a 4:3 aspect ratio that match the camera images exactly, making the most efficient use of the display area. The automatic ‘colour balancing’ feature ensures that all cubes in the array give a uniform performance. In addition to the energy efficiency, the cubes are also low maintenance and can operate 24/7.

The DDS is in an 8×3 configuration and can show any combination of video or images across the array, controlled via any one of the 20 operator positions. The majority of images are derived from Highways England’s network of 870 cameras located around the roads in the eastern region. In addition, images from other regions, roadwork cameras, Transport for London and broadcast images can also be selected.

The display receives its inputs from an eyevis Netpix NPX-4800 videowall processor. This was chosen for its flexibility and capability of dealing with many source types. In particular it met Highways England’s requirement that the processor should be able to process directly H264 compressed CCTV images delivered over IP, according to ONVIF (Open Network Video Interface Forum) format.
