Electrosonic Upgrades Highways England's Eastern Regional Control Centre

02 June 2016

Electrosonic, an international audio-visual systems integrator has recently installed a dynamic display system (DDS) at Highways England’s Eastern Regional Control Centre in South Mimms.

Comprising of 24, 67-inch LED illuminated ‘cubes’, the new DDS technology has delivered a solution that is virtually maintenance free, energy efficient and suitable for 24/7 usage.

Highways England have expanded the capability of its South Mimms Control Centre, making it one of their largest.

As their existing dynamic display system had been in place for a number of years, a replacement using enhanced technology was required.

“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 determined that Mitsubishi Electric 67PE78, 67-inch SXGA+ LED illuminated ‘cubes’, were the best solution for Highways England, owing to several key factors. They are brighter, of higher resolution and use less power than their predecessor.

Additionally, they do not require any consumables such as projector lamps that would need regular replacement. The cubes have a 4:3 aspect ratio that match the all-important camera images exactly, making the most efficient use of the display area.

Their automatic colour balancing feature ensures that all cubes in the array give a uniform performance. They are highly energy efficient, low maintenance and can reliably support 24/7 usage.

The cubes also benefit from an extremely narrow 1-mm bezel, which presents a virtually seamless image when magnified across a 2x2 cube array. The DDS, which dominates the control room and consists of an 8x3 array of cubes, can show any combination of video or images across the array, determined by any one of the 20 operator positions.

The vast majority of images are derived from Highways England’s network of 870 cameras located around the regions roads. 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.

Electrosonic maintains an on-going service relationship with various Highways England sites, having now successfully completed a total of eight projects for them.
