Leading security distributor, Videcon Ltd, and Graham Firth Communications Ltd, joined forces to design and supply a new, CCTV-based, traffic management system for the M62 motorway.
Graham Firth Communications Ltd is a specialist integrator that designs, installs, maintains and manages temporary CCTV systems for Highways England. The company is involved in many major motorway improvement and maintenance projects across the UK, often with 24/7, remote monitoring. It has an exceptional reputation for prestigious projects of this type.
The M62 surveillance project handles traffic on one of the busiest motorways in the UK between junction 9 and 12, carrying as many as 119,000 cars a day.
Highways England (formerly the Highways Agency) is the government-owned company, which operates, maintains and improves England’s motorways and major A roads. It manages traffic management CCTV systems and on-road signage, as well as providing real-time, web-based information to traffic officers and the public via its Traffic England website. It takes responsibility for all incidents on its road network and is always looking at ways to improve safety. The prime purpose of the new CCTV system was to identify traffic congestion and manage signage and traffic speeds to reduce congestion and improve safety.
Ian Farr, technical director at Videcon, said, “The traffic management system was designed by Videcon and Graham Firth Communications. It comprises 70x Redvision RV30, X-SERIES rugged PTZ dome cameras; a Digifort, open-platform, Video Management System for recording and control, running on high-resilience, DELL servers; Digifort’s free client software running in the monitoring station on DELL PCs controlling 16 monitors set up in multi-screen, alarm screen and report screen modes; and finally a dedicated fibre network infrastructure from specialist manufacturer, Comnet, with massive data carrying capability and low latency for responsive PTZ operation. Videcon was involved in the design, specification and commissioning of the system, calculating bandwidth demands, storage volumes, server capability and client PC requirements.”
RV30, X-SERIES™ rugged PTZ dome cameras, manufactured in the UK by Redvision, were used throughout. They are finished with marine-grade plating and tough, powder-coated paint. They are IP67 weather-proof rated, as well as shock and vandal resistant, making them ideally suited to tough, outdoor surveillance applications like the motorway. The model of cameras chosen includes a wiper to remove dirt, grit salt and rain from its optical, glass, camera window. The cameras are also easy to install, upgrade, replace, repair and service. The Mean Time Before Failure (MTBF) figures for the RV30 are exceptional, at 7 years, minimising on-site failures. Redvision also offers a back to base repair system if any cameras do go wrong.
Ian added, “The Digifort VMS was selected for its intuitive, logical and easy to use front end. It allows the set up and presentation of camera channels to be individually designed for each operator in the monitoring station. It is configured so that motion detection will trigger alarms and put ‘bookmarks’ on the video timeline for quick searching and retrieval of data. This helps identify incidents in real-time, such as traffic braking, slowing and stopping, including when there is an accident.
“Unlike most VMS platforms, Digifort has no annual maintenance fees, so has no ongoing overhead. Analytics can be added for further system intelligence, which includes functionality like tailgating, vehicle counting, presence, enter/exit, appear/disappear, direction filter, speed filter, stationery, loitering, abandoned object and removed object. Further add-on modules include License Plate Recognition (LPR), Briefcam Synopsis, Facial Recognition, Edge Recording and Edge Analytics, meaning there are no limits to system upgrade flexibility.”
The combination of Redvision rugged PTZ cameras; Digifort VMS and analytics software; and ComNet optical networks provides a robust and reliable motorway solution. This combination is now being rolled out across many other motorways across England, designed and supported by Videcon Ltd.
