Project Description

Video Walls Case Study

Display walls in Public Sector Command & Control Facilities

Our blue-light, public sector client is responsible for law enforcement in a major UK city. They extensively use public surveillance video as part of their duty to maintain public safety.

Our client carried out a comprehensive programme to modernise its command, control, communication and information systems. Part of this programme involved consolidating more than 30 monitoring facilities into three new centres. In addition, their main command and control room at their headquarters was replaced by installations at the new centres.

The video walls and supporting technology allow the operators and command teams to make more informed and better operational decisions.

The Requirement

With access to over thousands of CCTV feeds, our client needed to simultaneously display numerous video images as well as data and graphical information. A variety of audiences required access to the images including senior police officers, 999 dispatchers, other emergency services and our clients’ own operational support staff. Each group operated from different environments; ranging from cavernous operation rooms and command rooms to large monitoring suites.

As part of the modernisation programme, Cinos were asked to install display solutions in a range of different areas across the three new centres. The new displays had to integrate with existing video matrices and a new command and control system.

Display Walls in command centre

The Solution

For the larger viewing areas, display walls were installed featuring Mitsubishi 50” DLP front access display cubes, known for their excellent image quality and proven reliability. Each Mitsubishi wall was mated with an Extron Quantum Elite Video Wall Image Processor, allowing images and data to be displayed simultaneously in varying sizes and layouts without compromising visual quality.

The largest wall of this type was installed at the North Centre and featured twenty-four displays, arranged in a 12×2 layout. The wall stretches over fourteen metres wide and nearly four metres high which ensured visibility was not an issue in such a large room. In the South Centre, four Mitsubishi walls were installed, including three in the Special Operations Room, thought to be the largest control room in Europe.

During operations, overall responsibility falls upon senior officers located in the Command Suite which consists of four rooms; Gold and Silver command rooms and two additional tactical operation rooms. In these smaller rooms, Cinos installed display walls compromising of Eyevis 46” LCD panels in varying layouts depending on the room size. These displays are less than 20cm deep, making them perfect for smaller spaces.

The technical hub of each Centre is the CCTV Monitoring Suite; a separate area in which a team of support staff have access to incoming video feeds from helicopters, street cameras and mobile cameras. In the South Centre, one hundred 19” LCD screens were installed; split between two display walls; one a 2×40 horseshoe layout and the other a 2×10 straight configuration. In the North Centre, sixty-four 19” displays are installed in a 16×4 layout. These walls were built to suit the size and space available.

The display walls can be controlled locally or centrally from the CCTV Monitoring Suites. Control equipment is located centrally and integrated with an advanced KVM system which allows any display wall to be controlled from any operator position on site. At both sites, the display walls are located some distance away from the central video matrix, with signal extension technology used to transport video and control signals over structured cabling.

The Benefits

Cinos completed the upgrade on time and within budget, delivering improvements in four key areas

Enhanced Capability

  • Simultaneous display of hundreds of CCTV images across sixteen display walls at two sites.
  • Image size and layouts configured for different viewing environments including Operations Rooms, Command Rooms and CCTV Monitoring Suites.

System Integration

The Technology

Avocent Solutions

Avocent AMX analog KVM switching system

The Avocent AMX analog KVM switching system simplifies access, increases your control and delivers optimal real-time video to your desktop. The user station connects to your multiplatform KVM peripherals (PS/2 or USB) and sends the KVM signals over an industry-standard UTP cable to Avocent AMX 5000, AMX 5010, AMX 5020 and AMX 5030 analog matrix switches. This UTP connectivity and analog switching technology provides multiuser access and control to any server in your KVM matrix system.

Mitsubishi XL MegaView Wall

When non-stop monitoring is critical, Mitsubishi’s XL MegaView Wall rear-access models are the preferred choice of system integrators. The entire line is equipped with Mitsubishi’s first Smart Lamp™ and Smart Colourwheel™ features. Each display wall cube stores its own colour characteristics. When a lamp or colourwheel is replaced, this function is then activated, retrieves the datafrom the display wall cube, and performs a re-calibration of the colour adjustments, bringing all of the cubes into perfect colour balance. In addition, the VS-50XLW20U is equipped with an exclusive lamp changer device. The cube is able to sense a complete lamp failure or degeneration in brightness of a percentage that the user chooses and automatically switches to a new lamp.
