ADT secures a vital part of medieval England's treasures - the Domesday Book - with a digital recording system that records high resolution images 24 hours a day. One of the requirements of the client's specification was for a system with a high image refresh rate as well as the integration of a number of existing systems
ADT of Sunbury has carried out an installation to protect the Domesday Book, one of medieval England's greatest treasures.

The company was successful in bidding against five other leading companies in the industry for the contract to upgrade the security systems at the Public Records Office at Kew, South West London.

A sealed chamber houses the precious survey document which details who owned what property throughout the country in 1085. It is a key area of this large and complex site.

High specification
ADT installed a new Vicon Kollector digital recording unit. In addition, Vicon 1/3 inch CCD cameras and high speed Surveyor 2000 dome systems are installed to monitor car parks and other public access areas 24 hours a day.

Among the Public Records Office's requirements were the need for higher resolution images over greater distances, improved night vision and high-performance digital image acquisition and storage systems.

The specification also called for the integration of a number of existing systems with the Vicon digital video system, and this was carried out successfully.

Integrating existing systems
The Nova V1344 matrix controls the video switcher, pan-and-tilt, lens and auxiliary functions and can control switching for up to128 cameras and 24 monitors.

Having valuable documents on site meant there was a need for a recording system with a refresh rate of at least 4 frames per second (fps) per camera.

An ADT spokesman said the 8 frames-per-second per camera refresh rate of the Kollector DVR impressed both installer and end-user alike – particularly as the image resolution was high.

Jack Lincoln, Head of Security at the PRO said: "Our purpose in looking for a digital system was so that we could offer the police higher quality images as evidence in the event of an incident.The Kollector DVR is an impressive piece of equipment and is very user-friendly."

The Kollector gave double the fps rate they originally specified and recordings are of good resolution as well as being similar to real-time video recording.

Gilbert Collection under Abloy lock and key

Mid Beds Locksmiths has secured the The Gilbert Collection of decorative arts at Somerset House, London. The company, which is an approved Abloy Centre, was appointed architectural ironmonger and locksmith for the project to protect the treasures valued at over £100m. The museum required a variety of showcases that would show the collection at its best and locking systems that would protect the cases and the building. Mid Beds spokesman, Andy Burr said the biggest challenge was to integrate modern locking systems into a Grade 1 listed building. The diversity of the display cabinets meant that many had to be individually specified. Mid Beds worked closely with Abloy Security, Somerset House Trust and the Gilbert Collection.
