More than a hundred of Rainbow CCTV's lenses have been installed recently at the US Army's Fort Leonard Wood complex in Missouri USA. The vari-focal lens is designed for applications requiring an extremely wide field of view.
The lens model L163VDC4P has a focal length of 1.6~3.4mm to provide a horizontal field of view of 180°. The DC auto-iris lens has an aperture of F1.4~360 and is compatible with 1/3" and 1/4" cameras.
The units have been installed as part of an extensive CCTV system at Fort Leonard Wood's school facilities. In one education area alone there are 56 cameras each with audio. Formerly every camera was linked to an individual VCR but now a multi-channel system is in operation exploiting digital video recorders (DVRs).
The installer is Electronic Video Systems (EVS) of Springfield, Missouri. EVS's National Sales Manager Tom Eubanks said: "We used Rainbow lenses to replace equipment from another manufacturer which simply wasn't providing the performance that the client wanted. Rainbow were able to accommodate me with the right kind of functionality and the pricing I needed."
With a 1.8-terabyte DVR the user is now enjoying a month's full recording at 15 frames per second. The system is hard-wired and covers a kindergarten to first-grade area, mother-infant facilities and sports courts. The cameras are a mixture of PTZ units and miniature domes.
Electronic Video Systems is a family-owned consultancy and installer currently celebrating its 25th year. The company covers the CCTV, broadcast and audio-visual sectors. It has satellite offices in Oklahoma City and Kansas City.
Fort Leonard Wood was established in 1940 and has now trained over three million men and women. The 3rd Training Brigade instructs 16,000 soldiers annually in combat procedure. The fort is also home to the US Military Police School which provides training to all braches of the military as well as government agencies and US allies in disciplines such as field tactics, human rights, counter-terrorism and counter-drug operations.
Over 100,000 people visit the adjacent Walker Museum of combat and topographic exhibits each year.
