Baxall a UK manufacturer of CCTV equipment has had its Pyramid matrix system installed in the new IMAX theatre in Nuremberg, Germany. Situated in the heart of Nuremberg, it is built completely underground to a depth of seven storeys and features 18 screens, along with the IMAX theatre itself.
To monitor this number of visitors and cinemas - and all the exits and entrances - an extensive CCTV system has been installed by Videosystems GmbH, featuring 160 cameras and 45 domes. The cameras are controlled by a Baxall Pyramid matrix switching system.
At the heart of the Pyramid system is the matrix itself, featuring 48 video inputs and 16 monitor outputs. A further Baxall 'slave' matrix has been added to it to double the video inputs, along with eight PCB alarm input units. Such a set-up allows any camera in the complex, including the infrared ones in the cinemas, to be held and sequenced on any monitor. In addition to the obvious safety function, this also enables operators and visitors to see what film is being shown and how many seats are still available as the infrared camera images are displayed on monitors outside each cinema screen.
A high speed RS485 link is used to connect the matrices to the cameras, ensuring full and immediate control of the cameras' functions, including fixed and variable speed pan, tilt and zoom. These are operated via four Pyramid keyboards in the control room.
