Profile: Videoswitch specializes in providing digital recorders, domes, video processors, keyboards, interface, service parts and software. We supply a range of fixed mini-domes for internal and external use. Its feature include vandal resistance, built-in IR and micro size. The Vi-A12 distribution amplifier has numerous applications where individual video sources need feeding to multiple devices such as monitors, digital recorders and transmission equipment. This unit provides the flexibility to be configured for twelve-way distribution, for dual six-way distribution or quad three-way distribution. Input termination is also selectable by DIP switch and units may be cascaded to provide distribution of video to larger numbers of devices (12, 24, 36, 48 etc). This version has the added functionality of video loss monitoring. Status LEDs on the front panel indicate the presence of video on each of the four inputs. An alarm LED and alarm relay operate if video is lost on any of the inputs or if any of the amplifiers or power regulators fail. This is a key feature in larger systems or safety-critical applications such as road, rail and air transport systems.
