High Definition Video Switch

The powerful MIL-Spec VH4 video switch processes, manages, and distributes high definition HD-SDI video. With four inputs and three processed video outputs, the VH4 is the ideal network device to efficiently supply video throughout any vehicle. Video distribution, Built In Tests (BIT), and view settings such as Picture-In-Picture, Picture-Over-Picture, and Quad View are easy to remotely manage via CANBus, RS422, and/or USB protocols. The miniature footprint of 5” x 5” x 1.13” and weight of less than 1 pound allow for flexible integration into compact installations. The fully sealed enclosure, wide temperature range, low power consumption and rugged MIL-Spec design permit 24/7 operation in the most demanding environments.
