With a ZeeVee ZyPer4K Infrared (IR) transmitter and receiver, you can control your televisions, media sources, and other components with up to 4K resolution via your remote control from up to 40km (about 25 miles) away. Change channels, adjust volumes, or control your media from practically anywhere using the ZyPer4K video distribution system. The ZyPer4K dual band receiver can receive infrared (IR) signal signals from 34-60KHz and send the information to the ZyPer4K encoder or decoder, where, using a standard 10gb network switch, can transmit the data over the network back to the source. This system will enable you to control most major A/V components using the existing IR controller, such as an amplifier, cable box, stereo receiver, satellite TV receiver, CD player, DVD player, Blu-Ray player, or other components over very long distances with virtually instant response time. This is especially valuable in commercial environments where you can secure your AV components in a central and secure location, but still control them using simple remotes where needed. With the ZeeVee ZyPer4K Infrared emitters and receivers , they require the use of the ZyPer4K encoders and decoders and use a small plug to connect into each encoder or decoder unit.
