Marmitek TV Anywhere Wireless 4K HDMI Extender – 50 m Through-Walls, IR Return & USB

The Marmitek TV Anywhere Wireless 4K is a wireless HDMI extender that transmits 4K video from any HDMI source — such as a satellite decoder, Blu-ray player, or Media Center PC — to a second TV or projector in another room, up to 50 m through floors and walls, or up to 200 m line of sight. No cabling between rooms is required.

In addition to video, the system provides an infrared return channel so you can operate the source device with a remote from the receiving room, and a USB extension function so a mouse and keyboard connected to the receiver can control a PC connected to the transmitter. A loopthrough output on the transmitter allows both locations to watch the same content simultaneously.

• Infrared return function (30–60 kHz) for remote-controlling HDMI source devices from the receiving room
• Built-in USB extension: connect keyboard and mouse to the receiver to control a PC at the transmitter
