Wireless HDMI Extender Kit, Transmitter/Receiver, IR Control, Dual Antennas, Up to 165 ft. (50 m)


All-in-One HDMI Wireless Extender for Displaying Video in Boardrooms and Conference Rooms
This complete wireless HDMI transmitter and receiver system is recommended for video presentations in conference rooms, trade shows, home theaters, digital signage and other applications in which connecting long video cables could be a burden. The B126-1A1-WHD3 extends 1080p video and stereo audio signals from an HDMI source device to an HDMI display up to 165-ft. (50.29 m) away. No bulky or costly cabling infrastructure is needed.
Plug-and-Play Operation for Quick Setup and Immediate Use
The wireless HDMI audio/video transmitter and receiver set works right out of the box with no software or drivers required. Mounting hardware is included for installing the units on walls or other flat surfaces. Connect the receiver to the display and the transmitter to the source with user-supplied HDMI cables (such as Tripp Lite's P568-Series). Then, connect the included IR cables for remote control, and plug the dual power supplies into an AC outlet.
Wireless Transmission Saves You Money on Cable and Installation Costs
The B126-1A1-WHD3 eliminates more than just hassles. You'll save on the costs of cabling infrastructure and the labor to install it. Cable clutter is reduced, and you will enjoy more flexibility in placement of the source and display with no cables to relocate when you want to reconfigure the room. The transmitter and receiver units communicate over a 5 GHz wireless frequency that allows fast data transmission and reduced interference from other wireless sources. Be sure the transmitter and receiver share a direct line of sight for best results.
IR Pass-Through Technology Lets You Control the Video from an Extended Distance
The IR cables let you control your source device with its remote (play, pause, fast forward, etc.), while you're standing near the receiver located up to 50 meters away. Make sure the transmitter's IR bulb is within sight of the source and the receiver's IR bulb is in range of the source's remote.
Transmits Crystal-Clear 1080p Video for High-Definition Presentations
The B126-1A1-WHD3 ensures high-definition performance in a one-to-one application, where there is less obstruction to occur. It supports video resolutions up to 1920 x 1080 (1080p) at 60 Hz with 24-bit Deep Color (8 bits per channel) and stereo audio. AES 128 encryption protects your wireless transmissions. LEDs indicate when the transmitter and receiver units are receiving power, transmitting data and connected to a wireless signal.
