HDMI over Wireless Extender |LPCM 5.1/7.1 Audio Support | Low Latency

This long-range Wireless HDMI Transmitter and Receiver Kit lets you transmit the audio/video signal from an HDMI source to a remote display up to 656 ft. (200 m) away.

Cut the Cord and Installation Costs

This HDMI over wireless extender offers a practical and convenient alternative to traditional video cabling, which eliminates the cost of installing an expensive wiring infrastructure. This bundled kit includes both the transmitter and receiver, helping you avoid the expense of buying multiple devices to accomplish one task.

Ultimate Convenience

This wireless extender kit uses Wi-Fi to transmit a high-definition 1080p HDMI signal, as well as an IR signal for controlling your source device remotely.

With this wireless video extender, you can extend or mirror your device to share documents or multimedia content from anywhere in the room, making it the perfect solution for sharing ideas with your colleagues. It’s also great for digital signage applications because it enables you to install your display wherever you’d like, unlike wired solutions that force you to compromise on location.
