Intelix INT-HD70-RX HDBaseT HDMI Transmitter

HDMI, IR, RS232, and Ethernet over Single Twisted Pair

Intelix INT-HD70-TX HDMI, bi-directional IR, RS232 and Ethernet  via HDBaseT Transmitter

Intelix INT-HD70-RX HDMI, bi-directional IR, RS232 and Ethernet via HDBaseT Transmitter

The Intelix INT-HD70-TX HDBaseT HDMI Transmitter handles HDMI, bi-directional IR, bi-directional RS232 and Ethernet over a single twisted-pair cable, such as cat-5e or Cat-6.

Leveraging HDBaseT technology for enhanced transmission over shielded and unshielded twisted pair cabling, the INT-HD70-TX features power over HDBaseT (PoH), allowing flexible power on either the transmitter or receiver. Plus, other compatible PoH devices will power or be powered by the INT-HD70-TX.

The INT-HD70-TX supports 1080p, and 3D video up to 70 meters (230 feet). 4K x 2K up to 40 meters (131 feet).  Built-in surge protection and diagnostic LEDs ensure hassle-free and robust installations.  The system is HDMI v1.4 and HDCP 1.4/2.2 compliant, so it handles advanced HDMI video formats, including (but not limited to) 1080p, 4K, 2D, 3D, 120Hz, 240Hz, along with up to PCM 8 channel, Dolby Digital TrueHD, and DTS-HD Master Audio lossless audio formats.

Ideal for use with Intelix INT-HD70-RX HDBaseT receivers (add to cart below).

Wired remote IR emitters and receivers are available as an option, as are a 12-slot rack-mounting kit and a rack-mount power supply for up to 12 devices (add to cart below).

As with virtually all systems that are based upon twisted-pair cable technology, the Intelix INT-HD70-TX HDBaseT HDMI Transmitter will work with virtually any twisted-pair cables, including Cat-5e and Cat-6, but range and bandwidth is directly related to both distance and cable quality, so to get the highest resolutions at the greatest distances, you will want high-quality, low-skew cables.  If you want the very best pre-terminated cables, please consider our VideoTwist cables.

Like most Intelix products, the INT-HD70-TX comes with a two year limited warranty from the manufacturer.
