Lenkeng HDMI Extender over Ethernet 70m 4K30Hz POC IR Loop LKV223

This HDMI™ Extender includes a transmitter unit and a receiver unit, allows the HDMI™ signal to be transmitted up to 70 meters at 1080p resolution
using a Cat6/6A/7 network cable. It adopts a point-to-point connection configuration, supports bi-directional IR pass-back and 3.5 mm stereo
audio output. It is perfect for outdoor advertising, monitor system, home entertainment, conference, etc.

• HDMI Loop Out: The Transmitter (TX) unit features an HDMI output, allowing you to connect a local monitor alongside the remote one.
• Bi-directional IR Pass-back: Allows you to control your source device (like a Blu-ray player or STB) from the display location, or vice versa.
• Zero Latency: Uses visually lossless compression technology for real-time video playback without the "lag" found in many IP-based extenders.
• EDID Passthrough: Automatically negotiates the best resolution between your source and display.
• Durability: Housed in an aluminum alloy casing with built-in lightning, surge, and ESD protection
