Compare support for the HDMI source formats used in your system, including resolution up to 4K, refresh rates up to 60 Hz, HDR, HDCP, and video formats such as 4:4:4 when specified. Also check for embedded audio and control pass-through, such as RS-232 or IR, if the encoder needs to carry sound or support remote device control over the network.

Use a Gigabit Ethernet network with enough capacity for the aggregate video, audio, and control traffic, including headroom for simultaneous streams and other network activity. Confirm that switches support the encoders’ UDP traffic, then consider VLAN segmentation, Quality of Service settings, low-latency paths, and redundant links for larger installations.

Single-channel HDMI UDP encoders process one HDMI source, while dual-channel units process two independent HDMI sources in one enclosure, which can help conserve rack space and simplify centralized installations. Rack-mounted models suit equipment rooms and centralized racks, while wallplate models place the encoder near the source in flexible or reconfigurable spaces, reducing the need to run HDMI back to a rack.

Plan the system around the number of HDMI sources, display endpoints, network capacity, and installation locations, then select single- or dual-channel encoders that support low-latency video, embedded audio, and RS-232 or IR control pass-through over Gigabit Ethernet. For security and future expansion, consider encoders with encryption and network redundancy, use managed network infrastructure with room for additional endpoints, and choose rack-mount or wallplate form factors to suit centralized or distributed installations.
