HDMI extenders in this range carry HDMI video signal beyond the cable lengths a standard lead supports, typically over Cat5e/Cat6 or coax runs. They suit CCTV control rooms, offices and retail back-of-house sites where a monitor or display sits far from the DVR, NVR or PC source.

How to choose

• Run length needed — match the extender's supported distance to the actual cable run, including any slack for containment.
• Cable type available — check whether the unit runs over network cable, coax, or another medium already installed on site.
• Number of displays — confirm whether you need a single-output extender or one that supports multiple screens.
• Resolution requirements — match the extender's supported resolution to the connected display and source device.
• Power arrangement — check whether the transmitter and receiver units need local power at both ends.

Choosing correctly avoids picture dropouts or having to re-run cable later. Buyers installing new control rooms or retrofitting monitors into existing racks should check compatibility with the source device and display before ordering.
