HDMI over CAT5 Extender

The ST121HDBTPW transmits Ultra HD 4K signals up to 330 ft over a single CAT5e or better cable. It serves installers and integrators who need reliable long-distance video distribution without running multiple power lines to the display end.

Power Over Cable Design

Only the transmitter requires the included 12 V DC adapter, while the receiver draws power through the same Ethernet cable. This eliminates the need for a nearby outlet at the display location and reduces cabling to one Cat5e run plus the supplied 1 m patch lead.

4K Resolution Headroom

The extender handles 3840x2160 at 60 Hz and scales down through 2560x1600, 1920x1200 and 1080p without compression artefacts. At the full 100 m distance 4K remains stable; beyond that length or with lower-grade cable the link will drop to lower resolutions or lose sync entirely.

Perguntas sobre este artigo

Will the single power adapter need replacing before the transmitter and receiver units?

The extender ships with one 12 V DC, 1.5 A power adapter that powers both units through the CAT5 cable, so only that adapter may need replacement over time.

At the full 100 m cable run, which resolution drops out first?

3840x2160 at 4K is supported up to the full 100 m distance, so no listed resolution is lost before the cable-length limit is reached.

Does the transmitter or receiver generate noticeable heat when running continuously?

Each unit draws only 0.5 A at 100–240 V AC input, indicating low power draw and minimal heat during all-day operation.
