Digitus HDMI over IP PoE Extender Set, 4K/60Hz, up to 200 m point-to-point, One-to-Many via Switch, IR, Black

The Digitus DS-55353 is an HDMI over IP extender set (transmitter + receiver) that sends 4K/60Hz HDMI over Cat6 — directly up to 200 m, or through a Gigabit network switch to as many as 253 receivers — for signage, classrooms, bars and control rooms that need one source on several screens.

Both units are powered by PoE, so a PoE switch feeds video and power over the same cable. You start with one screen and add receivers later on the same network, each up to 120 m from the switch. IR control travels along, so the source can be operated from a display location.

• 1 × transmitter (TX)
• 1 × receiver (RX)
• 2 × IR cable, 1.0 m
• Operating instructions
• Not included: power adapters (optional DC 5V/1A), network cables, HDMI cables, network switch

• One source can feed many screens: add receivers to the same switch, up to 253 in total.
• With a PoE switch there is no power socket needed behind any screen.
• Direct point-to-point reaches 200 m; through a switch each segment can be up to 120 m.
• Video is H.265 compressed: latency is about 150–220 ms at 4K/60Hz and 80–130 ms at Full HD — fine for signage and presentations, not for gaming or live mixing with audio delay sensitivity.
• The housings are wall-mountable metal units that can sit behind a display.

• It will not power itself without PoE or the optional 5V/1A adapters (not in the box).
• It does not extend keyboard and mouse (no KVM).
• It is not suited to a busy office LAN without planning — multicast video needs a capable Gigabit switch, ideally a separate VLAN.
• It is not a zero-latency extender — fast gaming or lip-sync-critical live use is not its purpose.
• Powerline adapters or Wi-Fi bridges in the path are not a suitable network for it.
