DIGITUS HDMI KVM IP Extender Set — 4K/60Hz up to 200 m, Keyboard, Mouse & Touch at the Remote End
KVM over IP4K/60Hz (4096x2160)200 m point-to-pointUp to 253 receivers
The DIGITUS DS-55355 is a 4K HDMI KVM-over-IP extender set: it carries video at up to 4K/60Hz (4096x2160) plus USB keyboard, mouse and touch-screen control between a computer and a remote screen over CAT 6 or better cable — up to 200 m on a direct run, or across your Gigabit network through standard switches. Additional DS-55356 receivers expand it to up to 253 displays.
It is designed for control rooms, interactive kiosks and signage with touch screens, meeting rooms and server rooms: keep the PC in a secure place and operate it at the screen as if it were local. Latency is 120–170 ms at 4K/60 and 80–110 ms in Full HD.
Before you order: Point-to-point reaches 200 m; through a switch each section is up to 120 m. Use Gigabit switches and preferably a dedicated switch or VLAN for the video streams. USB on the extender is USB 2.0 for keyboard, mouse and touch input — not intended for storage or webcams.

Singular Expert Insight · Buyer's Guide
4K/60 with keyboard, mouse and touch over IP is what modern control rooms and interactive signage need. The DS-55355 delivers it with headroom for growth; size the network with proper Gigabit
network switches and the system scales cleanly.
✓ Buy it if you need to operate a 4K computer from a distant screen with keyboard, mouse or touch, or over the LAN.
✕ Skip it if you only need video (DS-55351 is the non-KVM version with IR) or Full HD is enough (DS-55529).
→ Also consider DIGITUS DS-55351 (4K/60 IP, no KVM) or DS-55529 (Full HD KVM IP).
