Hall KVM‑HDU‑4 4‑Port HDMI KVM Switch With USB 2.0 Hub, 4K Video Support, No PSU, Black

Optimize control rooms and monitoring stations with the Hall Technologies KVM‑HDU‑4 4‑Port HDMI KVM Switch. Designed for security, surveillance and IT environments, this compact KVM switch lets technicians and operators seamlessly manage four computers or NVRs from a single keyboard, mouse and display—reducing clutter and improving response times.

The unit supports ultra‑high resolution video (up to 3840x2160 at 60 Hz) so video evidence and live camera streams remain crisp and accurate. An integrated 2‑port USB 2.0 hub routes peripherals such as webcams, touchscreens or USB scanners to the active host, while keyboard/mouse and HDMI emulation ensure each connected PC continuously detects input devices and a display. Smart EDID management and front‑panel or hotkey switching deliver predictable, interruption‑free transitions between sources. The metal housing and low 0.7W idle consumption suit demanding 24/7 installations, and the KVM can run from host USB power with a 5V DC input available for power‑hungry setups.

Ideal for security operators, broadcast and IT admins, the KVM‑HDU‑4 consolidates control without compromising resolution. Add it to your surveillance or monitoring workflow to simplify operations and speed troubleshooting.
