The Kiloview U40 (often cataloged under part number KIL-U40) is an ultra-compact, professional 4K HDMI-to-NDI hardware video encoder. Shaped like a puck and measuring just ninety millimeters in diameter, its primary purpose is to convert a real 4K video signal at sixty frames per second from an HDMI camera source into an IP-based Full NDI stream. This enables you to transform any standard mirrorless camera, camcorder, or PTZ camera into a high-end Network Device Interface (NDI) production camera using a single ethernet drop.
Core Engineering and Structural Features
-
Dual-Protocol NDI Gateway: The hardware natively converts standard HDMI 2.0 or compatible USB inputs directly into high-bandwidth Full NDI (running around two hundred and fifty megabits per second for a 4K sixty stream). Additionally, it functions as an IP protocol bridge, converting network streams like SRT, RTMP, RTSP, and HLS into high-efficiency NDI HX streams.
-
Super PoE with Power Passthrough (DC Out): When powered via Power over Ethernet Plus, the device routes surplus electrical current outward. It features a twelve-volt DC output jack that can deliver up to fifteen Watts of continuous power to operate your camera body, an on-camera field monitor, or an external recorder alongside the encoder.
-
Integrated Live Production Tally: The physical disk housing features bright, distinct built-in tally lights that illuminate automatically based on network metadata. They flash red when your camera feed is pushed live to the Program (PGM) mix and green when selected on the Preview (PVW) bus.
-
PTZ Camera Control Translation: It supports hardware PTZ control over IP or via USB-to-serial expansion adapters (supporting RS-232, RS-422, and RS-485 standards). This passes camera movement commands like Sony Visca and Pelco-D straight through your network without requiring dedicated control wiring runs.
-
Advanced Passive and Active Cooling: Because processing 4K NDI produces significant thermal load, the round shell is forged from high-grade aluminum alloy. It features ventilation slots along the top rim, a multi-slot geometric interior heatsink, and an ultra-quiet thirty-five millimeter fan operating at a near-silent eighteen point three decibels.

💡 Operational System Tips for the KIL-U40
The Network Segmentation Isolation Practice: The inclusion of dual gigabit ethernet interfaces allows you to configure advanced dual-network workflows. For complex remote broadcasts, connect one network port to a Wide Area Network (WAN) to ingest a remote SRT or RTMP field stream, and bridge that stream through the internal processor to output a clean NDI HX feed into your local production Local Area Network (LAN) via the second port. This completely isolates your high-volume local NDI broadcast environment from erratic external web traffic.
-
Managing Full NDI Bandwidth Limits: If you configuration involves packing multiple U40 encoders onto a single stage layer, calculate your infrastructure limits before going live. A single U40 streaming full 4K video at sixty frames per second requires a sustained pipeline of roughly two hundred and fifty megabits per second. Running four of these units simultaneously will maximize the data limits of a standard gigabit network switch. If your bandwidth headroom drops too low, access the Web management interface and adjust the encoder output down to 1080p sixty frames per second (reducing the footprint to one hundred and twenty-five megabits per second) or switch to NDI HX.
