Kiloview U40 4K NDI Encoder
Ultra-compact 4K HDMI to Full NDI encoder powered by PoE. Brings 4K Full NDI to space-constrained camera positions via a single Ethernet cable.
- Ultra-compact form factor — one of the smallest 4K NDI encoders available, for positions where space is the primary constraint
- HDMI 2.0 input at 4K — accepts 4K cameras at up to 4K30, or 1080p60 for full HD 60fps video
- Full NDI and NDI HX output — 4K NDI to any NDI production software or NDI HX for bandwidth efficiency
- PoE powered from the Ethernet connection — single network cable provides Gigabit connectivity and power, no separate PSU needed
- Auto-discovery via mDNS — appears immediately in vMix, OBS, Wirecast and NDI software without manual configuration
- Compact step up from the E2-NDI — same PoE simplicity with 4K capability added
What is the Kiloview U40?
The U40 is an ultra-compact 4K NDI encoder — HDMI 2.0 to Full NDI over PoE-powered Gigabit Ethernet. The compact 4K equivalent of the E2-NDI, adding 4K capability in a similarly small PoE-powered form factor. The correct choice when 4K NDI is needed at a camera position where physical space is limited and single-cable PoE simplicity is preferred.
4K NDI network bandwidth
Full NDI at 4K requires approximately 300-500 Mbps per stream. A Gigabit Ethernet connection handles one 4K Full NDI stream adequately. Multiple simultaneous 4K Full NDI streams require 10GbE infrastructure. Consider network bandwidth requirements carefully for multi-4K NDI deployments.

Maximum resolution?
4K30 (3840x2160 at 30fps) or 1080p60 via HDMI 2.0. For 4K60 NDI see the Kiloview S2 or E3.
U40 vs E2-NDI?
The U40 adds 4K HDMI 2.0 capability. The E2-NDI is 1080p maximum. Both are compact and PoE powered.
The U40 outputs Full NDI and NDI HX to any NDI production software on the same Gigabit network.
