Kiloview N40 Plus 4K HDMI/NDI Bi-Directional Video Converter

Kiloview N40 Plus is a compact HDMI-to-NDI bi-directional converter purpose-built for handling NDI High Bandwidth video workflows. It supports up to 4Kp60 resolution with HDMI input, output, and loop-through, while remaining fully compatible with lower-resolution sources.

Featuring Tally indicators, a high-visibility LCD screen, intercom support, PoE power supply, and PTZ camera control, it is the ideal tool for professionals seeking high-quality, high-bandwidth NDI transmission with no compromises.

Bi-directional HDMI ↔ NDI High Bandwidth Converter
The N40/N40 Plus is purpose-built for high-quality, low-latency NDI High Bandwidth workflows over HDMI.

• In encoding mode, it converts HDMI signals up to 4Kp60 into NDI High Bandwidth streams for seamless IP-based distribution.
• In decoding mode, it receives NDI High Bandwidth streams from the network and outputs them via HDMI, with support for HDMI loop-through to simplify signal routing.

Real 4K, Really Professional
Delivering up to 4Kp60 (UHD) video encoding and decoding, the N40/N40 Plus ensures exceptional visual clarity. With YCbCr 4:2:2 color sampling, it guarantees accurate colour reproduction and consistent, high-fidelity image quality.

Flexible Audio Options, Just the Way You Need
The N40/N40 Plus offers comprehensive audio integration to suit a wide range of production scenarios:

• HDMI audio embedding & de-embedding for direct mixer connection
• Real-time analog audio embedding via 3.5mm input
• 2-channel synced audio, with support for mapping from up to 16 audio input channels

Versatile Tally Indicators and LCD Screen
The N40 features bright, front-facing tally indicator for PVW/PGM, along with an additional rear tally light to support team coordination during production. Exclusive to the N40 Plus, the 1.14” LCD screen complements the rear tally indicator by adding real-time status monitoring, mode switching, and an additional front-facing tally display—streamlining on-site operation and team communication.

Seamless NDI Switching, Zero Disruptions
In decoding mode, you can preconfigure up to 9 NDI sources and switch between them directly via the web interface. Switching is instant and stable with no blackouts, stutter, or signal loss. It also allows you to fine-tune the transition timing to match the pace of your live production.

PTZ Control for All-in-One Production
The N40 Plus enables flexible PTZ camera control without needing additional controllers. It supports serial connections (RS-232/RS-485/RS-422) via USB and mainstream network protocols. This allows precise pan, tilt, and zoom adjustments, enhancing multi-camera live streaming and conference setups with seamless integration and user-friendly operation.

Power Flexibility with PoE and DC Input
The N40 Plus supports PoE, allowing power and data transmission over a single Ethernet cable. It also offers flexible power options, including USB PD fast charging, wide-range DC input (5V–18V), and support for camera batteries or other compatible sources.

Control with a USB Keypad
In decoding mode, you can preset up to 10 NDI sources (0–9) and quickly switch outputs using a connected USB keypad. You can even use the keypad to control a PTZ camera, making it the most affordable PTZ controller available.

Audio Support with Real-Time Intercom
With USB headset support and integration with the Kiloview KIS Intercom System, the N40 Plus enables real-time voice communication for smooth team coordination during production.

Visual Input Loss Alerts for Instant Issue Identification
When a video source or network stream is interrupted, the system automatically displays a preset “No Video” screen or a custom PNG image (1920 × 1080 or 1280 × 720), instead of defaulting to a black or blue screen. This maintains a clean, professional output while helping users quickly pinpoint input-side issues—minimizing downtime and avoiding confusion.

Compact Design with Easy Camera Mounting
The N40 Plus features a compact design and comes with a standard threaded cold shoe mount, making it easy to attach directly to a camera.
