Bi-directional 3G-SDI ↔ NDI High Bandwidth Converter

The N3-s is purpose-built for high-quality, low-latency NDI High Bandwidth workflows over 3G-SDI.
● In encoding mode, it converts 3-SDI signals up to 1080p60 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 3G-SDI, with support for SDI loop-through to simplify signal routing.

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.

More Features

PTZ Control for All-in-One Production

The N3-s 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.

Versatile Tally Indicators

The N3-s features bright, front-facing tally indicator for PVW/PGM, along with an additional rear tally light to support team coordination during production, providing clear signal status cues for smoother camera operation and switching.

Power Flexibility with PoE and DC Input

The N3-s 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 N3-s 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 N3 s features a compact design and comes with a standard threaded cold shoe mount, making it easy to attach directly to a camera.
