Kiloview N3-s is a bi-directional SDI to NDI converter supporting 3G-SDI HD encoding to NDI High Bandwidth with loop-through for real-time monitoring, as well as decoding NDI High Bandwidth back to HD 3G-SDI output.
## 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.
## True HD, Truly Reliable Delivering up to 1080p60 video over NDI High Bandwidth, the N3-s ensures crisp visuals and low-latency transmission. With YCbCr 4:2:2 color sampling, it provides accurate color reproduction and stable image quality for professional HD workflows.
## Flexible Audio Options, Just the Way You Need The N3-s offers comprehensive audio integration to suit a wide range of production scenarios:
• 3G-SDI audio embedding & de-embedding for direct mixer connection
• Real-time analog audio embedding via 3.5mm input
• 16-channel audio encoding & 8-channel decoding
## 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 Versatile Tally Indicators PoE + DC Input USB Keypad Control Audio with Intercom Visual Loss Alerts Compact & Easy Mounting
## 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.
