Broadcast-Grade Interlaced and Progressive Signal Handling

The N50 fully supports 1080i60 interlaced signals throughout the entire processing chain:
• 1080i50/i60 in → 1080i50/i60 out
• 1080i50/i60 in → 1080p50/p60 out
This flexibility ensures smooth operation in studios working with both interlaced and progressive formats.

It also supports SEI timecode insertion for NDI HX and NetStream, enabling synchronization of multi-camera feeds using either system time or source device time.

*The N50 processes 1080i50/i60 signals and provides native 1080i50/i60 output. This feature is available when the device utilizes ​ NDI HB or H.265 codec, but is ​not supported under the H.264 codec.

• Tally Indicators: Front panel LCD, rear Tally LEDs, and external Tally support provide clear red/green indicators for PGM (program) and PVW (preview) status.

More Features

Redundant Power Supply wtih PoE

The N50 features dual Gigabit Ethernet ports, one supporting PoE for combined power and network over a single cable.
The dual network port design provides primary-backup redundancy. If the primary port fails, the backup port ensures service continuity. Additionally, these ports support bonding function, allowing different network to share data transmission—ensuring uninterrupted video streaming.​

Fast and Easy PTZ Control

The N50 supports controlling external PTZ camera via USB to serial (RS-232/RS-485/RS-422) or over network protocols such as VISCA, VISCA over IP, and Pelco. It enables precise adjustment of pan, tilt, and zoom, making it ideal for studios, conferences, live events, and other professional scenarios with easy operation and fast response.

Flexible Storage Options

The N50 offers three flexible recording options:
• Local TF card storage
• USB external drives
• Network-attached storage (NAS)
Recording format, mode, and file splitting can be customized for both local (TF card/USB) and NAS storage, with support for MOV and MP4 formats.

*Note: Some USB drives may not be supported if their power requirements exceed the N60’s output capacity.

Real-Time Voice Communication for Efficient On-Site Coordination

The N50 supports USB-connected microphones and headsets when integrated with Kiloview’s KIS intercom system to enable instant voice communication and seamless remote collaboration——ideal for live directing, remote production, and mobile reporting.

Centralized Management with Kilolink Server Pro

The N50 seamlessly connects to the KiloLink Server Pro once registered, enabling centralized remote management with real-time monitoring of device status, including connectivity, video preview, bandwidth, and IP address—all in one interface for streamlined oversight.

Visual Input Loss Alerts for Instant Issue Identification

When an input signal is lost during encoding, or when a network source becomes unavailable during decoding, 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 identify signal issues, minimizing downtime and avoiding confusion.

Compact Design with Easy Camera Mounting

The N50 features a compact design and comes with a standard threaded cold shoe mount, making it easy to attach directly to a camera.
