LU 400Broadcast-Quality, lightweight field Unit.

Powered by LiveU’s multi-processor video encoding engine and weighing around 700g (25oz), LiveU’s LU400 represents a highly cost-effective, portable and robust HD video uplink device. LU400 is available in various configurations including belt-clip or camera-mount.

The LU400 offers a wide range of features and capabilities for live news gathering, including: low latency for interview-mode; Store & Forward; file transfer (FTP); video and audio indicators; under one minute boot-up time and the ability to control the unit from its touch screen, the server or from any web enabled device.

With proprietary internal antennas, the LU400 provides resilient live HD video transmission for 24/7 news and events coverage on-the move and in fixed locations, optimizing all available bandwidth to deliver broadcast quality video. The LU400 offers up to 7 bonded connections, including four internal cellular modems, WiFi, two LAN connections and two external USB ports.

The LU400 is fully integrated with LiveU’s video ecosystem which includes: front-end field acquisition cellular bonding products, back-end servers, the LiveU Central management platform, and cloud based IP services, allowing full configuration, control and monitoring of the entire ecosystem and content via any browser-supported device.
