The Smallest Way to 4K NDI

The BirdDog Flex 4K In is a revolutionary, credit-card-sized interface that brings professional 4K HDMI sources into the world of Full NDI. Weighing under five ounces, it is designed to mount directly onto your camera or monitor rig without adding bulk. It transforms any HDMI camera into an instantly recognizable NDI source on your network, delivering pristine UHD 4K30 or high-frame-rate 1080p60 video with ultra-low latency.

A Complete Power Solution

Beyond signal conversion, the Flex 4K acts as a power management hub for your entire camera setup. When powered via PoE (Power over Ethernet), the unit can utilize its DC barrel output to provide up to 15W of power to select monitors or cameras. This "Single Cable" philosophy significantly reduces cable clutter, allowing you to run your video, power, tally, and comms through one lightweight Ethernet line.

Advanced Cooling and Tally Integration

High-resolution encoding generates heat, but the Flex 4K is built to handle it. Its innovative thermal design and whisper-quiet fans ensure the unit stays cool and stable during long broadcast days, even in hot environments. For live production, the integrated tally light is strategically positioned to be seen by both the person behind the lens and the talent in front of it, ensuring everyone knows exactly when the feed is live.

Expandable Control and Software Tools

The Flex 4K is more than a converter; it’s a "PTZ Sidekick." By using a separately available cable, you can pass through control signals to non-NDI PTZ cameras, bringing older hardware into a modern IP workflow. Every Flex 4K includes access to BirdDog’s powerful software suite, including Central Lite for routing, Dashboard for configuration, and Comms Lite for professional-grade audio intercom.
