Rated 5 out of 5

Great Little box.

Got mine a few weeks ago and works great. I did have an issue at a recent event whereby the 4k feed worked in rehearsals but didn't work the day of the show. I think it may have been due to long cat7 run alongside the light board cable and some electric cables. I'm pretty sure the cat7 I purchased was shielded though. Buy the mount for a few dollars more as you need it.

Birddog NDI Flex Out

BirdDog Flex 4K.

The Smallest NDI on the Planet.
4K NDI in an incredibly small package. Flex delivers everything you have come to expect from BirdDog's one cable solution including Tally, Audio, Video, PTZ Control, Audio Intercom and Power along a single Ethernet cable. With 3 models to choose from in the Flex Family, Flex is perfect for all your workflow needs.

Small is the New Big.
With a footprint only slightly larger than a credit card, Flex are the world's smallest 4K NDI Encoders and Decoders. Because sometimes the biggest things are also the smallest.

Cool touch thermals.
Sometimes the biggest features are also the least obvious. Flex 4K NDI has unmatched thermal design and whisper quiet fans to keep Flex cool and fresh even on the hottest days and in direct sunlight.

Halo Tally. It just works.
Flex's revolutionary Halo Tally system is built right into the Flex Family and requires zero configuration when connected with any NDI enabled, software based, production system. The Halo Tally is designed to be seen by the camera operators as well as the on-air talent.

Adaptive bit rate. Slide your way to glory.
Full NDI is a variable bit rate codec. In normal circumstances BirdDog recommends allowing around 140Mbps in HD, or 6 streams per 1GbE cable with some headroom. In 4K it is recommended to allow around 300Mbps or 3 streams with some headroom to allow for any unforeseen spikes.

Flex's revolutionary Halo Tally system

The Ultimate PTZ Sidekick.
If you aren't lucky enough to own a BirdDog PTZ camera with Full NDI natively then Flex can become the ultimate sidekick. Plug your PTZ camera into Flex via HDMI, attach the optional BirdDog PTZ control cable for full PTZ pass through control. This makes Flex the perfect upgrade for your PTZ camera while waiting for Santa to bring you a Full NDI BirdDog PTZ.

G'Day Dante.
Flex 4K NDI family can support Dante input and output via the 3.5mm audio jack or the HDMI input on Flex IN and Flex BACKPACK. Flip Dante out of the NDI stream or embed Dante into the NDI stream. The choice is yours.

100% Recyclable packaging. We love Pachamama.
Every element of Flex packaging is 100% recyclable and we use soy based ink to further reduce our foot print. There are no printed manuals, you can download the most up to date version at any time from our website.

Comms Lite.
Flex 4K Family includes free Comms Lite, your free Audio Intercom solution. With support for four BirdDog devices, plus a director, Comms Lite is a great way to start using Audio Intercom in your live productions.

RESTful API. DIY automation.
Download the free BirdDog RESTful API and program your own automation for all BirdDog hardware endpoints, including cameras.

Central Lite.
Flex 4K Family includes free Central Lite NDI Routing software. Team up Central Lite with any NDI source, including all BirdDog hardware capable of creating NDI sources, you can now drive your NDI streams to any BirdDog Studio NDI or Mini to decode NDI back to SDI or HDMI.
