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

Small is the new Big.
With a footprint only slightly larger than a credit card, the Flex 4K NDI Encoders and Decoders are the smallest on the planet. 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 an unmatched thermal design and whisper quiet fans to keep Flex cool and fresh at all times. Even on the hottest of 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.

The ultimate PTZ sidekick.
If you aren’t lucky enough to own a BirdDog PTZ camera with Full NDI natively, then Flex is your ultimate sidekick. Plug in HDMI to encode Full NDI, and attach the optional PTZ control cable to have complete PTZ control. Perfect upgrade for your PTZ camera while waiting for Santa to bring you a BirdDog PTZ.

G’Day Dante.
Flex 4K NDI family can support Dante input and output via the 3.5mm audio jack. 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. Soy based ink is used to further reduce our environmental footprint. There are no printed manuals inside the box to save paper. Of course you can download the most up to date version anytime from our website.

Camera Mount.
The optional camera mount adds a 1-4”/20 female thread for mounting onto ball heads and magic arms to pimp your rig the way you want it.

RESTful API. DIY automation.
