BFKK K820N 4K NDI PTZ Camera

The BFKK K820N is a professional PTZ camera built for live production in houses of worship, education, conference and event venues. It combines a 1/1.8-inch UHD CMOS sensor with an Ambarella 4K AI chip to deliver simultaneous video over four output channels. The unit includes an official NDI licence approved by Newtek and supports NDI | HX2 and NDI | HX3 for low-latency IP workflows.

8.42MP 1/1.8-inch CMOS sensor with 20X optical zoom

The camera centres on an 8.42MP 1/1.8-inch UHD CMOS sensor paired with a 20X optical zoom lens covering a 60-degree maximum field of view. This combination determines the reach and low-light capability for wide auditoriums or tight podium shots. Output formats include 4K at 60, 59.94, 50 and 30 fps over HDMI 2.0 and LAN, 4K at 30 fps over USB 3.0, and 1080p at up to 60 fps over 3G-SDI.

PoE power with gravity-sensor auto-flip

Power over Ethernet allows a single LAN cable to supply power, control and streaming, reducing cabling in fixed installs. A built-in gravity sensor enables automatic image flip for ceiling or desktop mounting without menu changes. AI face and body tracking is engaged from the remote control, letting operators switch tracking targets instantly during a live event.
