Presenter tracking
Power over Ethernet
P20i is a 1080p AI tracking PTZ camera with 20× optical zoom. It suits medium and large classrooms, lecture halls, auditoriums and houses of worship. With AI tracking on, the camera follows the presenter by itself and nobody has to operate it.
01AI auto tracking
Wherever the presenter goes, the camera follows.
AI person tracking is built in, with no extra computer or software. When the presenter walks across the stage or turns to the whiteboard, the camera keeps up.
0220× optical zoom
One camera at the back of the hall is enough for close-ups.
With 20× optical zoom the tele end narrows to a 3.36° horizontal view, so a camera at the back of a classroom or hall still shows the presenter's expression. The 60.7° wide end covers the whole stage.
03HDMI, SDI, USB and network
Ready for meetings, recording and streaming.
HDMI and 3G-SDI feed a switcher or recorder; USB 3.0 connects to a computer for video meetings; the network output supports RTSP, RTMP and SRT for direct streaming. Line In and Line Out bring the room audio along.
04Installation and control
Easy to mount, easy to fit into what you have.
PoE (802.3af) powers it over a single network cable. It can be mounted upside down and a ceiling bracket is included. Control it with the remote, RS-232, RS-485, VISCA over IP, ONVIF or a CAVE K10 or K20 keyboard, with up to 255 presets.
05With a recorder and a keyboard
Close-up, wide shot and slides, recorded together.
A common setup in classrooms and lecture halls: a P20i at the back covers the presenter, a second camera takes the wide shot, and both go into an NSR recorder with the presentation computer, switched from a K10 or K20 keyboard. The lesson is recorded and streamed as it happens.

No. AI tracking is built into the camera, with no computer or software to add. Once it is on, the camera follows the presenter as they walk the stage or turn to the whiteboard.
Can P20i be used for live streaming?
Yes. Its network output supports RTSP, RTMP and SRT for streaming directly. HDMI and 3G-SDI connect to a switcher or a recorder, and USB 3.0 connects to a computer for video meetings.
Can P20i be mounted upside down?
Yes. P20i supports upside-down mounting and a ceiling bracket is included. It supports PoE (802.3af), so on a ceiling one network cable can power it.
