Atomos A-Eye 4K-20X PTZ Camera

Twenty metres between lens and stage is routine territory for the Atomos A-Eye 4K-20X PTZ Camera. Its 20x optical zoom (6.25–125 mm, F1.58–F3.95) closes that distance without losing detail, while the 1/1.8-inch CMOS sensor with 8.42 megapixels reads out UHD 3840 x 2160 at up to 60 frames per second. AI auto-tracking keeps a moving presenter framed across the full ±170° pan and −30° to +90° tilt range, so a keynote, panel or award ceremony runs without a dedicated operator. Light falling to 0.5 lux? The picture stays usable, backed by 2D/3D noise reduction and a signal-to-noise ratio above 55 dB.

Signal distribution is where this model earns its rack space. NDI|HX3 comes pre-licensed and moves low-latency 4K across ordinary Ethernet, while SRT, RTMP/RTMPS, RTSP, ONVIF and multicast handle contribution to CDNs, decoders and remote galleries. HDMI outputs 4Kp60 to a local switcher, 3G-SDI feeds 1080p60 into existing vision mixers over long BNC runs, and the USB port registers as a UVC source in Zoom, Teams, OBS or vMix — it even records directly to an external drive for an independent backup copy.

Cabling stays minimal. With PoE+ (802.3at), one network cable carries power, video and control, and consumption never passes 18 W. Operators can pick VISCA over IP, the included remote, or RS-232 and RS-485 serial lines reaching 30 m and 1,200 m, with Pelco-D/P compatibility for mixed camera fleets. 255 presets recalled at 0.1° accuracy make rehearsed moves repeatable night after night, and pan speeds up to 100°/s reposition the head between shots in moments.

For a production company covering hybrid conferences, sports, lecture capture or multi-camera live streaming, the A-Eye 4K-20X brings reach, tracking intelligence and open standards together in a housing that mounts upright, inverted or on the supplied wall bracket. Sound from a mixing desk enters through the 3.5 mm line input and stays embedded in every output, and a tally lamp tells talent which camera is live.
