Stream-ready 4K PTZ camera

The PTZOptics Link 4K is a white pan-tilt-zoom camera built for classrooms, houses of worship and conference rooms that need UHD 4K60 capture over IP, HDMI or 3G-SDI. Its 1/2.5" 8.51MP CMOS sensor and 12x optical zoom lens cover a 6.9 to 72.5° angle of view for wide shots or tight detail. Auto-tracking follows a presenter without an operator, while 16x digital zoom extends reach when needed.

Silent operation, low heat

The compact enclosure runs cool and quiet during long sessions, making it suitable for environments where fan noise would distract participants. Power is supplied through the included adapter, and the camera draws modest current typical for fixed-installation PTZ units. No active cooling vents face the audience, so thermal output stays unobtrusive in small meeting spaces.

Flexible mounting and control

Threaded mounting points allow wall, ceiling or tripod installation, and the 3.5mm stereo audio in/out jacks sit beside HDMI, 3G-SDI and USB 2.0 ports for simple cabling. RS-232, RS-485 and IP control let operators recall any of 255 presets from a hardware joystick, software interface or the supplied IR remote. Dante AV-H, SRT, RTMPS and RTSP support integrates the camera into existing AV-over-IP workflows without extra converters.

Questions about this item

How do I mount the Link 4K and set the 255 presets without a controller?

Mount the camera on a standard tripod or ceiling bracket, connect power and network, then use the included IR remote to pan, tilt, zoom and store up to 255 preset positions directly from the handset.

What routine upkeep does the 1/2.5" 8.51MP sensor and 12x optical zoom lens require?

Wipe the front glass with a dry microfibre cloth when dust appears; the sealed zoom mechanism has no user-serviceable parts and needs no lubrication or scheduled replacement.

At what point does the 3G-SDI output limit resolution during a long 4K60 stream?

The 3G-SDI port caps at 1080p60, so extended 4K60 sessions must use HDMI or IP streaming instead to maintain full UHD resolution.
