4K60 SDI/HDMI PTZ Camera with 12X-20X Zoom
Add a high-resolution streaming and tracking camera to your lecture room, house of worship, or conference room for remote meetings with software such as Skype, Microsoft Teams, or Zoom with Winkomm WK-750 4K60 SDI/HDMI PTZ Camera. The Winkomm WK-750 4K PTZ Camera captures resolutions up to UHD 4K60 via IP and HDMI, 1080p60 over 3G-SDI, and it features auto-tracking for presentations where your subject moves around the room, great for education, how-to, and corporate environments without the need for an operator. Its wide dynamic range, 3D noise reduction, and low-bandwidth, high-quality NDI|HX 2 capabilities provide a sharp, consistent image, even in low light.
The WK-750 series 4K PTZ camera’s features include a 1/2.5” CMOS for 12X and 1/1.8″ 4K CMOS 8.42MP sensor for 20X for crisp imagery. The built-in zoom lens has an optical zoom range of 12X/20x, and you can zoom in further with up to 16x digital zoom. With 255 programmable preset positions via serial, you can set the camera to rapidly move between positions using IP, RS-232, or RS-485 with separately available controllers, or by using IR control with the included remote. It also features a tally light. The video output is compressed using H.265, H.264, or MJPEG formats, and you can transmit up to two simultaneous streams using SRT, RTSP, and RTMP protocols.
The camera supports external audio input via a 3.5mm stereo line-level jack for embedding audio into your stream, and a 3.5mm audio output. Power is provided by the included AC adapter or via PoE+ (Power-over-Ethernet) on a supported network.
Multiple Interfaces
WK-750 4K PTZ Cameras support outputs include HDMI 2.0, 3G-SDI, Wired LAN, IP Streaming (RTMP, RTSP, SRT) and USB3.0 (optional). The 3G-SDI will wok up to 100 meters in distance.
4K60 Resolution
The WK-750 4K PTZ camera captures resolutions up to UHD 4K60 via IP and HDMI, 1080p60 over 3G-SDI. Downward compatible with 1080P, 720P and other resolutions.
3.5mm Line Stereo In
WK-750 4K camera supports external audio input via a 3.5mm stereo line-level jack for embedding audio into your stream.
NDI|HX2 Compatible
The NDI protocol, NewTek’s innovative IP technology, gives you low-latency access to audio and video devices anywhere on your network for various A/V applications. You won’t be restricted to sources connected directly to a single system.
Super Quiet PTZ
Whisper-quiet mechanical PTZ motor adjusts pan and tilt speed with the amount of zoom. The result: Faster camera movement when zoomed out for quick framing and slower camera movement when zoomed in for more control.
AI Tracking
The embedded NPU hardware leverages deep learning technology to identify and extract the relevant features of a target, enabling seamless tracking of faces regardless of their orientation. This product is particularly useful for automatically tracking speakers during lectures and presentations.
