Desktop Video Camera 4K UHD 1/2.8 Inch 83 Degree FOV PC Webcam 921MAX

This desktop video camera is fundamentally built around an advanced 1/2.8 inch optical sensor, engineered to deliver precise visual data processing. The hardware supports a maximum effective pixel matrix of 3840(H) by 2160(V). The USB web camera maintains a consistent broadcast capability of 4K resolution at 30 frames per second. Additionally, the device is capable of outputting a 1080P resolution stream at 60 frames per second. The pixel architecture of the sensor measures exactly 1.4μm by 1.4μm. The camera hardware processes the optical input and outputs video data natively in standard YUY2 and MJPEG formats. The system operates with a measured dynamic range of 70db.

The optical assembly features a customized 6P glass lens construction. This specific structural lens assembly operates with an F2.0 aperture and a focal length of 4.25. The total optical length is strictly calibrated to 5.35. The resulting field of view is wide yet highly controlled, capturing an 83-degree angle with a tolerance of ±1 degree. The camera utilizes Phase Detection Auto Focus (PDAF) technology. This PDAF approach guarantees that the streaming PC camera focuses quickly and accurately on subjects, avoiding the readjustments seen in older autofocus methodologies.

Audio input on the PC webcam is managed by integrated 2 channel stereo noise-canceling microphones. The hardware establishes a connection to computing devices using the standard USB 2.0 protocol. The computer web camera operates on a DC 5V current and demands a maximum working current of 370mA. A working light is incorporated into the front panel to indicate operational status. The specification sheet confirms the device does not feature a beauty light. The camera includes a privacy cover to physically block the lens.

Structurally, the 921MAX model is designed to sit securely on monitors or desks. The physical dimensions measure 85mm in width, 52.4mm in height, and 62.87mm in depth. Environmental and system compatibility is broad. The PC camera functions natively across Windows 7, 8, 10, 11, Linux, macOS, Android, and Ubuntu.

The device is engineered to operate safely in ambient working temperatures ranging from 0 to 60 degrees Celsius. When not in use, the recommended storage temperature range is -30 to 85 degrees Celsius. The hardware is tested to operate within a relative humidity limit of ≤80 percent. Standard assembly guidelines mandate anti-static handling and protection against heavy pressure during transport and construction.
