1/2.8 Inch Sensor Computer Camera 4K USB 2.0 Web Cam Dual Mic 921MAX

This 1/2.8 inch sensor computer camera is engineered for high-definition desktop communication, utilizing an advanced optical image sensor. The hardware supports a massive maximum effective pixel matrix of 3840(H) by 2160(V). The USB video camera provides continuous 4K video broadcasting at 30 frames per second, and an additional 1080P video mode at 60 frames per second for high-refresh-rate streaming. The physical pixel architecture of the sensor measures exactly 1.4 μm by 1.4 μm, preserving precise visual details. The camera processes optical input natively in standard YUY2 and MJPEG formats. The hardware operates with a wide dynamic range measuring 70db.

To maintain image clarity, the 4K video camera uses a 6P glass composition lens. 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 hardware includes a PDAF (Phase Detection Auto Focus) module that controls the focusing function. The PDAF system allows the desktop camera to focus quickly on moving subjects without contrast-based delays. The lens provides a specific angular field of view of 83 degrees ±1 degree.

Audio input on the PC webcam is managed by integrated 2 channel stereo noise-canceling microphones. A custom privacy cover is provided to securely block the lens when the camera is not actively used. The data connection is established through a standard USB 2.0 interface. This USB port ensures that the 4K resolution camera can transmit video data with high stability to the host computer. The streaming webcam is designed to operate on a DC 5V power supply, drawing a maximum working current of 370mA. A working light is incorporated into the front panel to indicate operational status, and the device operates without a built-in beauty light.

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. The hardware is broadly compatible with multiple operating systems, providing driver-free support for Windows 7, Windows 8, Windows 10, Windows 11, Mac OS, Linux, Android, and Ubuntu.

The specified working temperature for the computer camera ranges from 0 to 60 degrees Celsius, while the recommended storage temperature is strictly defined between -30 and 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.
