4K UHD Desktop Camera 921MAX PDAF Autofocus 1/2.8 Inch Sensor USB 2.0

This 4K UHD desktop camera is engineered around an advanced 1/2.8-inch optical image sensor, delivering exceptional light sensitivity for professional digital environments. The internal hardware supports an ultra-high maximum effective pixel resolution of 3840(H) multiplied by 2160(V). The device consistently delivers 4K video at 30 frames per second, with an optional 1080P output at 60 frames per second for high-motion capture. The image sensor utilizes a precisely calibrated pixel size measuring 1.4 micrometers by 1.4 micrometers. Raw visual data is efficiently encoded and transmitted using industry-standard YUY2 and MJPEG formats. The optical system maintains a tested dynamic range of 70db.

The optical mechanism of this USB webcam features a specialized 6-element (6P) glass lens composition. This lens array incorporates an F2.0 aperture and a focal length of 4.25. The total optical length is strictly measured at 5.35. The angular field of view is factory-calibrated to 83 degrees, providing a balanced framing area with a strict tolerance of ±1 degree. For focusing, the camera utilizes Phase Detection Auto Focus (PDAF) technology. This advanced PDAF mechanism allows the PC camera to calculate spatial depth instantly and lock focus on subjects with zero mechanical hunting delays.

Audio recording is managed by built-in 2 channel stereo noise-canceling microphones. For physical security, the camera chassis is equipped with a dedicated privacy cover. A working light indicator is integrated into the front panel to signal active data transmission. The device specifications state that it does not include a built-in beauty light component. Connectivity is established through a standard USB 2.0 interface.

The streaming PC camera operates on a DC 5V power supply and requires a maximum working current of 370mA. The physical structure of the 921MAX webcam is designed for monitor stability, measuring 85 millimeters in total width, 52.4 millimeters in main body height, and 62.87 millimeters in depth. The device supports universal plug-and-play functionality across Windows 7, Windows 8, Windows 10, Windows 11, macOS, Linux, Android, and Ubuntu systems.

The internal electronics are rated to operate safely within an ambient working temperature range of 0 to 60 degrees Celsius. Recommended storage temperatures are specified from -30 to 85 degrees Celsius. Environmental specifications dictate a relative humidity of less than or equal to 80 percent. During assembly and transportation, the hardware requires anti-static treatment and must not be subjected to heavy physical pressure.
