USB 2.0 Conference Webcam 4K 30FPS 1/2.8 Inch Sensor Desktop PC Cam 921MAX

This USB 2.0 web camera is built with an advanced 1/2.8 inch optical image sensor, ensuring high light sensitivity and accurate visual data acquisition for desktop use. The internal sensor hardware supports a maximum effective pixel matrix of 3840(H) by 2160(V). The desktop PC cam delivers continuous 4K video resolution at a steady 30 frames per second. For scenarios requiring higher frame rates, it offers an alternative 1080P output operating at 60 frames per second. The internal pixel structure is strictly measured at 1.4 μm by 1.4 μm. Video streams are encoded and processed in standard YUY2 and MJPEG formats. The optical hardware operates with a tested dynamic range of 70db.

The optical path features a 6-element (6P) glass lens assembly. The lens incorporates an F2.0 aperture and a focal length of 4.25. The total optical length of this component is strictly measured at 5.35. The field of view is factory-calibrated to 83 degrees with a tolerance of ±1 degree. For focusing, the camera uses Phase Detection Auto Focus (PDAF) technology. This PDAF integration ensures the computer camera calculates spatial depth instantly, avoiding the mechanical hunting effects seen in older contrast-based autofocus mechanisms.

Audio communication on this desktop video camera relies on integrated 2 channel stereo noise-canceling microphones. To ensure user privacy, a dedicated privacy cover is included in the hardware design. The hardware links to the host PC via a standard USB 2.0 communication protocol. This ensures the USB web camera maintains stable bandwidth for 4K video transmission. The device operates on a standard DC 5V voltage and requires a maximum working current of 370mA. A working indicator light illuminates to signify when the camera is active, and the specification confirms the absence of a beauty light.

The structural dimensions of the 921MAX camera body are 85 millimeters wide, 62.87 millimeters deep, and 52.4 millimeters high. System compatibility includes driver-free plug-and-play support for Windows 7, Windows 8, Windows 10, Windows 11, Linux, Android, Ubuntu, and macOS.

The PC video camera operates safely within ambient working temperatures from 0 to 60 degrees Celsius. Storage specifications range between -30 and 85 degrees Celsius. The device is engineered to function within a relative humidity environment of ≤80 percent. Standard assembly guidelines mandate anti-static handling and protection against heavy physical pressure during transport.
