This PDAF computer camera is built upon an advanced 1/2.8 inch optical image sensor, ensuring high light sensitivity and accurate visual capture. The hardware is strictly calibrated to support a maximum effective pixel matrix of 3840(H) by 2160(V). The USB webcam maintains a continuous recording capability of 4K resolution at 30 frames per second, while also providing a 1080P output mode operating at 60 frames per second. The physical pixel dimension is engineered at 1.4 μm by 1.4 μm to ensure crisp image granularity. The streaming PC camera outputs video data natively in industry-standard YUY2 and MJPEG formats. The optical sensor maintains a tested dynamic range measuring 70db.
The optical path utilizes a dedicated 6-piece (6P) glass lens structural assembly. This lens system is combined with an F2.0 aperture and a focal length of 4.25. The total optical length is strictly specified at 5.35. The camera field of view is factory-set to an 83-degree angle with a ±1-degree tolerance. Focusing is entirely managed by Phase Detection Auto Focus (PDAF) technology. This PDAF module allows the desktop video camera to calculate subject distance rapidly, providing continuous sharpness without software-based autofocus latency.
Vocal inputs on this video conference camera are processed by integrated 2 channel stereo noise-canceling microphones. A dedicated privacy cover is integrated into the design to physically block the optical lens. The hardware interfaces with host computers via a standardized USB 2.0 connection protocol. Operating on a standard DC 5V voltage, the device requires a maximum working current of 370mA. A working light is visible on the front chassis to indicate active operation. The hardware layout confirms the absence of a built-in beauty light.
The hardware enclosure of the 921MAX model measures 85 millimeters in width, 62.87 millimeters in depth, and reaches a height of 52.4 millimeters. This USB video camera provides extensive system compatibility, operating seamlessly without drivers on Windows 7, Windows 8, Windows 10, Windows 11, Linux, macOS, Android, and Ubuntu.
The internal electronics are rated for a safe working temperature spanning 0 to 60 degrees Celsius. Storage parameters dictate an environment between -30 and 85 degrees Celsius. The hardware is designed to operate reliably in environments with a relative humidity of ≤80 percent. Manufacturing guidelines state that the device requires anti-static handling and must be protected from heavy pressure during the assembly process.
