PDAF Autofocus 4K PC Web Camera 1/2.8 Inch Sensor Desktop Conference Room Webcam

This PDAF autofocus 4K PC web camera is engineered with an advanced 1/2.8 inch optical image sensor, ensuring precise visual data acquisition for professional desktop environments. The hardware is strictly calibrated to support a maximum effective pixel matrix of 3840(H) multiplied by 2160(V). The USB video camera provides continuous 4K video broadcasting at exactly 30 frames per second, and offers an additional 1080P video mode at 60 frames per second for high-refresh-rate streaming requirements. The physical pixel architecture of the sensor measures exactly 1.4 micrometers by 1.4 micrometers, preserving precise visual details. The camera processes optical input natively in standard YUY2 and MJPEG formats. The hardware operates with a tested dynamic range measuring 70db.

To maintain optimal image clarity, the 4K video camera utilizes a specialized 6-element (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 precisely controls the focusing function. The PDAF system allows the desktop camera to focus instantly on moving subjects without the mechanical hunting delays associated with contrast-based mechanisms. The optical lens provides a specific angular field of view of 83 degrees with a ±1 degree tolerance.

Audio input on this PC webcam is managed by integrated 2 channel stereo noise-canceling microphones. A custom physical privacy cover is provided to securely block the optical 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 active operational status, and the specifications confirm the absence of a built-in beauty light.

Structurally, the 921MAX model is designed to sit securely on computer monitors or flat desks. The precise physical dimensions measure 85 millimeters in total width, 52.4 millimeters in main body height, and 62.87 millimeters in depth. The hardware is broadly compatible with multiple operating systems, providing driver-free plug-and-play support for Windows 7, Windows 8, Windows 10, Windows 11, Mac OS, Linux, Android, and Ubuntu platforms.

The specified working temperature for the computer camera ranges safely 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 effectively within a relative humidity limit of less than or equal to 80 percent. Standard assembly guidelines mandate anti-static handling procedures and strict protection against heavy physical pressure during transport and construction.
