12MP Computer Camera F1.7 Aperture Touch Zoom Magnetic Cover Webcam 874L

This 12MP computer camera is built upon an advanced 1/2.5 inch optical sensor, engineered to acquire visual data with extreme precision. The hardware is strictly calibrated to support a maximum effective pixel matrix of 4000(H) by 3000(V), providing highly detailed video outputs. The USB webcam maintains a continuous recording capability of 4K at 30 frames per second, while also offering a 1080P mode at 60 frames per second to capture fast-paced movements smoothly. The physical pixel dimension is structured at 1.4 μm by 1.4 μm to ensure crisp image granularity. The optical system operates with a measured dynamic range of 70db, processing video streams natively in YUY2 and MJPEG formats.

The optical path of this streaming camera utilizes a 6-element (6P) glass lens construction. This specific lens assembly features a remarkably large F1.7 aperture, which allows the desktop camera to absorb significantly more light than standard lenses. The resulting angular field of view is 77 degrees with a tolerance of ±1 degree. The focusing mechanism relies on Phase Detection Auto Focus (PDAF). This PDAF integration ensures the PC web camera focuses on subjects almost instantaneously, eliminating the blurring effects associated with traditional contrast-based focusing systems.

This video conference camera introduces dual-sided touch interactivity. Users can tap the left touch key to cycle through brightness adjustments, while the right touch key controls a hardware-level image zoom function. A blue LED flashes to confirm each successful touch input. Vocal inputs are processed by integrated 2 channel stereo noise-canceling microphones. To protect user privacy, the camera is equipped with a custom magnetic privacy cover that snaps firmly over the lens when not in use.

Data communication with host computers is managed via a USB 2.0 protocol. Operating on a standard DC 5V current, the computer web camera requires a remarkably low maximum working current of 190mA, making it a highly energy-efficient peripheral. A dedicated central indicator light illuminates specifically when the device is actively outputting an image.

The physical chassis of the 874L model measures 74.9mm in width and 46mm in height, featuring a sturdy mounting base designed for monitors. The device functions without requiring drivers across Windows 7, 8, 10, 11, macOS, Linux, Android, and Ubuntu. The internal components are rated for continuous operation within a temperature range of 0 to 60 degrees Celsius. The recommended storage environment is specified between -30 and 85 degrees Celsius.
