12MP Resolution USB 2.0 Webcam 4K 30FPS F1.7 Lens Video Camera 874L

Designed for high-definition desktop communication, this 12MP resolution USB 2.0 webcam utilizes an advanced 1/2.5 inch optical image sensor. The hardware is engineered to support a massive maximum effective pixel matrix of 4000(H) multiplied by 3000(V). The video camera provides highly stable video broadcasting at 4K resolution and 30 frames per second, with an additional 1080P mode operating at 60 frames per second. The sensor features a precise pixel dimension of 1.4 μm by 1.4 μm, ensuring excellent image granularity. Video streams are natively encoded in MJPEG and YUY2 data formats. The optical sensor maintains a wide dynamic range of 70db.

The optical path features a dedicated 6-element (6P) glass lens construction. This lens array incorporates a large F1.7 aperture, allowing the PC cam to maximize light transmission and maintain clear video quality in dimly lit rooms. The camera projects a specifically calibrated angular field of view of 77 degrees ±1 degree. The device utilizes Phase Detection Auto Focus (PDAF) technology. This advanced PDAF integration ensures the computer camera focuses almost instantaneously on subjects without mechanical hunting delays.

This desktop video camera introduces dual-sided touch interactivity. The left side features a touch key that cycles through brightness adjustments, and the right side features a touch key that controls progressive hardware zooming. Both interactions trigger a blue LED light confirmation. Audio recording is managed by built-in 2 channel stereo noise-canceling microphones. To protect personal privacy, the camera includes a premium magnetic privacy cover that attaches securely over the lens when not in use.

Data communication with host computers is established via a standard USB 2.0 interface. Operating on a standard DC 5V current, the computer web camera requires a remarkably low maximum working current of just 190mA, ensuring high energy efficiency. A central indicator light illuminates specifically when the device is actively outputting a video feed.

The physical chassis of the 874L model camera measures 74.9mm in total width and 46mm in main body height. The device supports universal driver-free operation across Windows 7, Windows 8, Windows 10, Windows 11, macOS, Linux, Android, and Ubuntu systems. The internal components are rated for continuous operation within a temperature range of 0 to 60 degrees Celsius. The recommended storage environment is strictly specified between -30 and 85 degrees Celsius.
