PDAF Focus 4K Web Camera Touch Adjustable Brightness PC Webcam 874L

This PDAF focus 4K web camera features an advanced 1/2.5-inch optical image sensor, ensuring high light sensitivity and professional video capture. The device outputs video data at a maximum effective resolution of 4000(H) by 3000(V). It maintains a steady 4K resolution video feed at 30 frames per second, while also providing a 1080P output option at 60 frames per second. With an internal pixel dimension of 1.4 μm by 1.4 μm, the sensor preserves highly precise visual details. Video streams are natively encoded in MJPEG and YUY2 formats. The hardware is tested to support a broad dynamic range measuring 70db.

The optical path relies on a 6P glass lens structure. This dedicated lens assembly is paired with an exceptionally large F1.7 aperture, which enables the PC webcam to record bright images even in challenging indoor lighting. The angular field of view captures 77 degrees diagonally with a tolerance of ±1 degree. The camera utilizes Phase Detection Auto Focus (PDAF) technology. This advanced PDAF capability calculates spatial depth instantly, avoiding the mechanical readjustment delays found in traditional autofocus cameras.

Interactive functionality is provided through dual touch controls located on the camera chassis. Tapping the left touch sensor cycles through brightness levels to optimize exposure, while the right touch sensor triggers a hardware-level zoom magnification. Both touch sensors activate a corresponding blue LED light upon use. Audio capture on this desktop video camera is managed by integrated 2 channel stereo noise-canceling microphones. A premium magnetic privacy cover is supplied to block the optical lens when not actively broadcasting securely.

The hardware establishes data communication with computers via a standard USB 2.0 interface, ensuring reliable bandwidth for 4K streams. Operating on a standard DC 5V voltage, the computer web camera is highly energy-efficient, requiring a maximum working current of only 190mA. An integrated central indicator light confirms when the device is outputting video data.

The physical dimensions of the 874L camera body are 74.9 millimeters in total width and 46 millimeters in height. The device offers broad system compatibility, requiring no drivers to operate on Windows 7, 8, 10, 11, Linux, macOS, Android, and Ubuntu platforms. The PC video camera functions safely within ambient temperatures from 0 to 60 degrees Celsius, with recommended storage temperatures between -30 and 85 degrees Celsius.
