12MP USB Video Camera PDAF Autofocus 4K Resolution Desktop Webcam 874L

This 12MP USB video camera is constructed using an advanced 1/2.5 inch optical image sensor. The integration of this large sensor provides the desktop video camera with high light-gathering capabilities. The hardware supports a maximum of 4000(H) x 3000(V). The USB camera supports a 4K video format at a frame rate of 30fps and a 1080P video format at 60fps. The pixel architecture of the sensor measures exactly 1.4μm by 1.4μm. The camera hardware processes the optical input and outputs data in standard YUY2 and MJPEG formats, with a dynamic range of 70db.

To maintain image clarity, the 4K desktop camera uses a 6P glass composition lens. This optical configuration is paired with an exceptionally large F1.7 aperture, enabling the USB web camera to capture precise visual details even in poor lighting. The hardware includes a PDAF (Phase Detection Auto Focus) module that controls the focusing function. The PDAF system allows the video calling camera to focus quickly on moving subjects. The lens provides a specific angular field of view of 77 degrees ±1 degree.

The device incorporates dual touch controls for hardware-level adjustments. A left touch button regulates the image brightness in a continuous loop. A right touch button manages the camera's zoom capabilities. Each touch action activates a blue LED indicator. For audio recording, the desktop video camera is equipped with 2 channel stereo noise-canceling microphones. A premium magnetic privacy cover is provided to securely block the 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. The USB video camera is designed to operate on a DC5V power supply, drawing a remarkably low maximum working current of just 190mA. A central indicator light signals when the image output is active.

The hardware is broadly compatible with multiple operating systems, including Windows 7, Windows 8, Windows 10, Windows 11, Mac OS, Linux, Android, and Ubuntu. The specified working temperature for the computer camera ranges from 0 to 60 degrees Celsius, while the recommended storage temperature is between -30 and 85 degrees Celsius. The physical dimensions of the 874L main camera body are 74.9 millimeters in width and 46 millimeters in height.
