Touch Control PC Webcam 1/2.5 Inch Sensor PDAF 4K Video Camera 874L

This touch control PC webcam is constructed using an advanced 1/2.5 inch optical image sensor, ensuring high-fidelity visual capture. The hardware supports a massive maximum effective pixel matrix of 4000(H) by 3000(V). The USB video camera provides continuous 4K video broadcasting at 30 frames per second, and an additional 1080P video mode at 60 frames per second. The physical pixel architecture of the sensor measures exactly 1.4 μm by 1.4 μm, preserving precise visual details. The camera processes optical input natively in standard YUY2 and MJPEG formats. The hardware operates with a wide dynamic range measuring 70db.

To maintain image clarity, the 4K video camera uses a 6P glass composition lens. This optical configuration is paired with an exceptionally large F1.7 aperture, enabling the web camera to capture precise visual details even in poor indoor lighting conditions. The hardware includes a PDAF (Phase Detection Auto Focus) module that controls the focusing function. The PDAF system allows the desktop camera to focus quickly on moving subjects without contrast-based delays. The lens provides a specific angular field of view of 77 degrees ±1 degree.

The device incorporates dual touch controls for hardware-level image adjustments. A left touch button regulates the image brightness in a continuous loop. A right touch button manages the camera's sequential zoom capabilities. Each touch action activates a blue LED indicator to confirm user input. For audio recording, the computer camera is equipped with 2 channel stereo noise-canceling microphones. A custom 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 to the host computer. The streaming webcam is designed to operate on a DC 5V power supply, drawing a remarkably low maximum working current of just 190mA. A central indicator light signals when the image output is actively transmitting.

The hardware is broadly compatible with multiple operating systems, providing driver-free support for 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 strictly defined 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.
