USB 2.0 Web Camera 1/2.5 Inch Sensor PDAF 4K 30FPS Desktop Cam 874L

This USB 2.0 web camera is built with an advanced 1/2.5 inch optical image sensor, ensuring high light sensitivity for desktop recording. It supports a maximum effective pixel matrix of 4000(H) by 3000(V). The desktop cam delivers 4K video resolution at 30 frames per second and an alternative 1080P output at 60 frames per second. The internal pixel structure is strictly measured at 1.4 μm by 1.4 μm. Video streams are encoded and processed in standard YUY2 and MJPEG formats. The optical hardware is tested to support a broad dynamic range of 70db.

The optical path features a 6-element (6P) glass lens assembly. The lens incorporates an exceptionally large F1.7 aperture, allowing the PC web camera to capture precise details even in low-light environments. The field of view is calibrated to 77 degrees with a tolerance of ±1 degree. For focusing, the camera uses Phase Detection Auto Focus (PDAF) technology. This PDAF integration ensures the computer camera calculates spatial depth instantly, avoiding the mechanical hunting effects seen in traditional webcams.

A unique hardware feature of this streaming camera is its dual-side touch interface. Tapping the left touch sensor cycles through brightness levels, while the right touch sensor activates a hardware-level zoom function. A blue LED flashes to confirm touch operations. Audio communication on this desktop video camera relies on 2 channel stereo noise-canceling microphones. To ensure user privacy, a magnetic privacy cover securely attaches to the front of the lens.

The hardware links to the host PC via a standard USB 2.0 communication protocol. This ensures the USB web camera maintains stable bandwidth for 4K video transmission. The device operates on a standard DC 5V voltage and requires a highly efficient maximum working current of just 190mA. A central indicator light illuminates to signify when the camera is actively outputting video.

The structural dimensions of the 874L camera body are 74.9 millimeters wide and 46 millimeters high. The chassis includes a foldable base for monitor mounting. System compatibility includes driver-free plug-and-play support for Windows 7, Windows 8, Windows 10, Windows 11, Linux, Android, Ubuntu, and macOS. The PC video camera operates safely within ambient temperatures from 0 to 60 degrees Celsius, with storage specifications ranging between -30 and 85 degrees Celsius.
