12MP USB 2.0 Camera F1.7 Aperture Touch Zoom PDAF 4K Web Camera 874L

Engineered for superior desktop broadcasting, this 12MP USB 2.0 camera utilizes an advanced 1/2.5 inch optical image sensor. The hardware provides an ultra-high maximum effective pixel resolution of 4000(H) x 3000(V). It offers a continuous 4K video output at 30 frames per second, and a fluid 1080P output option at 60 frames per second. Featuring a physical pixel dimension of 1.4μm by 1.4μm, the optical sensor guarantees high image fidelity. Video data is processed and transmitted natively in standard MJPEG and YUY2 formats , and the hardware maintains a tested dynamic range of 70db.

The optical path of this 4K web camera utilizes a 6-element (6P) glass lens composition. This dedicated lens assembly features a massive F1.7 aperture, allowing the computer camera to capture maximum light and significantly reduce digital noise in dark environments. The device projects a specific angular field of view calibrated to 77 degrees ±1 degree. The camera utilizes Phase Detection Auto Focus (PDAF) technology, ensuring the lens focuses almost instantly on users without the mechanical delay inherent to older autofocus mechanisms.

Interactive control is a core functional feature of this desktop camera. A left-side touch key allows the user to adjust image brightness in a loop. A right-side touch key enables a sequential hardware zoom function. Both touch keys trigger a blue LED indicator light upon actuation. Voice communication on this streaming camera is captured by integrated 2 channel stereo noise-canceling microphones. A high-quality magnetic privacy cover is also included to physically block the lens and ensure security.

Data is transferred to the host computer through a standard USB 2.0 connection. This connection protocol ensures the PC web camera can transmit high-resolution video streams reliably. Operating on a standard DC 5V voltage, the streaming webcam requires a maximum working current of only 190mA. A central indicator light illuminates specifically when the video feed is actively transmitting image data to the host.

The hardware enclosure is designed to occupy minimal desktop space, with the main body measuring 74.9mm in width and 46mm in height. This USB video camera offers extensive plug-and-play compatibility across multiple platforms, including Windows 7, Windows 8, Windows 10, Windows 11, Linux, macOS, Android, and Ubuntu. The internal electronics are rated for a safe working temperature between 0 and 60 degrees Celsius, and the device can be stored safely in environments ranging from -30 to 85 degrees Celsius.
