4K Streaming PC Camera F1.7 Aperture PDAF Touch Control Webcam 874L

This 4K streaming PC camera is powered by an advanced 1/2.5 inch 12MP optical image sensor. The device supports a maximum effective pixel resolution of 4000(H) x 3000(V). It provides a continuous 4K video output at a stable 30 frames per second, alongside an alternative 1080P output option at 60 frames per second. Featuring a physical pixel dimension of 1.4μm by 1.4μm, the sensor guarantees high image fidelity for broadcasting. Video data is processed natively in standard MJPEG and YUY2 formats, and the optical sensor maintains a wide dynamic range of 70db.

The optical system of this streaming camera utilizes a 6P glass lens composition. This dedicated lens assembly features an F1.7 large aperture, allowing the PC cam to capture maximum light in challenging desktop setups. The computer camera projects a specific angular field of view calibrated to 77 degrees ±1 degree. The device utilizes Phase Detection Auto Focus (PDAF) technology, ensuring the camera focuses almost instantly on moving subjects without the delay of traditional contrast-based 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 continuous loop. A right-side touch key enables a sequential hardware zoom function. Both touch keys trigger a blue indicator light upon successful actuation. Voice communication on this PC webcam is captured by integrated 2 channel stereo noise-canceling microphones. A magnetic privacy cover is also included to physically block the lens and ensure security when not broadcasting.

Data is transferred to the host computer through a standard USB 2.0 interface. This connection standard ensures the 4K web camera can transmit high-resolution video streams reliably. Operating on a 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 device.

The hardware enclosure is designed to occupy minimal space, with the main body measuring 74.9mm in width and 46mm in height. This USB web 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.
