4K Varifocal Webcam for Flexible Streaming

The ALSEYE webcam uses a 1/2.8 CMOS IMX415 sensor to capture 3840x2160 UHD video at 30fps. Its 2.8-12mm manual varifocal lens lets you adjust zoom, focus and iris for different scenes. The camera connects via USB and works with Windows, Linux, Raspberry Pi and Mac without extra drivers. It suits creators who need optical framing control rather than fixed wide-angle views.

Check USB Power and Mounting Before Buying

Verify your device supplies enough USB current for a 4K UVC camera and that you have a free port for the three-metre cable. No tripod or bracket is included, so confirm you own a mount with a 1/4-20 UNC thread or plan to buy one separately. The plug-and-play design needs no software install, but OTG support on mobile devices should be checked against your specific hardware.

Manual Lens Control and Standard Mount Thread

The all-metal lens barrel allows precise optical zoom and focus adjustments by hand, avoiding digital crop artefacts. A built-in 1/4-20 UNC hole lets you attach the camera to standard photo tripods or brackets for stable positioning. The three-metre USB cable gives placement flexibility without signal loss. Low-light sensitivity remains strong even in dim rooms.

Questions about this item

Does the webcam come with a mounting bracket or tripod, or do I need to buy one separately?

The webcam has a 1/4-20 UNC mounting hole so you can attach it to any standard tripod or bracket; no bracket or tripod is included in the box.

The model lists a 2.8-12 mm varifocal lens — how do I decide which focal length to set?

Turn the lens barrel by hand to zoom between the 2.8 mm wide angle and the 12 mm narrow view until the framing matches your scene.

What does the 3840x2160 at 30 fps spec mean when I plug the camera into my PC?

The IMX415 sensor delivers 4K UHD video at 30 frames per second over USB with no driver installation required on Windows, Linux, Raspberry Pi or Mac.
