Adjusting focus of Gemius QCam 6000

Published on March 23, 2024 · Reading time: 1 minute

I’ve “hacked” this little webcam to be more useful for local recording, and to improve image quality for video calls when I work from home.

OBS Studio says this is a 1080p camera with a framerate of 30 frames per second. The overall image quality is okay for this price point (€50 back in 2020), but for whatever reason I couldn’t take a crisp shot of a text, for any distance between a piece of paper and the device.

I’ve opened the camera using a plastic tool. Unfortunately, no screws were used here, and you need quite a bit of force to perform the operation.

The lens is held in place by some kind of glue, but it’s not epoxy. You can use any sharp object to scrape it off. Carefully rotate the lens and try to find the best setting for the preferred distance.

I have no pictures “before” the adjustment, but here’s the final result in the artificial lighting:

By the way, this device features a tripod mount, but I couldn’t find the thread size online, even in the user’s manual. I’ve bought a cheap 1/4-inch camera stand, and it’s possible to securely mount this webcam.
