TL DR: Depstech does make exaggerated claims about the DW49 specifications, but the difference from reality is less than some other “4K” cameras I’ve seen. I will try to find out what’s inside the webcam by disassembling it and making some measurements, but I’ll leave the more subjective image quality and “is it good?” opinions to the many reviews online. Since other reviews confirmed that this webcam is at least capable of a reasonable image, and $30 wouldn’t be overpriced even if the specifications weren’t accurate, I decided to buy one to see what’s inside.

Despite the abundance of online reviews for this camera, I haven’t found any that verified the accuracy of the specifications claimed by Depstech. One common scam is to use a lower-resolution image sensor and then scale up the image to 4K, resulting in a video with the right number of pixels, but a blurry picture. “4K” cameras at this price point often misrepresent their capabilities.

I recently got one “used” (but seemed unused) from eBay for $30. The Depstech DW49 is a low-cost webcam that claims to record 4K 30 fps video.
