Review on ALPCAM 4K USB Camera Ultra HD 2160P Webcam with 5X Optical Manual Wide Angle Lens, 2.8-12mm Varifocal Lens, Sony IMX317 Sensor, USB Zoom Video Conference Camera for Mac, Windows, Linux, Raspberry Pi by Joz Lowe

First impressions: This is an amazing looking camera. Looks like cool spy gear. Appearance, of course, does not make a high-quality picture. I plugged it into my Windows 10 PC and it popped up right away. Open the camera app and the video was right there. True plug and play. Works great right out of the box very easy. The picture is very good, very good. I personally don't know if it's 4K quality, but it's close and more of an opinion. Of course I can't complain about the picture. Anyway, I don't know how to prove it's 4K. But I'm very happy with the video he's putting out. This is certainly not autofocus, but it's very easy to focus on, the ring rotates smoothly. You can also adjust the brightness. The camera is also more suitable for close range than a far away camera. It really looks like it has a tripod thread mount. Very practical for many uses and applications. I'm thinking of using this to monitor either my laser or one of the 3D printers. Follow him from another room. Excellent camera, good price too, happy to recommend.
