Review on 📷 Enhance Raspberry Pi Camera Performance with Arducam: Night Vision Low Light Fisheye Video Camera for Raspberry Pi 4/3/3 B/3 B+/Zero&W, with Automatic IR-Cut Switch by Rebecca Colon

Maybe received the lemon, not sure. I have many Arducam cameras. I bought a 170 degree ultra wide camera. Three corner cameras are sold under the same product ratings. The lens did not fit through the plastic stand. I wrote a question and the answer said to unscrew the lens as the seller didn't check if the stand would work. I deleted the question as another person asked the same thing. I unscrewed the lens and there were innards ready for dust to enter. I attached the stand. I tested the camera and it worked with opencv. Unfortunately, the camera does not focus. After turning the outer screw for a while, I found that it was just a spacer screw. Spirit. Then I asked another question about rotating the lens. I assumed it was the same lens rotation that the lens picks up. Nothing. The camera does an excellent job of focusing on my fingerprints. But it is not further focused. I also noticed that my instructions had handwritten marks indicating that the camera had a 140 degree field of focus, which was not the same as the 170 degree I bought. Whether it was a seller markup or a returned item. Who knows, but it doesn't work. Sorry for returning the camera.
