Review on Longruner Day & Night Vision Camera For Raspberry Pi: 1080P HD Video With 5MP OV5647 Sensor - Perfect For RPi 4, 3B+, 2B, Zero W & More! by Jevon Sterling

Running Octoprint from a Raspberry Pi Zero 2W for my first time (new to Raspberry in general.) One thing I wanted to mention is that I had everything set up before installing this camera and mount and the quality was grainy at best. I tried updating the code directly on my Pi within the config.txt (think that's the name) to bump up the resolution and FPS to 30, but the image was still grainy. I believed you had to leave the USB line as-is but uncomment that, but perhaps what I read was wrong.Well, I had to rebuild my OS because I made some dumb mistakes with something else. Reinstalled the Raspberry PI OS and Octoprint with this camera attached for the first time, and the camera is SO MUCH BETTER. I'm not sure what changed with the config file versus my manually adding to the code, but something is VERY different. So if you're experiencing graininess AFTER having already installed Raspberry and Octoprint, there is a setting somewhere which is impacting the overall quality.
