To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Having owned the V1 Pi NoIR module, I was looking forward to the upgrade to the V2. Little did I know, when I first installed this camera on my new Pi Zero, it was completely out of focus! I scoured the Internet for solutions, only to find tales of "a batch that were made with a 1m focus distance" along with tutorials on how to "break the glue to fix the focusing issue". Luckily, a cooler head prevailed, and I inspected the round ring that came in the box - it was a focusing knob! A couple of twists later, and everything came right into view.
Excellent for its purpose. If you need a surveillance camera this is great. Works well in daylight (though colors are washed off due to the lack of IR filtering). When lit at night by standard flourescent and LEDs the colors appear suprisingly well. Combine this with a 850nm IR LED then you have excellent visibility in the dark. Works outdoors too, you only have to slightly change the focus by rotating the lens.
THE BOX ARRIVED SMASHED! Other than that, the camera is "just okay". The pics are not as focused as my older 1.3 camera but it will work for what I need it for. You need to adjust the focus with the supplied tool or the clarity is really bad. I thankfully found no glue on the lens bezel as described on many websites. I was glad that the adjustment could be made easily without pliers and it didn't mess up the bezel at all. This is a specialty camera with no IR filter so if you're looking for normal pictures will full color quality, this isn't the camera you want. Included in the box are: the camera, lens adjusting tool, 6" ribbon cable and the blue filter.
This was a first time purchase to make my own surveillance cam without Chinese malware...It doesn't have an IR filter meaning there's a purple hue to the video. I bought an ir filter ($9) to add to the lens and it fixed the color issue, but the picture quality is still that of a very old web camera. Even with resolution set as high as it can go.
Only gripe is that there seems to be some color manipulation that messes with the original sensitivity. There should, e.g., be a significant difference in sensitivity of red vs green vs blue pixels around 800nm, with that light effectively appearing orange, but there isn't, it's white. Presumably they did this to make IR images have higher contrast and look less wonky, but it takes away some utility.
I got this camera to use with Octoprint for my 3d printer. I wish I had bought the regular camera module instead as the video quality is not great and the color is WAY off. The picture is taken at 11:30 am with the lights in the room on. You can see how pink everything is.
For my needs, it does the job of letting me see if there are issues with prints, but that is about it.
