I purchased this camera for machine vision development in Linux. It worked as soon as I plugged it in with V4L2 in Ubuntu 14.04. The 180 fisheye lens is great and has little chromatic aberration and distortion. It's not perfect, but it's far superior than I expected it would be for the price. The resolution you select determines how much of the frame is visible. i.e. the only way to see the entire circular fisheye image is to run in 1080p30, while the 720p60 option will window the viewport instead of resizing the image. This keeps the lag down, which I do appreciate.
The framerates are also great. At first, I was concerned that I was not getting effective 1080p30 and 720p60, but in the camera configuration you can disable backlight compensation to always get full framerates. Provided you can provide enough illumination, it works very well. The image quality is not the highest, but this at this price point, it can't be beat.
Finally, before I even received it, Lydia from their support staff reached out to check to see if I had any troubles. Whoa. I'm very pleased with the service and the camera. I plan on purchasing some more ELP cams for my future projects.
