We have a web cam application where images are made from 2 cameras once per minute and stored for 24 hours. Other parts of the application can pick a particular image or play an accelerated view of them for trouble shooting. The application relates to monitoring a physical property in the ore concentrating operation which runs 24/7. I regard it as a large and complex PLC well suited to monitoring other processes.
This is a re-write of an earlier application for the same purpose. The cameras we use are Stardot Technologies win cam. http://www.stardot-tech.com/ Initially I spent a lot of effort to manage the cameras within the LV code, storing the images in fixed positions inside a large file. Now I take a more relaxed wiew and let the two cameras store their images in folders on disk and pick them off with the jpeg read function. There were some initial problems with "running out of resources" in the wincam software, but the very helpful tech support suggested that it was graphical resources that were the culprit and running it from the taskbar would avoid this. It's been running storing 2 images a minute for the last few days quite happily.
