I have a USB web cam mounted to the front end of both Y rails looking toward the center of the spoilboard, and another USB web cam mounted to the ceiling front center of the machine looking down. All three connect to a Raspberry Pi which runs a video server program. I can connect to the feed from any device with a web browser on my network. I set it up so I can keep an eye on the progress of long cuts. I could record videos of the work but that gets kind of boring to watch.
