I may be new to this board but I’m not new to the idea of finding advice in a forum so I know that searching posts and archives can be more lucrative than posting right off the bat. I also know that searching for a general term like “ring” is only going to produce hundreds of links that have nothing to do with what I’m looking for; but, I searched anyway and the one post that I saw that had a title that specifically had to do with my question didn’t have any responses. So, when I did a search of the terms “scan lines” and “surveillance camera” I turned up far more specific results. Thankfully I posted my question and got an answer. As far as I’m concerned, I did the sensible thing. Having done the sensible thing, I’m justified in being frustrated with the responses.
