What many don't realize is that a "porn shoot" doesn't film just the handful of scenes for one dvd or website. A well-run production company will bring in multiple teams to film perhaps dozens of sequences in a day. One truth about porn is that, like sitcoms, they do not require large sets. So it isn't difficult to squeeze multiple teams into a house. But the upside for neighbors is that those smaller sets don't need the generators and massive lighting rigs used to illuminate wide shots.

That's traditional porn. The other side are the smaller websites, often dedicated to a single actress. They want a site they can film very quietly over a couple days, usually a weekend. This is one camera, one or two lights and never more than a handful of people. They can come and go without even a van, without anyone noticing anything. Some call this "amateur", but I think that term doesn't do these productions justice.
