The rules regarding audio recording are different from video. This is why many security cameras do not actually record audio.

I think the laws are different primarily due to the different pace of audio vs. video recording technology. Audio recording of phone calls etc. has been feasible for a long time so laws were written about that. Ubiquitous video recording has really only become a thing in the past 2 decades or so.

Absolutely. I feel like the pace of adoption has been mostly driven by per-bit storage costs falling (and high efficiency codecs).

Above all else, people will do useful things with computers once the price to do so matches the utility. And we're far on the other side of that with cameras.

I can't wait to see what the next decade+ does to all the Facebook-esque camera startups. It's going to be hard to monetize your customer's video feeds once regulation clamps down.
