IANAL but the main difference between surveillance video and his supposed demonstration here is that he is publishing them for public viewing.

I expect that would require a release form of some kind to be signed as as such is violating some laws.

The act of videoing itself is probably not against the law, but doing it without the express permission of the subjects with the view of publishing it later, is.
