I agree it's not snuck up on you. It's trivial today for those tertiary video cameras to collect meta data directly (Changes) or with inference (facial recognition) to see who goes where. For you to suggest no one will watch them begs the question that the meta data isn't collected. It may not be, but it might. So a video camera that's not watched by humans 'wittingly' may still be collecting privacy decreasing data.
