The scarier thought to me is that this many cameras installed in houses, businesses, bedrooms, etc. are being commandeered. That's a huge problem for privacy, let alone being used as botnets on the side.
You are correct. I know there are sites out there that even aggregate camera feeds, although the more ethical ones remove any feeds where there may be privacy concerns.
Frankly, I would NEVER install such a device in my house. The engineering on many is (almost?) criminally flawed.
