This is kind of a misconception about the technology; there is not really much distinction between these things. Firstly, they are cameras which have no means of differentiating between a license plate or a dog or a tree. In addition to that, they are (presumably linux) computers that have software to find license plates in the images the cameras take, both of which (license plates and images) are stored on Flock's servers. That's how the "recording license plates on public roads" bit works.

The point is that the images can still be ran through creepy software written by creepy people to find children to get to "logging people in public places". And let's say, to put it mildly, it does not fill one with confidence to research the security in practice of Flock's image data.
