Does Flock have a competitor who can undercut it on price and provide entirely local data storage and management (or a zero-knowledge cloud)?

If I understand correctly, a police query to Flock makes inferences from the set of all municipality/HOA/BigBogStore flock cameras. Or at least the ginormous subset who haven't opted out of the default settings that make Flock appealing to police in the first place.

If your imagined competitor doesn't offer that feature, then how is it a competitor?

If your competitor does offer it, then why would it even matter whether ICE gets access to inferences derived from the cloud vs. some federation of local storage devices?

Any security camera product can do this, Flock is winning on having an integrated cloud solution with an all in once price that integrates with a lot of other law enforcement tools.

You can put a camera on a pole with a cell router and enable the LPR plugin in your recording software pretty darn cheap. But you probably can't do that with a single subscription apart from Flock.
