Why are tech specs relevant here? The problem with Flock is that once the data is collected, and once it's made accessible to law enforcement without any legal review, it's going to be used for solving heinous crimes, for keeping tabs on a vocal critic of the police commissioner, and for checking what the officer's ex-wife is up to.
If the cameras were installed and operated by the DHS or by the local PD, would that make you feel better? The data should not exist, or if it must, it shouldn't be accessible without court approval. The model you're proposing doesn't ensure that; in fact, it moves it closer to the parties most likely to misuse it.
