Ring doorbells now give their footage to Flock, which can give/sell it to anyone. No warrant necessary. Not exactly what you're asking about, but along the same lines.

And police departments have absolutely bought that information, especially given their notoriously inflated budgets (at least in many cities).

Tbf, it would be pretty strange if law enforcement needed a warrant for flock camera footage, considering they're just freely accessible on the fucking internet /s
