There is one independent national study ( https://www.flocksafety.com/blog/independent-study-vehicle-t... ) which indicates vehicle thefts fell 11% following a flock installation.

However, the vast majority of vehicle thefts self-resolve ( 85% of passenger vehicle thefts are recovered, a third within one day ). Flock's apparent impact was that vehicles came back on average 1/4 day sooner; it did not appear to impact the rate at which they were recovered, so your instinct would be incorrect.

Additionally, vehicle theft has been steadily decreasing year-over-year since COVID, and it's possible/likely that the effects seen in the study were continuations of that trend rather than anything attributable to flock. The paper even says as much -- that the effect began in the months preceding flock installation.

Intuitively, you'd think that flock cameras would help a lot. I would think so too! But at least in my small-to-mid-sized city, they don't noticeably help at all with any kind of crime.
