Although better than nothing, I can assure you that security cams are no guarantee a perp even gets identified much less caught.
Anybody that believes that has a false sense of security.
Beats nothing, but I heartily agree.
That said, my former town did a small pile of Flock cameras on all the major roads in and out several years ago. Like 16 or 18 cameras, maybe more now.
There are more felons with outstanding warrants driving around in cars registered to them, than you might expect. And the PD hauled them to the county jail.
