Reading through a couple of the descriptions it looks like they have a state-wide database for searching face images against FL driver's licence photos. Since all the departments are signed onto the system, they all get the symbol but there may be other reasons/more invasive systems mixed in with the clutter so take that for what it's worth.

In Monroe county, FL we voted out a host of surveillance tech like traffic cameras etc. I was actually surprised to see that the sheriffs office signed onto the Ring data sharing as surveillance tech has been thoroughly rejected by our community, and we are small enough and close knit enough down here, that organized movements regularly vote people out that cross too far over the line.

That being said, the police force has a pretty stellar reputation of not looking for trouble and bad cops are usually shown the door pretty quickly. The rest of FL though is a mess, traffic light cameras everywhere, licence plate scanners, stingray. You name it they are decked out with it.
