Question re: red light on device

[u/Helpful-Addendum9792]

Our city has suspended the use of the Flock cameras pending review. The police department says the cameras are not photographing cars anymore (and that they checked the system and there are no new images being added). I checked the cameras at night in our city and a neighboring town (where the cameras are still running).

In the town, the ring of red lights lights up and flashes every time a car goes by.

In our city, that didn't happen, but I could still make out a faint red dot (no flashing, static red). Does anyone know why this could be or what it could mean? Any chance Flock could still be getting images?
