Route 17, NJ, county police using RDD?

hey guys, these county cops are everywhere on Route 17, NJ, mostly towards the Lyndhurst side and they are pulling people over constantly.

i see they pull over trucks a lot, even while truck drivers there are pretty good at following the speed limit. today on one of the county cop cars, i saw a boxy unit below the rearview mirror, fixed. is that a radar detector detector, and you think they have Spectre units (which only the bel Sti is immune)

thinkin they all have RDD b/c a lot of trucks get pulled over here.

could be a camera...but yea seems like a spectre

i dont think they have spectre units if soo nj you can have a radardetector...you could have been looking at a the spycam in the window witch is almost the same size as the
spectre unit idk thanks for the info

Camera
Bergen County Sheriff are cameras below RVM no spectras
