Anyone know what's on the roof of this Tahoe?

Looks kind of like one of those speed cameras that are on the highways... or an ALPR

Looks pretty similar to the unit in this article, so most likely a License Plate Reader Camera. License plate reader proves a sound investment for Olive Branch police » The Commercial Appeal

It's almost certainly a steerable camera of some type. Either speed or ALPR.

L A S E R!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


If it is an ALPR, I wonder how fast it gives a return at highway speeds.

Dang, a lot different than the LPR I have on my car. Interesting.

Yep, definitely a LPR. Remember seeing them used on TLC's "Police Women of Memphis"
