Dang, I'm actually trying to disprove my friend's theory.
What mechanism does you work use for its gate?
Is it really a metal detector underneath?
Admitted I know very little about streetlights so I imagine that they use a variety of sensors, the question is if this one is being by them in any cases.
Do you know if the sensor you have at your work (I'm guessing a commercial version) is similar enough (or the same as) to a public street sensor?
P.S. I know that there used to be light sensors on the top of specific streets for Emergency vehicles and that these have been replaced in some states by a UV sensor that Emergency vehicles lights trigger; But these are specific to certain routes and usually on busier roads.
