Yes i have seen this in Ramada signal as well as Airport signal.

I
think airport signal catches more vehicles. its a funny thing to note
that while you are at the airport signal if you look around you can see
surrounded by cameras everywhere.

slow down and avoid tickets 

I was just wondering about the amount of money they get from these cameras,

i dont wanna make a donation anyway....... 

YOU DONT KNOW ME, DONT EVEN TRY !!!
