Hello, I live in Los Angeles and I was driving on the 134 freeway east, a few miles before catching the 210 east. I was on my way from the San Fernando Valley to Arcadia. On the 134, I noticed a sign that said "radar used to enforce the speed limit". I few miles after the sign, I saw a camera on the freeway, it was on top of one of the road signs and seemed about 2 feet in length, with a diameter of maybe 8 inches or so. I was going about 10 miles over the speed limit and worry it might have been some type of camera that uses radar to measure peoples speed. Do the cameras look like the one I described, or am I being paranoid.
