Some of these aren't cameras at all. Though they look like cameras, alot of these are motion detectors (laymans term) to tell the stop light system which direction of travel currently has more traffic flow and that system is what makes the decision of which lane gets the green light. These systems also except a signal from a piece of equipment on most fire trucks and ambulances called opticom emitters. This switches the red light to an emergency function that stops traffic from all opposing directions of travel from the fire engine so that they may respond to their emergency more safely.Keith B wrote:They are what are called 'Traffic Cams' and not all of them are constantly recording to video. However, they can be accessed remotely by approved agencies at a moments notice if they need to view something or start recording.sjfcontrol wrote:Has anybody else noticed that every intersection with a traffic light has cameras pointing in all traffic directions. Where does all that video go?
I installed several of these systems. Long winded explanation, I know...
