“Most every stoplight has a camera pointed into the windshield.”
Those cameras are still-shot cameras rigged to sensors and strobes so that they only take a photo when a vehicle transgresses the intersection against a red light. Typically, at least two cameras capture single frames to get vehicle license plate and driver’s face.
Here’s what’s important, though, in terms of everyone’s privacy: Red light cameras are not always-on video cameras; that type of camera would yield image frames at too low of a resolution to be useful. Even full HD video has difficulty clearly capturing a moving object the size of your head from a distance of fifty feet. The combination of video frame rate, and motion blur (stationary camera v. moving subject) — I see full HD home security video from time-to-time, and if the camera is mounted on the front of a house, and the subject is at the curb, even just 30 feet away their facial features are muddied unless they actually STOP still for a moment facing the camera. That is absolutely never going to happen if you’re blowing through an intersection at 35mph.
IOW, unless you are planning to run red lights as an avocation, don’t even bat an eyelash at the presence of those red light cameras.
Not in Indianapolis.
We have NO red light ticket stuff
Plus the cameras do NOT aim at plates!
Check out this intersection in StreetView. all four cameras on the light poles are looking across the intersection into the windshield...
