How many seconds after the red light turns on does the electronic police camera system start taking photos?

[HeidiRose]

When the red light turns on, the electronic police camera system software is already in operation; when the traffic light turns on, the camera system software shuts down 2 seconds in advance; when the yellow light turns on, the camera system software delays operation by 2 seconds. This method helps reduce the probability of the camera system mistakenly capturing vehicles running red lights. Under the following circumstances, you can apply to the traffic police to cancel the penalty for running a red light: If you run a red light to give way to emergency vehicles such as ambulances, fire trucks, patrol cars, road rescue vehicles, or special vehicles, and if the vehicle owner has a dashcam, the recorded video can be used as evidence to apply to the traffic management department for penalty cancellation. If you run a red light under the guidance of traffic police, in many cases, if there are traffic police directing vehicle movement on-site, you should follow their instructions. If you are captured running a red light under such circumstances, you can apply for cancellation.
