How many seconds after the red light does the camera start capturing?

Photographs are taken when the red light is on. When the yellow light is on, the camera system delays for 2 seconds before activating. Drivers need to pay special attention to the changes in traffic lights. Relevant information about traffic lights is as follows: 1. Introduction: Traffic signal lights are lights that command traffic operation, usually consisting of red, green, and yellow lights. The red light indicates prohibition of passage, the green light indicates permission to pass, and the yellow light indicates a warning. 2. Control method: The most basic control method is the timed control of a single intersection. Line control and area control can also use timed control methods, also known as static line control systems and static area control systems.
I remember driving for over a decade, and based on urban traffic experience, red light cameras usually start working the moment the red light turns on, without a fixed few-second delay period. The system is designed for real-time monitoring—sensors are triggered as soon as the light turns red, and vehicles crossing the line are immediately photographed. Some friends speculate there might be a 1-2 second buffer, but that's just a rumor. I personally tried running a yellow light at an intersection, and the flash went off right after it turned red. While driving, safety comes first—stopping at red lights is key. Don’t dwell on timing. A yellow light is a warning, and red means stop. The camera system is highly sensitive with no buffer opportunity. In short, following the rules is what matters most.
