How many seconds after the red light does the camera start taking photos?

Photos are taken immediately. Running a red light triggers the camera when the red light is on. The induction lines sense the pressure from vehicles on the road, and the sensors transmit the signal to the central processor, which temporarily stores it in the register. If two signals are successfully sent the moment the red light turns on, it is considered running a red light. The working principle involves taking one photo after crossing the line, another after passing through the red light, and a final one upon reaching the opposite side of the intersection. Additional Information: Note 1: The camera activates the red-light running capture system immediately when the red light turns on; there is no 3-second delay. Additionally, electronic monitoring devices for red-light running currently use two methods: digital cameras and digital camcorders. Regardless of the method, they focus on and capture a specific area around the stop line. Note 2: When the red light is on, if the front wheels of the car cross the line but the rear wheels remain within the line, only one signal is generated, making it unlikely to be captured. However, if the front wheels cross the line and the car reverses back within the line to avoid being captured, the camera may sense this and send another signal. Two signals will then be judged as running a red light.
