Will Traffic Violation Cameras Flash at Night?

It depends on the type of electronic monitoring device—some will flash, while others won't. Violation Capture: Electronic monitoring devices use induction loops to detect the pressure from vehicles on the road. The signals are collected by sensors and sent to the central processing unit, temporarily stored in registers (this data remains valid for the duration of one red light cycle). The license plate recognition rate is over 95% during the day and over 90% at night. The vehicle capture rate is 100% (excluding two-wheeled motorcycles, etc.). The recognition time is approximately one second. Applicable vehicle speeds range from 5 to 180 km/h. Electronic Monitoring: "Electronic eyes," also known as "electronic police," are the colloquial term for the "Intelligent Traffic Violation Monitoring and Capture Management System." Developed and successfully implemented in Shenzhen in 1997, they have since been gradually promoted for use nationwide. Electronic eyes utilize various technologies such as vehicle detection, photoelectric imaging, automatic control, network communication, and computer processing to monitor traffic violations around the clock. They capture violations such as running red lights, driving in the wrong direction, speeding, crossing lines, and illegal parking, recording image and text data of the violations for subsequent processing based on the captured information.
As someone who has long studied traffic monitoring equipment, I've noticed whether nighttime violation cameras flash depends on the device type. Traditional cameras rely on flash fill lights, especially on poorly lit road sections, where the sudden bright light can indeed be as noticeable as a camera flash. However, in recent years many cities have switched to infrared devices that silently capture images in darkness without any interference to drivers' vision. Additionally, some road sections are equipped with constant fill lights that maintain dim illumination throughout the night without sudden flashes. It's advisable to reduce speed when passing monitored sections at night - after all, speeding will be captured whether there's flashing or not.
