Generally, violations captured by electronic surveillance can be checked online within 3 to 7 working days. Considering that law enforcement agencies may not update the website on weekends, violations can usually be checked within 10 days after the incident. "Electronic surveillance" is also known as "electronic police" and is the common name for the "Intelligent Traffic Violation Monitoring and Recording Management System." Here is some related information about electronic surveillance: 1. Electronic surveillance uses various technologies such as vehicle detection, photoelectric imaging, automatic control, network communication, and computer systems to monitor violations such as running red lights, driving in the wrong direction, speeding, crossing lines, and illegal parking. It captures images and information of violations for subsequent processing. 2. Electronic surveillance uses induction lines to sense the pressure from vehicles on the road. The signals are collected by sensors and sent to the central processor, where they are temporarily stored in a register (this data is valid for one red light cycle). 3. If two pulse signals are generated simultaneously within the same time interval (during a red light cycle), it is considered "valid." Simply put, if a car's front wheels cross the line during a red light but the rear wheels do not, only one pulse is generated. If there are not two consecutive pulses, no photo is taken.
