Can Traffic Violation Cameras See People Inside the Car?
2 Answers
Traffic violation cameras can capture people sitting in the rear seats of the vehicle. Here is some information about traffic violation monitoring: 1. Definition: Violation photography refers to the process where vehicles breaking traffic laws are recorded by camera equipment. 2. Principle: Electronic eyes use induction loops to detect pressure from vehicles on the road surface. Sensors collect these signals and send them to the central processor, where they are temporarily stored in registers (this data remains valid for one red light cycle). 3. Post-processing: After images are downloaded and transmitted to the command center, they undergo registration, numbering, and announcement procedures before being transferred to the central computer database for access by various authorities.
I work in traffic monitoring equipment maintenance, specializing in dealing with these cameras. The electronic eyes we commonly refer to for capturing violations actually have very short focal lengths, primarily focused on the license plate area. Unless it's a high-definition probe specifically designed to check seat belts, it can only capture a rough outline within five meters. At night, cameras also have to deal with strong reflections, with the focus entirely on the reflective film of the license plate. Last month, there was a case where the front windshield had dark tinting, making it impossible to distinguish whether the driver was male or female, but the violation was still penalized. The legal basis for enforcement is the vehicle information corresponding to the license plate, not facial recognition.
