Can illegal cameras capture speeding violations?

Illegal cameras can capture speeding violations. The following is an introduction to the principles of speed detection systems: 1. Speed measurement methods: Speed measurement is divided into fixed-point speed measurement and interval speed measurement. Fixed-point speed measurement measures the instantaneous speed of a vehicle, which must not exceed the speed limit of the road section. 2. Speed measurement distance: Interval speed measurement calculates the average speed by dividing the distance traveled by the time taken. If the average speed is higher than the speed limit, it indicates speeding. 3. Speed capture rate: Current speeding violation capture systems can achieve a vehicle capture rate of 100%, with a recognition time of about 1 second. The daytime vehicle recognition rate is over 95%, and the nighttime recognition rate is over 90%. The applicable speed range is 5-180 km/h.
Of course, traffic cameras are designed to catch speeding, and I've seen quite a few of these devices over my years of driving. The common fixed poles on highways use radar or laser to measure vehicle speed, automatically taking photos if the speed limit is exceeded. These photos include the license plate number, time, and speed data, which traffic police use to issue tickets. It's not just urban roads that have these devices; rural roads also have mobile police cars stationed with portable speed measurement and photo equipment. Actually, many people don't know that camera angles and weather can affect the clarity of the photos, but overall, they're quite accurate. So, when driving, I always recommend keeping an eye out for roadside signs, especially slowing down when passing speed cameras. Developing this habit can save you a lot of trouble and fines.
The working principle of speed cameras is quite straightforward. They use radar waves or laser beams to detect vehicle speed, paired with high-speed shutter cameras to capture images. As your car moves, the device emits signals to calculate the time difference and determine if you're speeding, then snaps a photo of your license plate. This method doesn't just catch speed limit violations but also includes infractions like running red lights, with the data directly stored in the system for traffic police review. Interestingly, modern devices can even recognize faces or in-car behavior, but the focus is on preventing false captures. There are various types of equipment, such as fixed units mounted on poles or mobile ones on police car roofs, and their use must comply with local regulations to be effective. In short, they are ingeniously designed with the sole purpose of maintaining road safety.
