it works.

1. The first function of the electronic eye for calculating the traffic flow and speed is to calculate the traffic flow. Whenever a car passes a road section, the electronic eye will flash. In fact, this is not a violation, but the electronic eye is recording the traffic flow. Electronic eyes can not only count, but also detect the speed of cars. According to the distance between two photos in unit time, the electronic eye can accurately calculate the running speed of the car. That's why you will get a ticket from the traffic police within a few hours after speeding.

2. 2. Record vehicle violations. The second function of the electronic eye is to record vehicle violations. Such as illegal lane change, reverse driving, compaction line and other illegal behaviors, will be recorded in the database by electronic eyes, and then you will receive text messages the next day. One of the most common examples of electronic eyes recording violations is running a red light. When the car is judged to have run a red light, the electronic eye will take three photos in a row. The first picture shows the front wheel running over the stop line. The second picture shows the whole vehicle passing through the stop line, and the third picture shows the rear wheel passing over the stop line. Only when there are three photos at the same time can the traffic police judge it as running a red light.

3. It is also very important to record the license plate and vehicle information. You can often see some hit-and-run events. Without the capture of electronic eyes, it is difficult to determine the identity and trend of offenders. The electronic eye can not only clearly record the license plate, but also record the appearance of the car and the information of the suspect. Therefore, the electronic eye has an indelible contribution to traffic law enforcement and solving crimes.
