There are cameras in front of and behind each road, and every car has to take pictures after the fight. Is it illegal to take pictures? How long will it take to find out?

This is generally ok. Belonging to traffic monitoring and traffic conditions. It usually takes 3 ~ 7 days to discover the violation of motor vehicles, and it will not exceed 13 working days at the latest. For illegal activities with uncertain vehicles, it is best to log on to the website of the Transportation Bureau where the motor vehicle is registered. You can also search for "vehicle violation" on Baidu (or directly search for the location of vehicle violation XX) and enter the inquiry system (that is, the local public security traffic police network) by region. Generally, you need to enter the license plate number and vehicle identification number (usually the frame number).
