It's good. Jiaonan Wawu intersection monitoring is located in Qingdao, Shandong Province, and the monitoring is very accurate. The purpose of this monitoring record is mainly to record the traffic volume, the type of each car and even the situation inside the car. When necessary, the police uncle can retrieve these videos and photos to hunt down criminals and investigate cases. The other is illegal evidence collection. The first recording is to record the initial information, but it is illegal to flash several times in a row.
