To prevent crime:
Most video surveillance is used to prevent crime. The fact is, people get nervous when they see surveillance cameras, and more often than most, even a mannequin camera is enough to deter potential criticism of vandalism or on-the-spot robbery.
For traffic monitoring:
Video surveillance is designed to monitor traffic, monitor traffic jams, potential collisions, and traffic violations. Traffic accidents cause a large number of injuries and deaths worldwide. When motorists and pedestrians know activity is being monitored, they are less likely to inadvertently break the rules.
Some CCTV cameras can act as traffic control cameras to detect speed violations, detect license plates, and enforce traffic rules. A lot depends on where the cameras are placed, how well they work, and how effective the people watching the camera are.
