Application of ultra-low illumination and ultra-wide dynamic camera

The focus of low illumination and wide dynamic camera used in road monitoring is the expressway toll monitoring system, which mainly observes and records the toll situation of toll lanes, toll plazas and toll booths, observes and records the types of vehicles passing through toll lanes, the operation process of toll collectors, and the emergencies and special events in the toll collection process, and implements effective supervision. . Especially at night, toll booth staff need to see the license plate clearly. In general, after the lights are turned on, the ambient illumination on the road and the illumination of the license plate form a certain dynamic range, which is difficult for traditional cameras to "see clearly", so there is a demand for low illumination and wide dynamic cameras.

Secondly, the electronic police system, through closed-circuit television monitoring and automatic recording of red lights, can improve the command center's intuition, real-time mobilization ability and response ability to traffic accidents and accidents, and enhance the objectivity of investigating violations, and comprehensively coordinate and control the control area to improve the traffic capacity of vehicles. Because of the need to see the license plate clearly and monitor it 24 hours a day, there is a demand for low illumination and wide dynamic cameras.

In addition, there are some applications in urban commercial streets, which are used to grasp the traffic situation at some busy intersections, the running situation of vehicles around the road sections, the flow of pedestrians and the traffic security situation.
