The types of security cameras are roughly divided into: license plate cameras, traffic cameras, security cameras, and face recognition cameras. The following are the types, styles, classifications and application scenarios:

1. License plate camera, License plate recognition technology can extract and recognize moving license plates from complex backgrounds, and is an intelligent recognition system based on image processing, recognition, computer and other technologies , based on the characteristics of the license plate number that each car only has, the license plate number is recognized by processing the vehicle image captured by the camera. At present, the latest technical level is that the recognition rate of letters and numbers can reach 99.7%, and the recognition rate of Chinese characters can reach 99%. There are snapshot (HD) license plate cameras, recognition (HD/smart) license plate cameras, parking lot recognition cameras, parking lot license plate recognition cameras, red light capture cameras, road gate surveillance cameras, toll station cameras..

Application scenarios: parking lots and community entrances and exits, highway toll stations, highway checkpoints, etc.

2. Traffic cameras are roughly divided into two types: traffic control cameras and security surveillance cameras. The main function of the traffic control camera is to monitor the traffic flow on the road, the traffic situation at the intersection, and whether there is a traffic accident in real time. There are speed cameras, illegal parking capture cameras, traffic monitoring cameras, highway radar speed measurement capture, network intelligent traffic cameras, red light electronic police cameras, security bayonet cameras..

3. Security monitoring: The smart city surveillance camera monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and forms an independent form from camera to image display and recording Complete system. It can reflect the monitored object in real time, vividly and truly, which not only greatly extends the observation distance of the human eye, but also expands the function of the human eye. To monitor most of the actual situation at the scene and record it through the video recorder. At the same time, the alarm system equipment alarms the illegal intrusion, and the generated alarm signal is input to the alarm host, and the alarm host triggers the monitoring system to record and record.
