Intelligent Video Analytics currently has many international names, such as VCA (video Content analysis), VA (video analytics), IVA (Intelligent video), and so on. This is a branch of computer image Vision technology application in security field, it is a kind of intelligent monitoring technology based on video analysis.
This intelligent video analysis is mainly about the application of behavioral analysis. All video analysis is based on the effective identification of the target in the video, and unlike traditional motion detection (Vmd-video motion Detection) technology, intelligent video analysis first separates the background and target in the scene, identifies the real target, and removes background interference (such as leaf jitter, Surface waves, light changes), and then analyze and trace the target behavior in the camera scene, obtain the behavior properties of these targets, and then compare with the user pre-set rules to determine whether to send an alarm.
There are several types of behavioral analysis:
Algorithm name |
Function |
Trip Line Detection |
Detects if a target crosses a virtual detection line and supports unidirectional and bidirectional traversal detection |
Connecting the trip line detection |
Detects if a target connection crosses multiple detection lines |
Intrusion detection (Entry detection) |
Detects if a target is entering the region through the edges of the specified area |
Leave detection |
Detects if a target is out of the region by the edge of the specified area |
Residue detection (abandonment detection) |
Detects if an object has left the specified detection area |
Removal detection |
Detects if an object is removed from the specified detection area |
Wandering Detection |
Detects if a target is hovering within the specified area for longer than the set time |
Run detection |
Detects if the target moves too fast |
Fall Detection |
Detects if the target falls in the specified area |
Violent incident detection |
Detect the presence of violence in the scene |
Crowd aggregation detection |
Detects if a crowd gathers in the scene |
Retrograde detection |
Detects if a target is retrograde in the specified area |
Pyrotechnic inspection |
Detects fireworks in a specified area |

Statistics in the scene of people, traffic |
