Through the intelligent analysis of the video images collected by the camera, a variety of detection can be carried out: sudden intrusion detection, moving object detection, motion path detection, left object detection, motion direction detection and removed object detection, so that people or objects can be analyzed, and "crossing", "emergence", "increase" and "left" can be defined "Long stay", "gathering", "violation of access rules", "vehicle retrograde" and other alarm rules.

1、 Sudden intrusion detection

In the setting area of video image, it can detect sudden and invasive objects and give an alarm in time. It can be applied to key units such as military important places, armories, prisons, residences of national leaders and important people, gun explosion-proof and highly toxic chemicals. At present, the video mobile alarm technology often used in video surveillance system is a preliminary sudden intrusion detection technology.

2、 Moving object detection

In the area set by the video image, the dynamic tracking of moving objects can detect whether there are suspicious people entering, staying or wandering in the set area, track the detected objects and give an alarm. It can also be applied to military areas, armories, prisons, residences of national leaders and important people, airports, highways, railway stations and ports.

3、 Motion path detection

In the area set by the video image, intelligently monitor whether people, vehicles or other objects cross into a designated area along a certain direction, detect, track and alarm the target objects entering the set area in time. It can detect whether the vehicle is retrograde and whether people enter from the prohibited exit. It can be applied to vehicle retrograde, illegal U-turn, illegal left turn and illegal exit Turn right, run a red light, people are retrograde at the airport and customs entrances and exits.

4、 Legacy object detection

In the area set by the video image, detect that vehicles or other objects stop or stay for more than a certain time, and detect and alarm the objects deliberately placed in the set area, such as packages or explosives left by people. It can be used for anti-terrorism behavior detection in airports, subways and other traffic fortresses, or in public places in complex environment, and can be used in tunnels , detection of illegal parking on expressway.

5、 Motion direction detection

In the area set by the video image, the intelligent monitoring vehicle or pedestrian moves towards or away from the determined target according to multiple predefined directions. It can accurately identify and judge the movement direction of the object. It can be applied to military important places, armory, prisons, oil fields, important national offices, national leaders, important people's residences and other occasions.

6、 Removed object detection
When the target in the set monitoring area is removed, replaced or maliciously blocked, an alarm will be sent out. It can be used to protect property security. It is very suitable for places where valuables are placed, such as museums, jewelry stores, exhibitions and so on.
