Object Identification
Object identification refers to the identification on various and objects in the monitoring menu, including people、vehicle、carton、bag and other objects. Object identification is the premise for intelligent analysis. Highly precise intelligent analysis is based on accurate identification on each object in the monitoring menu.

1、Object Track

object track is to use image identification technology and video activity analysis technology to analyze the movement direction of various objects, like people、vehicle、carton and bag in the monitoring menu and further judge their movement direction and speed. According to the data, it can automatically lead the PTZ of the camera to real-time track moving objects.

2、Crossing Identification（single line）

Draw a virtual guard line in the monitoring menu. Once in the monitoring menu some people、vehicle、carton、bag and other objects cross this guard line in a scheduled direction, it will trigger an alarm of crossing guard line. To cross guard line is divided into one-way crossing and two-way crossing：One-way crossing regulates that it will trigger an alarm to cross the guard line in a scheduled direction while two-way crossing refers that it will trigger an alarm to cross the guard line in any direction.

3、Crossing Identification（double lines）

Crossing double guard lines refers that when some people、vehicle、carton 、bag and other objects cross the first guard line，it does not trigger an alarm；To cross the second guard line within a scheduled time will trigger an alarm of crossing double guard lines.
Entry Identification
Entry identification refers that when some people、vehicle、carton 、bag and other objects in the monitoring menu enters a scheduled area from its boundary, it will trigger an entry alarm. This area is also scheduled virtual area in the menu, and may be rectangle or irregular polygon.
Leaving Identification
Leaving identification refers that when some people、vehicle、carton 、bag and other objects in the monitoring menu leave a scheduled area from its boundary, it will trigger a leaving alarm.
Leaving identification and entry identification both are to prohibit objects to enter or leave a scheduled area within certain time.

4、Appearing Identification

Appearing identification refers that when some people、vehicle、carton、bag and other objects appear in a scheduled area in the monitoring men, it will trigger appearing alarm. Appearing identification and entry identification both are the analysis identification on what happens in a scheduled area in the monitoring menu. The difference is that entry identification emphasizes that an object enters into a scheduled area from its boundary；while appearing identification emphasizes that an object suddenly appears inside a scheduled area（for example, a robber maybe digs a hole （scheduled area）from underground and comes out. Such circumstance accords with appearing identification, but not entry identification）.

5、Disappearing Identification

Disappearing identification refers that when some people、vehicle or other objects disappears out of a scheduled are，it will trigger disappearing alarm. Disappearing identification emphasizes that an object suddenly appears out of a scheduled area while leaving identification emphasizes that an object leaves the boundary of an area.

6、Stay-in identification

7、Discarding Identification

Discarding identification refers that when a monitored object discards something in a scheduled area and fails to take it away within a scheduled time，it will trigger discarding alarm. In its anti-terrorism application, when an unidentified person discards personal luggage，it will trigger discarding alarm. The operation personnel will find discarded unknown parcel at the first moment and in time go to the scene to remove suspicious object.

8、Taking-away Identification

Taking-away identification refers when something in a scheduled area is taken away , it will trigger taking-away alarm. Taking-away identification is applicable to the monitoring on precious things or specially monitored object; for example, when a famous painting in a museum is taken away, it will trigger taking-away alarm.

9、Scene Change Identification

Scene change identification refers that when a scene changes because the camera is turned toward different position or covered, intelligent video analysis system can automatically capture this activity and generate scene change alarm.

10、Detention Identification

Detention identification refers that when the detention time of an object in a scheduled area exceeds scheduled time, it will trigger detention alarm. Detention identification can be used for the monitoring on bank ATM; for example, at money drawing, it can probject someone behind the payee to detain for a long time.

11、 Object Count

Object count refers to the counting of the quantity of the objects appearing in a scheduled area（people、vehicle、carton、bag and other objects）.

12、Object Size Filter

Object size filter function refers：schedule two objects of A and B with different volumes in the monitoring menu（A>B）. The system can automatically filter the objects bigger than A or smaller than B while only analyze the objects, the volume of which is between A and B so that it can effectively reduce the error during the identification and promote accuracy.
