4.5 Analytics Configuration
This device supports certain smart functions, such as object removal, line crossing detection, region intrusion, etc. These events can be triggered as
alarm events.
Note: For more accuracy, here are some recommendations for installation.
 Cameras should be installed on stable surfaces, as vibrations can affect the accuracy of detection.
 Avoid pointing the camera at reflective surfaces.
 Avoid places that are narrow or have too much shadowing.
 Avoid scenarios where the object’s color is similar to the background color.
 At any time of day or night, make sure the image of the camera is clear and with adequate and even light, avoiding overexposure or too much
darkness on both sides.
4.5.1 Object Removal
The alarm will be triggered when objects are removed from or left at the pre-defined area.
To set object removal:
Go to the AnalyticsObject Removal interface shown below.
1. Enable object removal detection and then select the detection type.
Enable Left Detection: Alarms will be triggered if there are items left in the pre-defined area.
Enable Item Missing Detection: Alarms will be triggered if there are items missing in the pre-defined alarm area.
1. Set the alarm holding time and alarm trigger options. The setup steps are the same as motion detection.
2. Click “Save” button to save the settings.
3. Set the alarm area of the object removal detection. Click the “Area” tab to go to the interface shown below.
4. Set the alarm area number and then enter the desired alarm area name. Up to 4 alarm areas can be added. Click the “Draw Area” button and
then click around the area where you want to set as the alarm area in the image (the alarm area should be a closed area). Click the “Stop
Draw” button to stop drawing. Click the “Clear” button to delete the alarm area. Click the “Save” button to save the settings.
5. Set the schedule of the object removal detection in the Schedule tab. The setup steps of the schedule are the same as motion detection
schedule setup.

※ Configuration requirements of camera and surrounding area
1. The range of the detection object should occupy from 1 50 to 1 3 of the entire image.
2. The detection time of objects in the camera should be from 3 to 5 seconds.
3. The defined area cannot be covered frequently and continuously (like people and traffic flow).
4. It is necessary for object removal detection that the drawn frame must be very close to the margin of the object in enhancing the sensitivity
and accuracy of the detection.
5. Object removal detection cannot determine the objects’ ownership. For instance, there is an unattended package in the station. Object
removal detection can detect the package itself but it cannot determine to whom it belongs to.
6. Try not to enable object removal detection when light changes greatly in the scene.
7. Try not to enable object removal detection if there are complex and dynamic environments in the scene.
8. Adequate light and clear scenery are very important to object removal detection.
4.5.2 Abnormality
This function can detect changes in the surveillance environment affected by the external factors.
Go to the AnalyticsAbnormality interface shown below.
1. Enable the applicable detection that’s desired.
Scene Change Detection: Alarms will be triggered if the scene of the video has changed.
Video Blur Detection: Alarms will be triggered if the video becomes blurry.
Obscuring Detection: Alarms will be triggered if the video becomes obscured.
2. Set the alarm holding time and alarm trigger options. The setup steps are the same as motion detection.
3. Click “Save” button to save the settings.
4. Set the sensitivity of the exception detection. Click the “Sensitivity” tab to go to the interface shown below.
Drag the slider to set the sensitivity value or directly enter the sensitivity value in the textbox. Click “Save” to save the settings.
The sensitivity value of Scene Change Detection: The higher the value is, the more sensitive the system responds to the amplitude of the scene change.
The sensitivity value of Video Blur Detection: The higher the value is, the more sensitive the system responds to the blurriness of the image.
The sensitivity value of Obscuring Detection: The higher the value is, the more sensitive the system responds to the obscuring of the image.

4.5.3 Line Crossing
Line Crossing: Alarms will be triggered if someone or something crosses the pre-defined alarm lines.
Go to AnalyticsLine Crossing shown below.
1. Enable the alarm and set the alarm holding time.
2. Set alarm trigger options. The setup steps are the same as motion detection.
3. Click the “Save” button to save the settings.
4. Set area and sensitivity of the line crossing alarm. Click the “Area and Sensitivity” tab to go to the interface shown below.
Set the line number and direction. Up to 4 lines can be added. Multiple lines cannot be added simultaneously.
Direction ： A<->B, A->B and A<-B optional. This indicates the direction of the intruder who crosses over the alarm line that would trigger the alarm.
A<->B: The alarm will be triggered when the intruder crosses over the alarm line from B to A or from A to B.
A->B: The alarm will be triggered when the intruder crosses over the alarm line from A to B.
A<-B: The alarm will be triggered when the intruder crosses over the alarm line from B to A.
Click the “Draw” button and then drag the mouse to draw a line in the image. Click the “Stop” button to stop drawing. Click the “Clear” button to delete
the lines. Click the “Save” button to save the settings.
