objects that are valuable to you, (your car, for example), and once the objects are missing from the
drawn area, linked actions, (an alarm to a thief, for example), will be triggered and you will be
informed to take measures.
4.4.2.1
Basic Scene-Selecting Requirements
The target should occupy no more than 10% of the whole image.
The pixel of the target should be no less than 10×10; the pixel of abandoned object should be
no less than 15×15 (CIF image); the width and height of the target should be no more than 1/3
that of the image; it is recommended that the height of the target should be set to 10% of the
image height.
The brightness difference of the target and the background should be no less than 10 gray
levels.
The target should be continuously present in the image for no less than 2 seconds, and the
moving distance should be larger its width and no less than 15 pixels (CIF image) at the same
time.
Try to reduce the scene complexity as much as condition allowed; it is not recommended to use
Intelligence Behavior Analysis in scenes with intensive targets, changing lighting conditions or
small difference between target temperature and scene temperature.
For thermal channel, try not to monitor scenes with glass. For visual channel, try not to monitor:
scenes with reflective surfaces such as glass, bright ground or water; scenes that disturbed by
tree branches, shadows or winged insects; scenes that against light or under direct light
exposure. Control image proportion of objects that are with high relative ambient temperature.

Configure Smart Plan
Select a preset for which you can enable the intelligent rules (tripwire, intrusion, abandoned object
or missing object) first. Then you can configure detailed settings.
Go to the
Live
interface and select
Preset
in
PTZ function
box. Then select a preset number and
click
to examine whether or not it’s the scene where you want to set intelligent
rules. See Figure 4-49. If not, go to
Setting > PTZ > Function > Preset
to add a new preset.
