Make sure the target appears at least over 2 seconds continuously in the field; the movement
distance has to be bigger than the width of the target itself and makes sure it is no less than 15
pixels (CIF image).
Try to lower the complexity of the monitoring scene analysis if it is possible; it is not advised to use
IVS functions in the environment where the targets are dense and light change is very frequent.
Try to keep away from the areas such as glass, ground reflected light, water surface, branch,
shadow, mosquito disturbance and etc. try to keep away from the backlight scene to avoid direct
light.
4.4.5.2 Set Intelligent Rules
It can set intelligent rules for tracking speed dome or panorama camera after enabling IVS smart plan,
including cross fence detection, tripwire, intrusion, abandoned object, fast moving, parking detection,
people gathering, missing object and loitering detection. The following chapter is going to take tracking
speed dome as example to introduce intelligent rules.
Note
After entering the "Rule Config" interface of tracking speed dome, the PTZ lock function is automatically
enabled, the lock time is 180s, during which it can only control PTZ manually. You can manually click
"Unlock" to unlock.
4.4.5.2.1 Set Cross Fence Detection
The system will generate alarm and activate the actions which have been set when the target crosses
two fence lines according to the set direction.
The requirements of fence are shown as follows:
It doesn't support transparent fence, such as iron fence.
It doesn't support short wall (the wall height is shorter than the height of an average person).
Crossing fence includes two directions which are upward and downward.
The judgement standard of crossing fence upward is: target rectangular box and bottom warning line
intersect → target rectangular box separates from bottom warning line → target rectangular box central
spot crosses top warning line → alarm.
The judgement standard of crossing fence downward is: target rectangular box central spot crosses top
warning line → target rectangular box separates from bottom warning line → target rectangular box and
bottom warning line intersect → alarm.
Precondition
Please refer to "4.4.4 Set Smart Plan" for the IVS smart plan which has been set preset or channel.
Operation Steps
Step 1
Select "Setup > Event > IVS > IVS" and the system will display the interface of "IVS".
