# IVA, # Loitering
# XNF-9013RV
1. Installation Cases
- The IVA loitering detection option was enabled after installing the camera, XNF-9013RV, for the security around the building
2. Symptoms
- Loitering detection was set by specifying the IVA area, but the event was not detected.
- Conditions: Object-Person, Categories-Loitering, minimum duration (s)-minimum value (10 seconds)
- Result: The event was recognized as ‘motion detection’ rather than ‘loitering detection’.
3. Causes
- Since the object to be detected does not show its continuous movement, it does not meet the loitering detection conditions.
- In the following cases, the target loitering object became undetectable as the system considered it disappeared.
a. When the target object didn’t move for a certain period of time
b. When the target object overlapped another object
c. When the environment was complex because there was a moving object in the vicinity of the target object
4. Measures
- Set both ‘Loitering’ and ‘Enter’ conditions for IVA
