be outputted.
`
EXTERNAL : Send signals through external terminals.
`
OSD : Display signals on the screen.

RETURN : Return to the INTELLIGENCE menu.
y
RETURN : Return to the VIDEO ANALYTICS menu.

`
Before use, set the max/min movement size within the range.
`
Depending on the shape of an object, there can be errors in size detection.
`
From the top of the screen, a max of sixteen objects can be expressed.
`
If the camera shoots an object a short distance away, the video analysis function can be degraded.
`
In the following cases, motion detection or video analysis event performance can be degraded
or malfunctions can occur.
- If an object’s brightness or color is similar to that of the background
- If there is little movement near the screen edge
- If multiple movements keeps occurring randomly, such as scene switching or sudden light
changes
- If an object fixed in the same location keeps moving
- Moving away from the camera or approaching the camera. Little location change on the
screen.
- If a moving object approaches the camera
- If random objects obstruct the view of each other
- If more than one objects merge or one object divides into multiple objects
- If an object moves too fast (the same object should have overlapping areas between the
consecutive frames)
- If there are reflections/blurs/shadows created by a strong light such as direct sunlight,
lights, and headlights.
- Severe snow, rain and wind. Sunset or sunrise
- If the size is greater than the max size or smaller than the min size, motion is not detected.
To avoid false detection caused by noises, set the max/min detection size suitable for the
installation environment.
But the same movement in the same location can cause a different detection size. So,
include margins when you set the min/max detection size.
