CONFIGURE ANALYSIS SETTINGS
Motion detection
You can configure settings to generate an event signal when a motion is detected.
1. From the Setup menu, select the <Analytics (
)> tab.
2. Click <Motion detection>.
3. Set whether or not to <Enable Motion detection>.
4. Set an <Area> and <Exclude area>.
You can set up to 8 areas.
You can configure level, sensitivity, and handover settings for
each area of interest.
A single area supports a shape with up to 8 vertexes.
Select 4 vertexes on the video using the mouse to create a
rectangle, and select each line of the rectangle and add up to
4 more points to create a desired shape.
5. Configure settings for each item.
• Level of detection : If the motion is greater than the level configured, a motion detection event is
generated.
Even on the chart, if the motion is greater than the boundary of the level configured, the color is
displayed differently.
• Sensitivity : Sets the sensitivity of motion detection for each area. Decrease the sensitivity in an
environment where the background and the object are clearly distinguished, and increase the sensitivity
in a dark environment where the background and the object cannot be clearly distinguished.
• Hand over : If you select <Enable> for the handover, you can inter-operate the motion detection with
an additional network camera featuring the PTZ preset function. When a motion is detected, the inter-
operating PTZ camera moves to the specified position to perform monitoring.
• Receiver camera : Register a camera to inter-operate with the motion detection. Press the [Add] button
at the top of the menu and enter the IP, port, ID and password of the camera as well as the preset
number to move to when a motion is detected.
`
Camera operates properly only when a preset that is set to the receiving camera is specified.
`
Handover supports only 1 preset for each area.
6. Configure the event motion schedule and event motion conditions.
`
For more information about <Event activation time> and <Event action settings>, refer to “Alarm input”. (page 50)
7. When done, click [Apply].

`
Detected size of an object may have difference with the actual size according to its shape.
`
In the following cases, motion detection performance may be impaired or a malfunction may occur.
-
The object color or brightness is similar to the background.
-
Small activities around the border area of the camera’s field of view.
-
Multiple movements continue occurring at random due to a scene change, rapid lighting changes or other reasons.
-
A fixed object continues moving in the same position.
-
Motions of less position changing such as approaching to the camera or fading away from the camera.
-
Moving object approaches to the camera too close
-
An object hides other objects behind.
-
Too fast object (for a proper detection, one object should be found overlapping between contiguous frames).
-
Reflection / blur / shadow due to a strong light such as direct sunlight, illumination, or headlamp.
-
In severe snow, rain, wind or in dawn / dusk.
Tampering detection
You can set to detect tampering attempts and trigger events, such as sudden change of camera’s framing
direction, blocked lens and other overall change of scenes from the video.
1. From the Setup menu, select the <Analytics (
)> tab.
2. Click <Tampering detection>.
3. Set whether or not to <Enable Tampering detection>.
4. The chart represents the degree of tempering. Set the level
sensitivity of tempering to detect (range: 1 to 100).
5. Set the sensitivity.
The higher the set value, the more sensitive the camera
reaction (range: 1 to 100).
6. Specify the minimum monitoring duration.
An event signal is generated if a state higher than the detection level remains for the minimum monitoring
duration (unit: seconds)
7. Specify whether to exclude dark areas.
This function makes it difficult to distinguish darkness due to de-illumination from darkness due to being
blocked by an object. Despite this property, if you want to exclude an alarm for sudden changes in screen
brightness such as de-illumination, you should enable this function.
8. Configure the event motion schedule and event motion conditions.
`
For more information about <Event activation time> and <Event action settings>, refer to “Alarm input”. (page 50)
9. When done, click [Apply].
J
`
The detection will be restarted after stabilization for a certain period of time (about 5 seconds). During stabilization, detection
is not available.
`
If false alarms are frequently generated, you should gradually decrease the sensitivity to minimize false alarms.
`
If you use a low sensitivity, alarms may be generated even by very small changes on the screen, but false detection may
occur in response to changes in moving objects or brightness.
`
In the following cases, the tempering detection function may malfunction.
-
Monitoring environment with simple background, night and low light level environment.
-
Severe camera vibration or sudden lighting changes
