Detection Time This sets the time period (in seconds) when a new reference image
will be taken. The reference image is compared to the current view to
detect any changes in the scene
i.e. object removed.
Note: Care is required when setting the Detection Time on a live site i.e. if a person is walking
through the scene when the reference image is recorded, that person will considered part of
the background scene.
Region Settings
Region To dene a region, click on the Region drop down list and select a
number (1-16). A box will now appear on the camera view. Up to 16
individual regions can be created per camera. The detection region
can be moved and resized by clicking and dragging the corners of the
box.
Analytic Type Select ‘None’ to deactivate a specic region (not all regions on
the camera).
Scale This denes the change parameter the system will use when
comparing the reference image against the current image (for the
selected region). Select ‘In pixels’ or ‘As a % of region size’.
If ‘In pixels’ is selected, the system will use the rate of pixel change
within a region to generate an alarm.
If ‘% of Region’ is selected, the system will use the percentage of the
region that changes to generate an alarm.
Min Size If ‘In pixels’ has been selected via the Scale option, enter the minimum
amount of pixel change that will trigger an alarm.
If ‘% of Region’ has been selected via the Scale option, enter the
minimum percentage change that will generate an alarm.
Max Size If ‘In pixels’ has been selected via the Scale option, enter the maximum
amount of pixel change that will trigger an alarm.
If ‘% of Region’ has been selected via the Scale option, enter the
maximum percentage change that will generate an alarm.
Note: For quick setup, Dedicated Micros recommend selecting ‘% of Region’ , a min size of ‘5’ and
a max size of ‘100’.
Min/Max Aspect Ratio: This setting allows the system to be congured to detect specic shaped
objects i.e. tall and narrow or short and wide. The text boxes allow the
minimum and maximum width to height ratio to be entered i.e. a minimum
setting of 2:1 would result in objects twice as high as wide triggering an
alarm. A maximum setting of 1:4 would limit detection to objects no more
than 4 times as wide as high.
Note: If the Min/Max Aspect Ratio settings are left at ‘0’, the function is deactivated.
Colour Each tripwire (region) can be assigned a different colour to
aid conguration.
Trigger Alarm When a trigger occurs, you can set the system to activate a Virtual
Alarm. Virtual Alarms can be used as an Input in an Alarm Zone.
