9.4.1 Activity Detection
Activity detection zones may be set for each camera.
Use the
UP and DOWN keys to highlight different rows.
If you select the top (text) row, the sensitivity and pixel count can be set.
The sensitivity affects all selected pixels (zones). The higher this setting, the more sensitive
the activity detection is.
• Use the NUMBER keys 1-4 to set sensitivity (Sen)
The pixel count specifies the number of zones that have to be simultaneously active in order
to trigger an activity alarm (i.e. the higher the pixel count, the lower the chance of triggering)
• Use the NUMBER keys 5-9 to set the number of pixels (Pix)
As you select the various rows over the image, the
NUMBER keys turn the zones across
the line on and off. If a zone is turned on, it will be sensitive to changes in the image.
The
DEF key may be used to toggle all zones one or off.
