that the preset mapping applies to (see below)

If you want a dome or pan and tilt camera to go to a preset on alarm, specify the preset here
for each alarm input. Set to "None" if no preset is to be invoked.

9.4.2 Activity Detection
9.4.2.1 Activity Zones
Activity detection zones may be set for each camera.
Use the UP, DOWN, LEFT and RIGHT keys to move the screen cursor around and the
OK key to toggle between setting zones and clearing zones.
Where zones are set, activity will be detected.
Use the number keys to enter the sensitivity and number of pixels that have to be active to
trigger an alarm. For example enter 62 to set the sensitivity to 6 and the pixel count to 2.
The higher sensitivity setting, the more sensitive the activity detection is.
The higher the pixel count, the less sensitive the activity detection will be to false triggering.
