Scan Limits
Scan Limits are two points around the dome’s pan
axis, which define a surveillance area. When
active, the scan repeats until interrupted by a
camera command, preset, pattern, or alarm.
Figure 4 provides an example of scan limits for a
dome installed over the edge of a building
monitoring a parking lot. In this example, the
building blocks part of the dome’s viewable area.
Figure 4: Scan Limits example
The dashed circle represents the dome’s field of
view. The solid line curve represents the scan
area. By setting the left and right scan limits where
the building’s wall becomes visible, you ensure that
only useful video of the parking lot is being
observed when the scan is active. Once these
scan limits are programmed you can choose to run
a smooth scan, stepped scan, or random scan.
Table 2: Scan Types
Smooth Scan An automated scan that slowly
pans between the left and right
scan limits, starting at the left
scan limit. When the right scan
limit is reached, the scan
reverses.
Stepped Scan An automated scan that pans
slowly pausing briefly every 10°
between the left and right scan
limits. Once the right scan limit
is reached, the scan reverses.
Random Scan An automated scan that pans
randomly between the left and
right scan limits, starting at any
point between the scan limits.
If your controller supports the Quick Set menu
function, you can program left and right scan limits
to automate your surveillance activities. The Scan
Limits menu option is found on the Alarms/Areas/
Home/Presets/PZ menu.
