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.
