If you select the Enable digital zoom checkbox, you will be able to zoom in on an image by up to 360X
magnification with the combination of the 30x mechanical zoom and another 12X digital zoom.
The Freeze image during patrol skips the display of the process when moving from one position to
another. Only the preset points are displayed.
Focus mode: This determines how focus takes place when camera lens is ordered to aim at different
areas or preset points, or zoom in or out on a scene.
Auto : Firmwar e automatically adapts to different environments regarding the distances of objects in
scene, and generates the best focus results.
One-time focus : Because image blurs can occur during a repeated focusing process, onc e moved to
a scene (a preset point), the camera exerts only one automatic focus in this mode. This applies when
use rs prefer an expected depth of field and prefer the view not to be affected by the continuous focusing
acts resulting from moving objects in the scene. The One-time focus applies when using presets and a
general imaging result is expected without focusing near and far.
Spotlight avoidance : The Spotlight avoidance mode automatically avoids the interferences of strong light
sources such as spotlights in a stadium or road lamp in a dark scene.
Manual : 1. When applied and moved to a position, a manual focus action is required.
2. The second scenario applies to the use of an intelligent video analytics software which may utiliize
an independant focusing algorithm. If such a 3rd-party software is implemented, none of the above
focus modes apply.
Apply previous action if the camera idles for __(1~999) seconds : You can assign an action to be
taken when the camera sits idle for a configurable period time. For example, you can let camera resume
a patrol tour. The resumed patrol will continue from the last preset position. You may also let the camera
return to the home position. The idle state does not include the situations when the camera is performing
pan or patrol action.
Return to home position : When no activities occur after a configurable period of time, let the camera’s
lens return to the default home position.
Washer options: Select Washer or Wiper. The Washer mode requires a washer kit that is externally
mounted. The camera should move to a preset point where the washer kit will spill water onto it and with
the help of the wiper, wash dirt from the lens. Note that a washer action should not apply to a freezing
environment.
Washer dwelling time: The default dwelling time is 15 seconds, whic allows the wiper to move twice
across the lens and IR lights surface. You can change the default value for more wipes across the
surface. A 4 seconds lapse exists between wipes.
