Cameras PowerLine Frequency
If your camera supports power line frequency anti-flickering, the camera is able to 
compensate for any flicker noise from the electrical power supply. You should set this 
camera configuration based on your power line frequency. If your camera supports auto 
detection of line frequency, you can select the Auto option in the configuration.
All Cisco Precision cameras support both anti-flickering and auto detection of line 
frequency. Auto is the default value, so you should change this setting if you have a camera 
that does not support auto detection.
Requires user role: ADMIN, INTEGRATOR
Default value: Auto
Value space: 50Hz/60Hz/Auto
50Hz: Use this value when the power line frequency is 50 Hz.
60Hz: Use this value when the power line frequency is 60 Hz.
Auto: Allow the camera to detect the power frequency automatically.
Cameras Preset TriggerAutofocus
The current position (pan and tilt), zoom and focus are stored with a preset. Use this setting 
to determine if the camera should refocus or use the focus value that is stored with the 
preset.
Requires user role: ADMIN
Default value: Auto
Value space: Auto/Off/On
Auto: Whether the camera refocuses or not when selecting a preset, depends on the 
camera type.
Off: The focus value that is stored with the preset will be used. The camera will not 
refocus when selecting a preset.
On: The camera will refocus when selecting a preset. The focus value that is stored with 
the preset may be overridden.
