This feature is only available for camera models which have a fan. Several modes are available:

• Auto Mode
  The fan activation is monitored and the controller automatically.
• Manual Mode
  The fan activation is controlled using a specified threshold and duty cycle.
• Force On
  The fan is always on
• Force Off
  The fan is always off

Manual fan rotation

To achieve manual fan rotation, use the following parameter settings:

1. Switch "Device Fan Mode" to Manual to enable temperature thresholds and fan duty cycle
2. "Device Fan Duty Cycle" represents the PWM fan speed as a percentage.
3. Set "Device Fan Threshold High" for value in Celsius for fan ON
4. Set "Device Fan Threshold Low" for value in Celsius for fan OFF

Important note: Not all cameras equipped with a fan are able to gradually adjust 'Fan Duty Cycle', some models are limited to a binary switch where value of 0 is fan off and 100 is fan on.
