Validation Time

If the Switch Mode option is set to Auto, specify the time that the camera

 

 

waits before switching Day/Night modes. The light level must continually

 

 

exceed the threshold for the duration of the validation time to trigger a

 

 

transition between the modes.

 

 

For example, if the Validation Time is set to 5 seconds and the current light

 

 

level exceeds the Night/Day Threshold for 5 seconds, the camera switches

 

 

mode. However, if the light level falls below the threshold during the

 

 

Validation Time, the timer resets and the camera remains in the same mode.

 

 

The default value for Validation Time is 2 seconds.

 

 

Note If a camera experiences lighting conditions that cause it to switch

 

 

continuously between Day and Night modes three times within 20

 

 

minutes (as the result of a low light scene with excessive IR

 

 

illumination or the thresholds being configured too close together),

 

 

the camera locks in to its last state for 20 minutes.

 

 

For example, if the first transition is from Day to Night, the camera

 

 

will switch from Day to Night to Day to Night and then remain in

 

 

Night mode for 20 minutes. If the first transition is from Night to

 

 

Day, the camera will switch from Night to Day to Night to Day and

 

 

then remain in Day mode for 20 minutes.

 

 

To unlock the 20 minute hold period, manually configure the camera

 

 

to Day mode, then Night mode, then Day mode, and then Auto mode.

 

 

Day to Night Threshold

If the Switch Mode option is set to Auto, choose the value that specifies the

 

 

relative light threshold at which the IP camera switches from day to night

 

 

mode. A lower value designates that the IP camera switches from day to

 

 

night mode in brighter conditions. A higher value designated that the IP

 

 

camera switches modes in darker conditions. The default value is 24 for all

 

 

presets.

 

 

Night to Day Threshold

If the Switch Mode option is set to Auto, choose the value that specifies the

 

 

relative light threshold at which the IP camera switches from night to day

 

 

mode. A lower value designates that the IP camera switches from night to

 

 

day mode in darker conditions. A higher value designated that the IP camera

 

 

switches modes in lighter conditions. The default value is 6 for Outdoor

 

 

preset and 16 for Normal, Indoor, Fluorescent and Metal Halide.

 

 

 

Start Time

 

If the Switch Mode option is set to Night Schedule, enter the time (in 24 hour

 

 

format) when the camera enters Night mode.

 

 

 

End Time

 

If the Switch Mode option is set to Night Schedule, enter the time (in 24 hour

 

 

format) when camera exits Night mode.
