| |
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. |
