Description
Choose the day/night mode for the IP camera:
Day—IP camera always remains in day mode.
•
Night—IP camera always remains in night mode.
•
Auto—IP camera automatically switches between day and night mode
•
based on the lighting condition threshold that you specify.
When the IP camera is in Auto mode, it attempts to avoid frequent or
unnecessary changes between day mode and night mode (such as can
occur when an IP camera is set up on a street where car headlights could
cause constant changes between these modes). When the IP camera
detects that a switch from day to night mode might be necessary, it
monitors the light level for 10 seconds. If the light level remains below
or above the configured Day to Night Threshold for the entire 10
seconds, the IP camera switches modes. Otherwise, the IP camera
remains in the current mode.
If the IP camera goes through 3 day/night mode transitions within a 60
second period, the camera stops detecting and implementing day/night
changes for a period of 5 minutes from the point of the third transition.
During these 5 minutes, the IP camera remains in the current day or
night mode.
Night External—IP camera switches to night mode based on external
•
Input port. It switches to day mode when the external Input port is not
in the triggered status. Check the external Input port of "Alarm I/O
Ports." Output port is optional and can be used to trigger devices
connected externally.
• Night Schedule—IP camera switches to and from Night mode based on
the Start and End times. Start Time - Enter the time, in 24 hour format,
when camera enters Night mode. End Time - Enter the time, in 24 hour
format, when camera exists Night mode.
If you configure a Night Schedule, make sure that the time on the IP
Note
camera is set correctly.
is set to Auto. Choose a 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 45.
