Description
is set to Auto. Choose a 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 85.
The Input option is available only when the Switch Mode is set to Night
External. Choose the Input port that is connected an external device that is

The Start Time option is available only when the Switch Mode is set to Night
Schedule. Enter the time, in 24 hour format, when the camera disables its

Check this check box to enable the camera tamper feature.
When enabled, this feature causes the IP camera to generate alerts when any
of the following events occur and persist for a designated period:
The IP camera view is changed
•
The IP camera view is blocked
•
The IP camera view is substantially out of focus
•
Enter the minimum length of time that a tamper event persists before a
tamper alert is generated. To prevent false alerts, the IP camera waits for this
period after detecting a tamper event before it generates an alert. If the
tamper event is resolved (the IP camera view is returned to its original
setting, the IP camera view blockage is removed, or the IP camera is put back
in focus), an alert is not generated.
Valid values are 10 to 600 seconds.
