Forces Night mode, and disables Day mode.
•
Switching Gain.
Determines the level of darkness required for the camera to switch from
Day to Night mode when the
Day/Night mode
is set to
Auto
. Small values cause the camera
to switch to Night mode when there is still a lot light in the scene, and larger values cause
the camera to stay in Day mode much longer.
TIP
For AV3130 and AV3135 units, you can set the gain from 0 to 18, and for other units you
can set it from 64 to 512.
•
Toggle Guard.
Adjusts the level of brightness required to switch from Night to Day mode.
This setting should be adjusted to prevent the camera from toggling modes during transi-
tional lighting periods.
TIP
Setting this option to
0
corresponds to the camera switching at 100%. For AV3130 and
AV3135 units you can set the toggle guard value from 0 to 6, and for other units you can set
it from 1 to 4.
Configure flicker control
The flicker control feature prevents flicker caused by lightning power line frequency.
NOTES
•
This setting has no effect when the dominant light is sunlight.
•
This setting loses effect if the camera’s
Low Light Mode
exposure option is set to
High
Speed
, and the
Short Exposure
value does not match the power line frequency. The
Short
Exposure
value matches the power line frequency when it is close to a multiple of 8.3ms for
