Response time
This function provides further fine adjustments of the automatic Day/Night switching.
The response time defines the Day/Night switching delay time once the particular thresh
-
old levels are reached.
Possible values: 1 sec. – 20 min. (Default: 5 sec.)
Example:
If during the day the camera is operated inside a room with windows that face a public
road, the entire room could become very dark for a short time when a big truck passes.
Depending on the set threshold levels for the automatic Day/Night switching, the cam-
era would normally switch to night mode immediately and, moments later, back in to day
mode.
In the reverse example there would be an unwanted permanent switching to day mode
and back as soon as the headlights of passing vehicles would light up the room.
Using the reaction time setting it is thus possible to delay the automatic Day/Night switch-
ing.
