Sensitivity
The
Sensitivity
refers to the acceptable deviance between the compared images.
If the
Sensitivity
is set very high, a minor deviance is enough to detect a motion event.
In this case small motions can be detected. But minor deviances often are caused by al-
ternating ambient conditions (brightness, precipitation). Many false messages have to be
anticipated.
If the
Sensitivity
is set very low, the images have to differ very much. Only distinct motions
will be rated as an event. But only few false messages can be anticipated.
Decay time
The
Decay time
determines how long a motion event is valid. If an additional motion event
is detected in the same image section before this period expired, it will not be rated as a
new event.
This setting allows to reduce events that are caused by repeated motions of the same
object.
Validity period
This option is not integrated in the current version.

Camera control
Suitable dome / PTZ-cameras can be controlled and configured with the recorder’s gra-
phical user interface (see documentation
Operation
) or with a connected external PTZ
keyboard (see separate documentation). Depending on the camera various connection
types can be used:
• Connection via serial interface and a DNI (Dallmeier Network Interface)
• Direct connection via the serial RS485 interface.
• Connection via video cable with UTC.
