history
level.
• To only detect flashing light, low
sensitivity
can be selected. In other cases, a high
sensitivity

Port Status
Under
Event Configuration > Port Status
, there is a list that shows the status for the
connected inputs and outputs of the Video Server. This is for the benefit of an operator,
who cannot access the System Options section.
Example:
If the Normal state for a push button connected to an input is set to Open circuit, as long as the button is
not pushed, the state is inactive. If the button is pushed, the state of the input changes to active.
If there are parts of the Include window that you wish to exclude, click the
Configure Excluded Windows
radio button and repeat steps 1-8 above.
