• To trigger motion detection as long as there is activity in the area, select a high history level.
• To only detect flashing light, low sensitivity can be selected. In other cases, a high level is recommended.
Port Status
Under Event Configuration > Port Status there is a list showing the status for the camera’s
input and output. This is for the benefit of Operators, who cannot access the System
Options section.
Example:
If the Normal state for a door push button connected to an input is set to Open circuit - as long as the
button is not pushed, the state will be inactive. If the doorbell button is pushed, the state of the input
changes to active.
