Chapter 3 Configuring and Managing the IP Camera
Feature Setup Windows
IO Ports Settings Window
The IO Ports Settings window lets you configure various options for the two input and two output ports
on the IP camera. A state change of an input ports triggers a camera to take configured actions. Output
ports send signals that can control external devices, such as alarms or door switches.
The IP camera can trigger an action only when the input that is received on an input port comes from a
contact that is in a normally closed condition. The camera triggers the action when the contact changes
to an open condition.
To display the IO Ports Settings window, access the configuration windows as described in the
“Performing the Initial Setup of the IP Camera” section on page 2-5, click Feature Setup, then click
IO Ports.
If you change the option in this window, you must click the Save Settings button to save the change. If
you do not click this button, changes are not retained when you exit the window. Save Settings appears
at the bottom of the window. You may need to scroll down to it.
Table 3-5 describes the option in the IO Ports Settings window.
Display Text If you check the Enable Text Display check box, the text that you enter in
this field appears as an overlay on the video image from the IP camera.
The text can contain up to 26 characters, which can include letters, numbers,
