The virtual I/O port feature can be used for advanced integration between physical I/O inputs and software events.
Virtual I/O ports can be defined for I/O Devices or Camera I/O:
•Virtual Ports: Set the number of virtual ports for this device
•Initial State: Set the initial state of this device's virtual ports
With virtual I/O it is possible to combine one or more physical alarm inputs with one or more virtual I/O ports, with this it is possible to define, for example, that for an event to occur it is necessary that the alarm input be activated (through of the physical input) and a software event occurs (for example an analytics, or an LPR event) and changes the status of the virtual port.
In the example below we are specifying that the input event "Trigger alarm" will occur when device port 1 is closed and virtual port 1 is closed. Device port 1 will be closed through a dry contact (for example connected to a door, a motion sensor, temperature sensor, etc...) and virtual port 1 will be activated through the analytics.
To activate the virtual port, you need to create an exit script that activates the port:
And this script can be called by any system event, such as an analytics presence detection (Or even via API):
Virtual I/O is an excellent tool that can be used to create complex automation and alarm scenarios by combining logical and physical events. As it is a complex feature, if you have difficulty configuring it, contact our support team and we will help you succeed.
