I/O Settings
This function allows users to manage camera’s digital input and output
ports right from the recorder. You can setup the recorder to receive
triggers from a particular camera’s input port and trigger a device,
such as an alarm that is connected to the recorder or camera’s output
port. Cameras that do not have built-in digital input/output port can
also be configured to pair with the recorder’s DI/DO ports.
1. For cameras that come with physical digital input ports, their ports
will be listed in the far left drop-down menu.
2. Pick the desired channel for I/O mapping, and then select the
camera’s input port from the drop-down menu.
3. Select the trigger condition from the “Condition” drop-down menu.
*The recorder does not control camera's input or output ports in a way
to let you pair recorder itself with a camera's input or output port for
event receiving or triggering.
*The recorder only acts as a medium for pairing up input/output ports
between cameras and the recorder.
*Only connected cameras will be displayed in the list.
*Some cameras only allow one trigger source be configured at a time,
e.g.:
if the camera has the motion detection function turned on, its digital
input will be disabled and vice versa. Under such circumstance, if you
set to use camera’s digital input port as the event trigger source, you
will not be able to select motion detection as the trigger source for this
camera under “Event Configurations” >> “Event Trigger” setup page.
