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.
4. Select the recorder’s input port if you would also like to use the
recorder’s input port for event trigger. And then select the trigger
condition as well.
5. Next, select the recorder’s output port and define its trigger state
6. Finally, define the trigger duration.
*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.
* The image(s) that are uploaded to the destined FTP server or emailed to a destined
mail recipient are in their own proprietary image file format (.h4i or .p4i), which can
only be opened by the NVR media player.
