ESV4 User’s Manual 97
DI 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 camera’s output port.
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.
*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.
