1800 and 3600 seconds. If DO is triggered, in this time interval, DO will keep on 
triggering. 
[Action] 
There are 6 actions that are related to the DI/DO functions. 
  DI →Camera Recording 
When DI is triggered, DVR can start to record the video of selected cameras. You can 
select the cameras to be recorded when DI is triggered by using the “DI/Camera array” 
shown below the setting. Each DI signal can trigger more than one camera recording. 
  Cam Motion →DO 
When selected camera detects motion, selected DO can be triggered and start to send 
control signal to the external device (e.g., alarm) within the DO duration. The 
“Camera/DO array” below the setting allows you to relate the DO devices corresponding 
to each camera. 
  Cam V-Loss  →DO 
When selected camera video is lost, selected DO can be triggered and start to send control 
signal to the external device (e.g., alarm) within the DO duration. The “Camera/DO array” 
below the setting allows you to relate the DO devices corresponding to each camera. 
  DI →DO 
When selected DI is triggered, selected DO can be triggered and start to send control 
signal to the external device (e.g., alarm) within the DO duration. The “DI/DO array” 
below the setting allows you to relate the DO devices corresponding to each DI. 
  System Event →DO 
There are two types of system event. One is “ System Warning” and the other one is 
“System Error”. When system event occurs, selected DO will be triggered and start to 
send control signal to the external device (e.g., alarm) within the DO duration. The 
“Event/DO array” below the setting allows you to relate the DO devices corresponding to 
each system event. 
  DI →Zoom 
When selected DI is triggered, selected camera will be triggered and its image will be 
zoomed in the “Motion/Alarm Zooming area” (refer to Chapter 3-2). 
  The following figure may help to understand the concept described above.
