6. Alarm control
There are three types of alarms that the system can be configured to handle. They are external alarm,
video loss alarm, and an alarm for motion detection.
When the above types of alarms are triggered, it changes recording speed to alarm recording speed.
Video Loss alarm is enabled as a default and cannot be changed. The buzzer will sound and a “V.LOSS”
sign will be indicated on the screen.
7. External alarm connector
The external alarm functions only when the DVR has been set under recording mode. The unit has 4
input ports to receive signals from external alarms and 4 GND port for termination. When the external
alarm is triggered, currents will be grounded through the GND port to activate the external alarm.

Recording speed will be switched from normal mode to alarm mode (refer to chapter 4 for recording
settings)
D
The unit will only record from the external trigger when “A” has been selected during the specific
time frame in the scheduled recordings menu. This is also true for motion-detected recordings.
