Alarm In 1 through 4
This NVR is capable of responding to event signals
from external alarm in devices. Connect mechanical or
electrical switches to Alarm In 1 through 4 and the G
(ground) connector. In order to be recognized by the
NVR, the signal from an alarm in device must be less
than 0.3V (Normally Open) and maintained for at least
0.5 seconds. The alarm in voltage range is 0V to 5V.
