9. Event
9.1 Event > Alarm Port
Alarm Input - Used for connecting external alarm devices and triggering images for
specific alarm-based events. The input is typically connected to a
motion detector or any other external security device, and images could
be uploaded whenever the detector is activated. Maximum 5VDC is
allowed on the input.
Output - This could drive a maximum load of
0.5A 125VAC / 1A 30VDC
directly or
heavier loads by connecting additional relay circuitry. If the output is used
with an external relay, a diode must be connected in parallel with the load
for protection against any voltage transients.
Duration - This parameter sets the minimum tampering period, that is, an alarm will
not be triggered until this period has lapsed, even if the tampering
conditions are otherwise met. This could help to prevent false alarms for
known conditions that affect the image.
Caution! Connecting AC to the inputs/outputs will damage the unit.
