11. Event
11.1 Alarm Port
Alarm Input (dry contact)
Used for connecting external alarm contacts and triggering specific alarm-based events. The input is
typically connected to a motion detector or any other external security device, so that recording can
be triggered and/or still images could be recorded and/or uploaded whenever the sensor is activated.
Enable or Disable the alarm input and define it as Normally Open (N/O) or Normally Closed (N/C).
Name the alarm in the Text field.
Alarm Output (relay output)
This could drive a maximum load of 60 VDC or 120 VAC at 2 A directly. 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. Enable or Disable the alarm output and select a mode of SYNC or LATCHED.
Duration
This parameter sets the minimum period before the alarm resets. Another 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 will damage the unit!
