10.  Event  

10.1  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. 

Alarm Output (relay output) 

This could drive a 

maximum load of 60VDC or 120VAC at 2A

 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.  

Duration  

This parameter sets the minimum period before the alarm reset. 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!
