How Alarm Input and Alarm Output Work
Alarm-in is the alarm input port; users are able to connect sensors such as infrared sensor,
smoke sensor or light sensor to it. The detectable signal voltage range for alarm-in is from
1.8V to 15 V NOTE: Please do not connect a device that has a signal voltage that is higher
than 15V, this will damage the IP camera.
Internally, the Alarm-out uses relays as a switch (30VAC/2A); users can connect devices such
as alarm siren or alert light to this port. Under normal circumstances, the circuit is open.
When there is an alarm event, the GXV3611 will close the circuit to trigger the alarm.

Set up Alarm Actions
An alarm action is what the GXV3611 is going to do when an alarm is triggered during the
defined time period – the time schedule. The GXV3611 allows multiple alarm actions.
