GXV3501/GXV3504 Alarm Event

The GXV3501/GXV3504 supports alarm inputs, for example, infrared detector, smoke detector and
so on. Follow the steps to make Alarm Input work:
1. Connect alarm input equipment to the GXV3501/GXV3504.
2. Set up the alarm event time schedule.
3. Configure the alarm actions which you would like the GXV3501/GXV3504 to take when
alarm is triggered.
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 GXV3501/GXV3504 will close the circuit to trigger the alarm.
