GXV3501/GXV3504 Alarm Event
The GXV3501/GXV3504 supports alarm inputs, for example, infrared detector, smoke

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.
NOTE: GXV3504 has 4 individual Alarm Event settings for each channel.
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.
