Alarm-in is the alarm input port; users are able to connect sensors such as infrared sensor
(PIR), 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 an alarm siren, alert lights or electric strike to this port. Under normal circumstances, the
circuit is open. When there is an alarm event, the GXV3662_FHD will close the circuit to
trigger the alarm.
