Unlike the Alarm_Out interface of Grandstream IP Camera (e.g.: GXV3611IR_HD or GXV3662_HF/FHD
where the related Alarm_Out interfaces are using relay switch), the GXV3500 Alarm_Out is using
photocoupler circuit.
If connecting to a multimeter, you will see the Ohm changed from unlimited to serveral hundred Ohms
depending on GXV3500 HW version.
