The alarm connection to the rear of the WiFi Network Camera contains 4 connections:
1) Alarm output (GND)
2) Alarm output (+5V)
3) Alarm input (Source)
4) Alarm input (GND)
An external device such as an alarm unit, a siren or a door opener can be connected to the
alarm output (1 and 2). A signal is emitted as soon as the digital output is switched on
manually or where the digital output has been selected for alarm messages and the
WiFi Network Camera detects an alarm.
An alarm is triggered if the contacts of alarm input (3 and 4) are externally connected to
each other. A connection can be produced via a switch or relay, such as a motion sensor or
other alarm triggering devices. If an alarm signal has been applied, a signal is emitted
according to the above settings.
