5 Alarm Configuration
The Camera can link to alarm output devices to report alarms when alarms are triggered from
external alarm input devices.
Cut off the power before connecting the cables.
Step 1
Connect the alarm input device to the alarm input port of I/O cable.
Alarm input: Receives on-off signals from external alarm devices, and supports NO and NC
alarm input. The input signal is idle or grounded, and the Camera can collect different
states of the alarm input port.
●
When the input signal is 3.3 V or idle, the Camera collects logic "1".
●
When the input signal is grounded, the Camera collects logic "0".

Step 2
Connect the alarm output device to the alarm output port of I/O cable.
Alarm output: Port ALARM_OUT and GND form a switch to provide alarm output. The
switch is normally on and has a high resistance. ALARM_OUT is connected to ground when
there is an alarm output.
