3.5 Alarm Setup
Certain devices support alarm inputs and outputs, check your specific device for alarm capability.
Alarm Input
Refer to Figure 3-3 for alarm input configuration. The device collects that status of the alarm input port
when the input signal is idle or grounded. If the input signal is connected to the 3.3 V or it is idle then
the device receives the alarm input signal. If input signal is grounded, then no alarm input signal is
detected.
Alarm Output
The ports ALARM_OUT and ALARM_OUT_GND form a switch that is used to provide alarm output.
Normally the switch is on. The switch turns off when there is alarm output.
Making Alarm Connections
1. Connect the alarm input device to the ALARM_IN_1 or to the ALARM_IN_2 connector.
2. Connect the alarm output device to the ALARM_OUT and to ALARM_OUT_GND connectors.
Note: the ALARM_OUT port is the relay switch output. Connect only a Normally Open (NO) alarm
device to the ALARM_OUT port.
3. Launch Internet Explorer and type the camera IP address in the address bar. Internet Explorer
opens the Login page.
4. Type the Username and Password for the camera. (The default Username and Password is
"admin "). Then, click Login.
