Appendix A
Circuit Diagram of the Sensors
SENSOR:
The build-in switch sensors in the WebCam Server are NC (Normal
Close) sensor. It’s just like the sensors which are used on doors or
windows. Usually the doors and windows are closed, but when the doors
or windows are opened the circuit becomes “open”, then the security
system in the WebCam Server will be active by the way you set it in the
“SECURITY SETUP”.
ALARM:
The alarm output sensor in the WebCam Server is a NO (Normal Open)
sensor. Which means when the alarm is triggered the circuit will be
“short”, then the alarm will be active.
