Enable/Disable "Notify Surveillance Center" via ISAPI

I don't use it, but the NVR has functionality specifically designed to get a signal from an alarm system...

Does your alarm system have an output that could be tied to the NVR "Alarm Input"? Then you could use...

One more thought... if you don't have an output from the alarm system or can't run a wire from the alarm system to the NVR, maybe you could configure the "Alarm Input" the way you want and then use ISAPI to toggle "Alarm Type" between NO/NC (normally open, normally closed) mimicking the signal from the alarm system.
