1、The normal code flow and alarm code flow on the NVR are template, as long as with IPC network continuously, will not change, no matter whether there is an alarm
2、The NVR and IPC break and connect , then boot , will be access code from the IPC
3、When the alarm occurs, the IPC code flows into alarm code flow; Alarm disappears, the IPC code flow recovery for commonly used code flow;Time delay before and after 10 seconds
4、Only when the alarm, the IPC and NVR broken network, after connect, NVR commonly used code flows into alarm code flow, and have been turned back commonly used code flow
