Dahua Alarm In

Recommended Posts

Hi, I have a client which requires me to configure a system that is rather difficult for me to comprehend, look forward to some help here from the gurus here.

 

He has an IP camera IPC-HFW3200 with alarm I/O panel, then a NVR3216.

 

He wanted to connect a push button to the IPC's alarm I/O, specifically Alarm in 1 and GND.

 

The reason being that he wants to activate the recording only after he pushes the button.

 

Problem is, the SD Card in the IPC starts recording when he pushes the button, but apparently it didn't trigger the NVR to start recording.

 

Have any of you done a system similar to this before?
