Hello!

I got Dahua NVR5208-EI2 and 3 x IPC-HFW3849T1-AS-PV-0280B-PRO.

All mounted in same high. All setting are exactly the same, the only difference is IVS draw rule placement.
All got Intrusion Type, all for both direction, sensitivity is the same.

The problem is that in Playback > Target Video and in Event Video (where event type = IVS) I am able to see data only from camera 1, not data for camera 2 or 3.
In event center I am able to see Intrusion for cam 2 and 3.

Any idea what could be wrong?
 
I formatted disc
I also change channel sorting - so now camera 1 is 2 and its still showing me data in Target Video for same camera device only
 
So if I understand the channel shows IVS video regardless of what camera is plugged into port#1 but the others do not?

Are you using On Camera IVS or By Recorder?
 
While the Hard drive format fixed many of my issues, its still full of little bugs.

I'll test that again tonight. I have it shut down currently
