Newbie trying to understand Dahua NVR/camera-logic

Hi there,

I have been using two cams of type "Lupus LE232", which are actually branded Dahua cameras. Since they are not updated by Lupus I got the recommendation to use a Dahua NVR to benefit from a more recent and more intelligent detection of humans.

I therefore bought a Dahua DHI-NVR5208-8P-EI and connected the cameras to it. When now chosing "Event | AI Settings | IVS" I can see all the features I configured directly in the cameras before, now being able to configure both cameras at the same time in the NVR.

But actually the behaviour/detection of the cameras did not change at all. To me it seems the cameras are still interacting on their own and not that the NVR is doing anything more intelligent.

I saw that in the "IVS"-view there is not a "Type" field as in several other screenshots. In that "Type"-field one should be able to chose between "AI by Camera" and "AI by Recorder".

After changing "AI Settings | Smart Plan | Recorder | Mode" from "AcuPick" to "AI Mode" and rebooting the NVR, the "Type"-field is now displayed.

When chosing "AI by Recorder" I guess the NVR is handling the camera stream and doing the intelligence, am I right?

But when leaving "IVS"-view, chosing e.g. "SMD" and then "IVS" again, channel 1 is showing "AI by camera" again, although I selected "AI by Recorder" and applied the settings before.

Can somebody explain what is the best way to configure those cameras with that NVR? Are both camera and NVR IVS working in parallel? Or do I have to disable the camera AI at some point?

Thanks for clarifying and helping a newbie out ;)

Best regards,

1. first don't mix SMD and IVS... use only IVS, SMD disable..

2. if You enabled IVS with AI by Recorder, log to camera web panel and check is IVS disabled on camera? if not, disable it... IVS done on NVR is enough...
