First let me say that putzing with NVR's is new to me - specifically NVR's that are capable of communication with IP cameras that is.
I recently played around for the first time with such an NVR (Hikvision DS-7208HUHI-K1) and managed to connect a couple of Dahau cameras to it using Onvif. One of the cameras was already set up to do in-camera video detection (area-change detection) and I noticed that when I went to set up area detection in the NVR that the area pattern that was in the camera had somehow been transfered to the NVR for that camera. So I'm wondering - is this normal / to be expected? That the various detection methods that are set up in-camera (area change, line crossing, face detect, etc) will somehow be transfered over to the NVR and the NVR will use those same rules/settings for video recording? I would have thought that only the video stream was sent between the camera and NVR and not these sophisticated motion-detection schemes.
What is generally done in this regard? When connecting IP cameras to NVR's is it typical to turn off all in-camera detection and set everything in the NVR? Or is in-camera detection more efficient (or more sophisticated) and if you set up something like face detect or people detect in the camera, that somehow the NVR will get a trigger signal and record video segments based on the in-camera detection?
