1. Both the camera's and NVR support Human Detection as both a Basic and Smart event, what is the difference? If I enable both, I don't get 2 events for each time a person passes by the camera, so it seems only one is active?

2. My cameras are connected to a NVR1008H. If I enable/disable events in the NVR's web interface, the camera's web interface doesn't stay in sync. So I can enable vehicle detection on the NVR, but it won't be on in the camera's web interface. Does this mean that the NVR actually does the detection, not the camera? Can I keep everything disabled on the camera?

3. Is it required to enable motion detection on the camera for the auto fill light feature to work?
