If you use the AcuSense feature built into to the cameras (use device VCA unticked) there's no need to do anything. The camera is processing the events and only sending them to to the NVR if the conditions are met. The camera can be configured to filter events based on human/vehicle for motion detection, line crossing and intrusion detection simultaneously if more than one event type is configured for that camera.
If you use the AcuSense feature built into the NVR (use device VCA ticked), the NVR engine can either be used for motion detection, OR perimeter detection (line crossing/intrusion) to filter events based on human/vehicle. Any camera can be used and the event is sent to the NVR without regard as to whether there's a human/vehicle present. The NVR event engine then applies filtering to each incoming event, only performing the configured actions if the human/vehicle filter is matched. Because the processing capabilities of the NVR are finite, there are limitations:
- You can't have both motion detection and a perimeter detection (filtered) event on a camera IF using the NVR VCA engine (as you have to set one or the other in the NVR page you've shown)
- You can't have filtered motion on one camera and filtered perimeter detection on another IF using the NVR VCA engine (as you have to set one or the other in the NVR page you've shown)
Generally you would always use the AcuSense feature in the camera (use device VCA unticked) on any channel where the camera has the AcuSense feature (so if all of your cameras are those 2143G2's, set it up this way and forget that the NVR has that feature as it's less restrictive to use the cameras inbuilt functionality)
Alternatively if you have a mix of old/new cameras without/with AcuSense capability; you would use the AcuSense feature in the camera (use device VCA unticked) on the capable cameras. On the cameras that aren't capable you would use the feature in the NVR (use device VCA ticked), decide whether motion or perimeter detection was more important and select that option in the page you've shown prior to setting up the events.
Primarily the NXI models have the feature as a means to upgrade an existing system where the existing cameras don't have the capability.
