on my NVR5216-EI, there is a quick search feature in the playback window. you can filter between human , vehicle and animal. when trying to use this feature, the timeline is pretty much filled. there's no way any of those 3 things are in view of the camera for so much of the day. what determines the criteria for those hits? i have acupick disabled on nvr and cams, metadata is disabled, smd is disabled, motion detection is disabled. only IVS is enabled on the cams but animal detection is not enabled, and on some days there is no human or vehicle ivs detection at all yet quick search timeline is populated. what is quick search using to determine those timeline events? can the parameters be adjusted?
