I have been struggling with the Video Detect settings for quite awhile. Specifically, the "Area->Setup" settings. BTW, I have two IPC-HFW4300S-V2 cameras that I have been experimenting with. Anyway, the menu gives you four "Regions" to define with their own sensitivity and threshold settings. So, what I do to set up these two parameters in one "Regions" is to select the whole picture. If its the first region, the whole checkerboard picture is populated with red hash lines. Next, I select a sensitivity level. I first select 100 percent, and watch what, I get when I walk near the camera. I lower it to a reasonable level so that moving leaves do not cause a spike on the recording graph. I then lower the "Threshold" setting so that only my walking in front of the camera causes a detection spike to show above the threshold line. However, I find that the next day, I have about 100 email alerts. I log back into the camera, and find that the sensitivity level that I chose the previous day was too high, and the threshold too low. In other words, it seems that I have to wait 24 hours between settings, and results. Can anybody shed some light on how to set the Video Detect settings?
