Good morning, I have a swann system NVW-480 with 4 Wifi cameras.I got it set up to send emails. After the first snow fall last night, I got 45 emails... on each pictures , you can see the snow flake coming down like a white stripe which trigger the alarm. I have the sensitivity to LOW. Stream type to Fluent, Resolution to Q720P (the only one available) Frame rate at 6 and max bitrate at 192. Any suggestions?
