Hi all, I am very new to HIKVISION IP Cameras. I currently bought a house that has 8 of these around the premise DS-2CD2155FWD-I . I have them all up and running. Notifying me of alerts via email. However, they seem to be very sensitive. During monitoring times I am getting bombarded with emails for any slightest thing (rain drop, bug etc.) . Does anyone have any tips and recommendations on how to go about setting this up to trust the alerts or any ways to find activity that might be occurring and recorded on the DVR?
