Over the past few months I have been tweaking settings but can't seem to find a happy medium. So called Grey Market Hikvision DS-7608NI-I2/8P with Hikvision DS-2CD2355FWD-I x 3 & DS-2CD2335FWD-I x 1 Firmware V5.5.3 build 171018 For this thread, using the setting from DS-2CD2355FWD-I 4mm Email set up on camera not the NVR (some reason it doesn't work as good) One thing I do hate about the Hik CAM sending emails is sometimes I will get duplicate or even triplicate of the same three shots. I have line crossing detection setup to detect <---> crossing, there are times I will get an email of one but not the other crossing direction. Phantom emails in the dead of night from car headlights, not too often though. As of late, I get bombarded with emails, warmer weather has brought the critters. Looking to tweak the setting to minimize emails from critters and hopefully capture more human activity. Hope the collective minds here can help me with this.
