I have upgraded old laview NVR to Dahua N82B2P. My Laview bullet cameras LV-PB932F4 are plugged directly to NVR and are identified but show "login return time is up" message. I have the correct camera password but somehow it shows up as status red. Any easy fix for it? Or should I buy 8 new dahua cameras? They are not cheap and prices seems vary greatly.. Any advice on bullet camera so it can be plug&play over poe?
