Thought you were thinking of changing away from BI to an NVR? I haven't lost hope in the NVR and all these issues which are making it buggy can be fixed in a firmware update. When I set out to order all this gear I just wanted something easy which could be configured and hidden inside my data cabinet.
Recently I have been wondering if I should switch to BI. I know it's more than a fan favourite around here and the cost is attractive but something bugs me about investing in hardware for a software which seems stalled and I know that comment is going to attract a bit of heat but it's my personal observation.
Few reasons which might get me to move would be if the motion detection was smarter than Dahua's built in IVS and had the ability to privacy mask freely without having a limit of 4 boxes. Still trying to master IVS.
Also I don't believe we have the availability of these ultra-cheap desktops
@fenderman always suggests, don't hold me to this as I haven't had a good look around.
