Ok, so the time is rapidly approaching for us to shuffle off the mortal coil of our little food truck for the last 4 1/2 years and head to a brick and mortar location. I have been playing with BI at our house setup for about 8 months or so with a pre existing laptop that I have I7-7700 with no issues running 6 cameras. Depending on the size of the building that we eventually decide on,I will need the scalability of up to 20-24 cameras including audio options for the interior of the building. I plan on using 4mp cameras for the clarity with digital zoom (cash drawer, tables, etc). A few of the questions are: *Would stand alone microphones be better than integrated units with the cameras? *How many channels/cameras of audio is BI capable of recording? *I'm thinking of domes for the inside and bullets outside (I don't like the halo effect from domes using IR) is this good? *With that many cameras is processor only video good enough or should I look for an additional video card? *Is it critical for RAID 5 on storage drives or should I just run a RAID 0 setup?
