hi there, DS-2cd2432f-iw is a very good option for indoor.but i have a doubt weather it will be able to produce a good sound with in built speaker. 16 ch nvr is good enough for u. for two way audio video system u will have to consider the amplification of audio as well for perfect solution.

hi there, fiber optic is the best option possible if digging is possible . u can use armored six core fiber optic from finolex.

hi there, if you can buy hikvision 8ch NVR ,it is cheaper and can do ur job efficiently.as it has a throughput of 40 mbps more over u can record and view it remotely on the phone or pc as well. hikvision 7608NISE
