Cloud video surveillance server. What will be the cost?

Question

CCTV

Good afternoon!
We want to hang 6-8 DS-2CD2342WD-I cameras in the office, the management asks to keep records for a month. Not very eager to buy a DVR. I figured on similar cameras that are already hanging, you need about 8TB of space.
I want to roughly understand the order of prices for hosting all this in the cloud.
Either a server and install some kind of video surveillance software, or something designed specifically for video surveillance initially, such as an ivideon.
Maybe someone has already encountered, orient, please!

Answer 1

An approximate calculation on the dssl website (they do not have 4MP, like your camera, so I chose 3MP and a frame rate of 25fps). As practice shows, it is quite accurate.
For such dimensions it is better to use your own server, I think. For 25TB will be expensive. But this is not accurate, it is necessary to consider which is more profitable.
Counter question: why do you need street cameras in the office? Yes, and 4mp. 2mp is usually enough for the eyes.
PS in a personal I can advise a couple of proven options for hosting "at home". My skype is on my profile.
