With all the new megapixel cameras coming up in the market,if you take any project with more than 50 cameras, the customer usually asks for up to 3 months of recording with an average 10fps at 2 megapixel resolution.When an integrator is quoting for such a project, 20-40% of the project cost can be for the storage and this is the most "grey" area in a "cctv project proposal". This is because most customers just care about clarity of the camera.They don't realise the importance of having enterprise level storage until they have failures in 1 or 2 years time.Hence integrators make use of this grey area and quote with decent storage enclosures and filling it with cheap hard drives.So to compete with these guys, can anyone suggest combinations of economical 12, 16 or 24 bay(or more) enclosures with the type of hard drives used,which can be used in recording at least 30+ cameras 24/7 and running decently without issues.
I would appreciate it if you could mention the resolution, fps and number of cameras used also, to get a better understanding.
