CCTV And Video In The Cloud

Hi All,
I have to do a presentation on CCTV and Video in the Cloud and it has to cover, this is for a course i am taking at Uni.
Technology high level overview
Who is in the market (Suppliers & Manufacturers) – what are their main products and USP’s?
What is the purchase / commercial model?
What are the likely costs?
What is the market opportunity? Who is this currently targeted at?
What will it displace?
What is the skill base required for install / service?
Who is currently using this technology in real life?
What would your recommendation be – Is it a good product?,
Should we be taking notice? If so, of who and why?

Does anyone have anything input into this or can point me in the right direction to start getting facts and details.

Thanks in advance
