What type of server would I need to allow video storage from many subscribers' video cameras? I would need a way for customers to log on and watch their videos from other pc's and download those videos if needed. Videos would be stored for up to 30 days for as many customers as possible and be expandable. Would I be able to limit access only to customers with the same server or would I need another for that?

Thank you for your help,

Mark

You need a big, fast server.
There are many sites that offer video hosting and you'd be much better off outsourcing this project, which can be very expensive and time consuming.
Google "Video server host" or something similar to find some offers.
