Yes, we are planning to offer this as a service. Probably a monthly subscription and at a cost that is less than the cost of the electricity to power a DVR 24x7. Currently it's free as it is under development although getting close now. Just need to add multiple camera support and give the interface some TLC.
It is like an FTP server, but with the added benefit of a web interface that handles event notification and makes reviewing the historical images easy. It also automatically deletes old data and can generate email alerts.
So if you create an account, you don't need to have a PC switched on at home all the time. You don't have to setup and configure your own FTP server. (You would need to configure the camera FTP client to connect to your account). You can access the historical data at whatever broadband rate you're browser is connected at (i.e. not limited to your 1Mbps). Also, no need to open up any ports in your router so avoiding any related security issues. We have taken particular care over security and all connections are via an encrypted HTTPS link and FTPS is also available if your camera supports this mode.
Feel free to try it out and let us know how you get on.
