Well, the time has arrived! 2011 will be the year that Saas for IPVS was made practically available for a reasonable number of cameras (up to 8 with reasonable quality and low framerates).
Axis communications has made it easy and inexpensive to attach and record their camera images (or analog cameras connected to Axis video encoders) via any fast Internet connection. You can also optionally record better resolution/fps to a local VMS or NAS box.
Retrieving the images can be done from either source, using any PC browser or non-Windows mobile device (think iPad, iPhone, Blackberry). Storage is provided by one of many Axis Hosting Providers (we like Brivo, since they are already in the business of providing SaaS-based security solutions).
We will be supplying this solution as a service to companies who want cameras but do not want an in-house server. Also, to those companies who might want an alternative recording solution for failsafe IPVS recording!
