Multiple webcam streaming site

Hi there.

I wonder if anyone could provide me with an insight into my options for the following remote monitoring website.

We require a minimum of 10 Cameras for this.
These cameras must be of respectable definition and (ideally) controllable (pan/zoom)
Said cameras will need to be accessed remotely via a website using a secure login for each one. And all of them via an admin page showing all of them at once/seletively.
Ideally it would not embed in SWF format as it would need ot be viewed on iPhones. (I am advised that they hate flash)
The embedded output would need to be versatile enough to accomodate surrounding content. So a bulky app will be problematic.

I would like to get any informaiton regarding software that would provide the abovce funtionality if software is even necessary (have ability to code but not the months it would take to write a robust app)

I would also like to know if anyone has any experience/suggstions for a relatively cheap camera that could provide the above service as we are quite limited in what we can spend on this right now and we need alot.

I truly appreciate any assistance anyone can provide.

Thank you.
