firstly I'm really not sure if it was such a great idea to put that link up!! still nice to have a look at your hallway etc etc :)
May not be an ideal solution to your problem, but if in IE7 you go to the tools menu and then manage add-ons and then select find add-ons then do a search for refresher there is an add-on that enables you to set IE to automatically refresh a web page at a desired interval.
the other thing you could try is in IE goto tools menu, select internet options and then select security on the tabs at the top. On this page if you click on trusted sites and then the sites button just below, add the above as a trusted site (you will have to take the tick out off requires server verification)
once you have done that click close and then click on the custom level button at the bottom and go down the list and enable everything. this will let IE run any thing from you camera site that the normal security levels my be blocking.
This will only effect the security level on your site, no others so should not cause any security issues elsewhere
