Can I use a Airport Express and a Foscam IP camera without a internet connection?

Question

Hi All,
I have a Foscam FI8918W IP camera.  I have it working perfectly at home on my local network over wifi with either my Airport Extreme or my Airport Express.
I planned to use this IP cam as a wireless camera for on stage work with bands, monitoring equipment that I can't see during the show utilising the Airport Express, my MBP or iPad.
As I have said, i have everything working very well, until I disconnect the Airport Express from the mains power and remove the CAT5 cable from my modem to the A.E.  When I reconnect the power (but not the internet connection), I get error messages from the IP camera software that the Subnet mask settings are incorrect.
I cannot get the camera to work until I reconnect the internet connection.  After a few moments, the issue's are resolved and everything starts working again and I can view the camera's video feed from an i.p. address.
Question is: Is there a way to set up the A.E. so that it doesn't require a internet connection?
I will not have internet at a lot of venues and need to get this to work just as a stand alone setup.
Thanks in advance!

I'm not sure I quite understand. Do you wish to use the AEX to provide a wireless connection for a device that has an Ethernet port but no wireless capability of its own? You wish to use it in place of a wireless card that isn't internally installed? If so, the answer is, "Yes." It will work as a wireless access point. But you must have an extant wireless network because the AEX won't have an Internet connection when used in this way.
If you have an existing wireless network with a wireless router connected to your cable/DSL model or your modem is a wireless router as well, then the AEX may connect to it in bridge mode. Note that AEXs don't always play nice with non-Apple routers. Some work; others don't.
