Help Me Choose A Camera For A Store

I'm looking at buying a fix camera for IP surveillance and I'm having a hard time deciding what to go for. I read the various articles available but still can't get a clear answer. Here are the things I need to take into account:

• Fix camera.
• Camera will cover a store front about 30' wide.
• Camera will be between 150' and 250' from the scene.
• Camera should be able to take pictures for identification purposes.
• Moderate movements in the zone.
• Should display good performances in low lighting conditions.
• Bandwidth/Storage is a concern.
• Budget is not a major concern.

I don't want to take too much of your time so there's no need to justify your recommendation in great details, but your suggestions would be appreciated.
