Time-lapse over a long period

Hello All,

A client wants to do a time-lapse video of the INT. of a warehouse being constructed over about a month. I'm wondering if anyone can recommend a camera that can handle low lighting situations and run for about a week without requiring battery/card changes. The warehouse is in another state, and I'll only be able to drop in once a week to swap cards and batteries.

I did a test shoot with a Brinno camera, but wasn't very happy with the results. I looked into the Brinno Pro, but am wondering what other options there are?

Thank you!

As to battery, what about running it from a deep-cycle marine (car) battery?
