So I have a fancy old muscle car that I have put a ton of work and would like to hook up an ip camera. I want it so that when the car is parked, I can monitor and record what is going on with it. I was planning on getting an ip camera with a portable hotspot device such as the mifi. I was wondering if anyone knew how much data one would use because I would like to attach it to my account which has 4gb of data. would that be enough to run one if I am not constantly streaming the video to somewhere?
