I'm in the market for an external USB video camera for my Mac that will allow me to do some time lapse video. I'm looking more so for something of higher quality as apposed to cheap price. I don't want to use the built in camera on my mac as I cannot easily change the direction it is facing. The time lapse videos will be in excess of a 48 hour time span so I need to be sure it is stable. I know that the video camera just takes the pics and its the software that creates the time lapse video. Ideally it would be a camera where mac compatible time lapse software is included. Any suggestions would be greatly appreciated.
