okay I am hoping to travel in the next year or two and am wanting to do something of a video blog, now I was hoping to have a sort of concealed camera in my jacket or shirt, something which doesnt scream steal me and also something that will continue recording for 12 hours continuously so as to ensure that I dont miss anything. preferably I would like it to record on sd cards and have a pc freindly format eg mkv avi etc .
any thoughts?
