I am not home much, but would like to be able to record what goes on outside my home when I am not there. I did have an outside camera attached to a VCR recorder and it would tape up to 6 hours, but that recorder broke. If at all possable, I would like to be able to plug it into my computer and record onto a disk. Also, I would like to record as much as possable. If it is possable, what would be the longest I could record?
