I'm interested in making my own home CCTV system using Ubuntu. I want to get network cameras similar to this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260745150596
I want a way to dump or record the live stream to a large hard drive, but have Ubuntu automatically delete the oldest parts of the video while the drive fills, so it can continue recording new data continuously.
How can this auto-delete while recording be accomplished? I've searched and searched.
