Watchdog is Puppy Linux 2.16 with zoneminder installed. Watchdog runs from CD, and is blisteringly fast. Watchdog can also be installed to HDD, DVD, Flash drive, basically virtually any PC media capable of booting, but no installation is required. It is also very easy to configure the system the way you want (Eg configure your cameras) then to create a new Cd for just your machine, all your settings will be carried over. Works well with USB cameras; perfect for any scale surveillance with many modes of recording including motion detection. Created by Hushpuppy and supprted on Zoneminder and Puppy linux forums
