One potential use for the home computer is as a monitoring device, whether it be to check in on a child in another room or to keep an eye out for potential intruders into the home. ZoneMinder 1.21.2 allows visitors to do just that, and also to capture various images recorded with the use of one or more cameras attached to their computer. Users can also choose to be notified by email when the camera records any new images, if they so desire. The website for ZoneMinder also includes a FAQ section, along with various screenshots. Zoneminder is compatible with the Linux operating system.
