A self-contained digital video recorder (DVR) surveillance system offering real time recording for up to four locally connected analog cameras simultaneously. Attached directly to computer IP networks, it provides convenient access to live and recorded video using a standard web browser. Unique APViS technology extends the storage life for prioritized digital images on internal hard disk memory, while maintaining the high quality of imaging data. Used as a standalone unit, or an autonomous component within a larger globally distributed video recording system, the unit is ideal for use within large retail chains, franchise operations, or any business requiring unmanned visual security.
