Abstract: Network appliances for use in combination with a network based full service, multi-media surveillance system provide a wide range of monitoring techniques utilizing digital network architecture. The appliances may be connected to the surveillance system for transmitting event data, video and/or image monitoring information, audio signals and other data over significant distances using digital data transmission over networks such as a local area network (LAN), a wireless LAN (WLAN), a wide area network such as the Internet for other networks, permitting remote manual and/or automatic assessment and response. The wireless LAN connectivity permits local distribution of sensor information audio, video and image data with relatively high bandwidth without requirement of a license and without relying on a common carrier and the fees associated therewith.
