For $300 you can build a remote controlled surveillance system to monitor your home via the internet.
Cell phones and PDAs are also supported by the new plug-and-play Panasonic BL-C131A pan/tilt wireless network camera. With the built-in motion detector and microphone, the camera can be set to notify you by email when someone enters your home. The 1 Lux CMOS sensor enables good image quality and 30 frames per sec MPEG-4 video even in low light conditions. Although D-Link, Linksys and others also offer similar devices the features of the Panasonic Network Camera Wireless 802.11 justifies its positive reviews on Amazon.com.
Remote home surveillance is yet another useful home automation application that is possible thanks to the wireless broadband internet!
