D-Link DCS-900W Internet Camera $148.99
For home security, baby monitoring, or simply capturing video in places you don't want to run wire, this wireless camera from D-Link is an affordable tool with a strangely 70's sci-fi appeal. The barrel shape and mounting base look like this camera was designed for sterile office installation, with enough quirk to make you find it almost cute (did I just say that?) Instead of Ethernet, the camera connects to any network via 802.11b, making it possible to put these things almost anywhere. Stream video to the Web, archive data to your hard drive, or email clips to an inbox destination of your choosing. There's a Web server on board, with remote access available to any device with a Java-enabled Web browser.
