Linksys has added a fairly advanced wireless camera to its line-up: The remotely controllable WVC200 can have its own IP address and supports dynamic DNS. It has pan, tilt, and 2x zoom features, and uses Wi-Fi to stream 640 by 480 video with MPEG4. The device can be configured to start pushing video and audio to an optional hard drive when it detects motion, while also sending an alert via email or text messaging, including a video clip. An LCD display makes it easier to configure multiple units. A software package allows remote monitoring of up to nine of these devices.
The name of this camera, by the way? The Linksys Wireless-G Pan/Tilt/Zoom (PTZ) Internet Camera with Audio. Whew. A cool $299 list.
