Hardware Pacers has an exceptionally detailed (albeit slightly fanboy-sounding) review of Actiontec's 54Mbps Wireless Network Camera, including a full rundown of the install process and loads of screenshots. Their overall impression was that the camera worked perfectly—it was simple access from a web browser and the video stream was great, at least at the 320x240 resolution. They noticed what they termed a dramatic slowdown when bumped up to 640x480, so it effectively becomes a question of exactly how much detail you want in your voyeuristic indulgences. Regardless, it's a small, easily mounted camera with a built-in microphone and email-capable motion detector for just about $200. Not too bad a deal.
