A great, feature-packed camera and good HTTP web console, although it depends on an ActiveX control so is only fully functional in Internet Explorer (you don't get sound and some controls are missing in Chrome).
To be clear, "motion detection" is not motion tracking, it just means it detects movement in the place where its looking and can begin recording, or send a snapshot.
Good clear video stream, good microphone, too. MJPEG, .asf and RTSP streams. Lots of people using them so there's good support in forums.
Would like night-vision - not tested it, but people report that it has an IR filter so even with your own lamp, you won't see anything.
Using ours as a baby monitor. iPhone and WP7 apps available.
