Dropcam is an internet-based video camera that can be used for security or for fun. It has both day and nighttime modes, although the nighttime mode only works indoors. If you try to film something outside, the infrared night light reflect off the window making the image a screen of white.
While I have used it mainly to film the dog, outdoor wildlife and view outside work being done while I was away, it is a fun and useful took and worth the $10 a month for the 7-day recording window. Videos can be edited and downloaded for future showing. Another fun feature is the time-lapse, which I used to create the video below. It compressed an hour of raking leaves into 60 seconds.
