In-home security cameras that can monitor pets and/or children have been around for years, but if the pet (or child) moves from the field of view for the camera, it becomes pretty useless.
From DigInfo News out of Japan, here's a video report on a new automatic motion-tracking camera that can follow the animal around, with additional features like temperature and noise monitoring, as well as an alert that get sent via text message when the dog (or child or senior citizen) doesn't move for three hours.
I think this device would be useful for homeowners with younger pets in their home - but I'm pretty sure that my 10-year-old dog doesn't really move much inside the house when we're not there. Every time I see her, she's on our couch sleeping.
