The new BBAirPurifier is just the item you need if you're looking for a covert nanny cam. It may look like your every day air purifier (and with its two speed ionizer you can be sure it will help clean up your air) but it actually has a built in camera. Its purifier features all work just as you would expect, the camera system having no impact on the replaceable fiilters, but this little purifier has the support for 8GB or 16GB internal memory and sports full color VGA quality video and full motion detection.
