Ever wonder what goes on in your house while you're away? (Here's a hint: your cat sleeps 23 hours a day.) Keep tabs on the home front with Avaak's Vue Personal Video Network, a set of two small, wireless, battery-operated cameras that you can position anywhere in your house. The cameras feed live streaming video to a private website accessible via the Internet or a Flash-enabled mobile device, so you can check on your kids, your pets or that leak in the ceiling anytime. Just set up the cameras and plug a box into your router, and that's it. No software installation required. It's no substitute for being home, but it might lessen the pain of spending another night in a roadside Days Inn.
