OK, so you knew when you took the job that you'd spend a zillion hours on the road, but you find yourself pining for home and hearth more than you expected. With X-10's XRay Vision Video Camera Kit (just $129), you can keep tabs on your home, your family, your pets, and anybody who visits them. The kit includes a tiny wireless color camera that can be set up to take snapshots at specified intervals and automatically post them to a password-protected Web page that the company hosts for you. The camera also can e-mail pictures to your PC. You just dial in, and the Xray Vision software will recognize your distinctive ring (which you specify) and then dial into your Internet Service Provider and start taking pictures. You can even change the camera settings remotely.
