Yup, amazing... I've got several of those scattered around the house to keep an eye on the kiddos. It's pretty cool, I can look in, including at night (These $35 web cams not only can move around, they've not night vision too!) on 'em from anywhere in the world from a computer or a phone or tablet...
(And yeah, it's been secured... Don't want EVERYONE looking in!)
I have an old one I got on Amazon for $350... $35 sounds ten times better

...
Mine hooks to the house wireless network and has an internal web server
you connect to with a browser to configure it. It can be configured to do a lot of
stuff, I configured it to be motion triggered and send pictures via email to
my gmail account. Do these $35 ones have all that?
I only have mine hooked up when I'm gone. So far the only pictures are of the
lady who feeds the cats, and the yellow cat on the counter...
