"Internet of things" home camera companies that sell cameras for monitoring your children that require that the video feed be streamed to their servers.

The security implications of this are ridiculous. Remember how people complained about the Kinect putting a camera in your living room? At least that one would require your xbox to be taken over for somebody to spy on you. These cameras constantly upload videos of your household by design. And a quick google search for "camera vulnerability" shows how insecure these things are.

Most of the top amazon results are for this sort of camera, but you can easily get a camera that can stream to your PC or qnap/synology NAS instead. If it's streaming to your LAN only, it doesn't open up so many ludicrous security vulnerabilities. If you set up a home VPN, you can get the same remote access features without paying for their "cloud recording" services.
