A whole bunch of companies are getting together to make everywhere a safer place including one company called InGrid that is harnessing the power of the web to get it done… 

The company’s technology is based on wireless sensors placed at many points inside a home that are linked to both a handheld device and a password-protected Web site.

The sensors provide real-time information not only on whether the house is safe from burglars, but whether children, parents or babysitters have entered the premises using their passcodes.
