Going away for the holidays? Your home is particularly vulnerable to a break-in. Burglars watch for vacancy signs: accumulating stacks of mail, piles of unretrieved newspapers, and steady-burning or always-off entry lights. You can monitor your home remotely thanks to network cameras like this one. This model allows you to access a live stream of your home on the internet, and the system can be programmed to send an e-mail alert anytime it detects motion. Like many new security products, smartphone apps are available for alerts, too. With built-in recording functionality, if something does happen, you'll have it all on tape.
