James Bond-Style Security

Thanks to Lazer Trip Wire, you too can have affordable, James Bond-style security. For just under $25, you get three mountable units that can each transmit an infrared beam which sounds an alarm whenever it's broken. Although a cautious sleuth might be able to avoid a couple of beams, three or more units can be used to form a pretty secure barrier that even the world limbo champion couldn't get through unscathed. Even with one or two units, however, the element of surprise can go a long way, so don't go out advertising -- let perpetrators find out the hard way.

In addition to saving your DIY project lab from evil henchmen and protecting your assets when you catch some snooze, these gadgets can also produce some good laughs if you use them to catch people snooping on you or rummaging through your stuff when they shouldn't be.
