For valuables that you can’t hide or lock up, such as a flat-screen TV, stereo system, and computers, make sure they’re insured through your homeowner’s or renter’s insurance. Unless you invest in a home security system (and sometimes even if you do), it’s not possible to protect every item in your home. But you can take precautions to password-protect and GPS-activate laptops and smartphones so that their recovery is more likely, should they be stolen.
