How do you know if your home is an easy aim for thefts? Around the holidays, many families don’t consider taking proper measures to prevent their homes from suffering holiday thefts. With just a few simple steps, you can better make sure of the safety of your home during all of the holiday celebrations. Here are a few tips for making it difficult to tell you are away from home.

●Either have a trusted neighbor pick up your mail and newspapers, or tell your mailperson to hold your mail until you return. Nothing says “Hey, we are not home!” like when your postbox is filled with all kinds of mails and you have many different newspapers in your driveway.

● Set several different lights in your house on random timers（随机定时器）. Don't leave your outdoor lights on all the time. Instead, put your outside light on timers to be on during the nights. If an outdoor light remains on for days at a time, it means that nobody is home to turn it off.

● If you have pets that you are not taking with you on vacation, leave them with friend, rather than having someone come into your house every day to take care of them. When thefts see a neighbor or friend entering your house every day, they will know you are not home.

● Close all your curtains when you leave town. This is effective to deter possible thefts, as no one can see what is in your house. If they don't know what there is to take, then the risk is even greater for them to break in.

This article just has suggested a few tips to help you keep your house safe on holiday. Nothing can truly protect your home unless you have it monitored by a professional home security system.
