Many burglars call a house before they break in.
If you answering machine has many messages, and the caller can detect it, it is a giveaway that you haven't been home for awhile. Install outdoor motion detector lights.

If your neighbors know that there are motion detectors, they will pay especially close attention if they see the lights on. Lastly, leave a phone number where you can be found in an emergency.
