Schlage has an interesting product. Once you download the software to your device, Schlage will notify you of anyone entering your house. Once someone is home, Schlage will send you a message, alerting you of this. As the above video describes, this is great if you have a family with degenerate teenagers. Schlage is now offering a contest where you can win a BlackBerry Storm and a Schlage LiNK system for your home.
