Here is an alarm system that helps you protect your valuable items more conveniently. The CoinGuard system is a motion detection device that sends an alert to your smartphone when your valuable items are touched. It consists of a coin-sized wireless sensor, a personal beacon, and a gateway to link to your home network. The sensor detects movement and vibrations and alerts you on your smartphone.
The iHomeware Beacon is a small device that you can carry with you when you leave your home. That lets the system know you are not around, so it can automatically arm or disarm itself. The CoinGuard system lets you back under $100 at this time.
