Meet the iHomeware CoinGuard system: a vibration alarm system that helps you protect your valuable items. CoinGuard has a coin-sized wireless sensor that detects motion and sends an alert to your smartphone when your valuable items are touched. There is also a personal beacon to automatically arm or disarm your security system.
The system consists of a gateway that serves as the link between your WiFi network and wireless sensors. The companion smartphone app lets you control your vibration alarm system more easily. The above video shows how the CoinGuard alarm system works.[Source]
