Duo Portable Security Sensor

It doesn't matter what you're trying to protect or where it is, the Duo Portable Security Sensor can offer added peace of mind. This palm-sized gadget uses light and motion sensors to detect disturbances and a dedicated cellular connection send you alerts via SMS. As a result, it doesn't need a Wifi connection, and with up to a year of battery life, it doesn't need an outlet, either — making it ideal for places like your safe at home or your luggage at a hotel.
