Here is a smart alarm that uses a SIM card to connect with you anywhere. The smanos X330 sounds a siren and sends you a SMS text or phone call when intrusion is detected. You can install the sensor on your entrance door to catch any intrusion attempts. In the Delay zone, the sensor will not sound an alarm until the specified grace period is passed.
The X330 is compatible with iOS and Android devices. Pre-authorized users can arm or disarm the system through the free app. A backup battery of 1200 mAh is also available.
