Remote property monitoring system using mobile phone text messaging

摘要

A unit allowing remote monitoring of an area via the use of a mobile network SMS system. The unit can be added to an external alarm system or may be used on it own. The unit is triggered by the external alarm system or by one of the internal sensors which include a piezo electric sensor, a panic button, a temperature sensor and a flood water detector. Once triggered an SMS text message containing the location and the cause of the alarm may be sent to one or more mobile phone numbers. The unit can be secured by a four digit alphanumeric number and can be controlled and provide status information remotely. Four auxiliary outputs are provided on the unit for switching external devices.
