What is Zummer-GSM and how does it work?
Zummer-GSM is a new state-of-the-art wireless intruder alarm which also incorporates remote listening facilities. These facilities are designed for remote listening and monitoring premises and PSTN phone lines. Alarm and flood sensors, phone line adapter and a microphone are connected to Zummer-GSM to ensure the systems functionality. As soon as one of the sensor goes off or the controlled phone line activates, Zummer-GSM informs you in an instant by an SMS-message and/or direct phone call. By placing a call to Zummer-GSM, you can listen to all conversations around in the premise or over the phone line installed in the premise. Being able to listen to what is going on in the secured area helps you simply recognize if the alarm is true or false. Find out more about Zummer-GSM.
