Surveillance, activation or deactivation of various installations can now be managed from a standard mobile phone using a GSM transmitter.
A GSM transmitter is very professionally built, and it is based on a technology that a receipt is always received for any sent control command (ie a 2-way SMS-based system). Typical areas of application can be such as surveillance of buildings or server room.
We offer a variety of GSM transmitters for data communication based on SMS and GPRS in the standard GMS mobile telephone network.
We have also made a user guide for each of the apps, that shows you how to use the individual app. You can download the manual here:
