How to organize the "Panic button" service?

Question

Distributed Computing

Good afternoon,
you need to create a system with the following functionality: the user presses one single button (initially at home, but it would be great if the system was wearable), the pressing signal comes to the control room, where the operator sees the device number (and hence all the parameters - then who owns it). The operator is already working.
There is an understanding of what can be done on the basis of any security system with a gsm channel. Question: what is better to choose, how to receive a signal, how to understand from whom it is and display it in the program.
What other options are there for organizing the system? Grandmotherphones? Tablets? Something else? The most exotic ideas are accepted.
Thanks to.

Answer 1

There are GSM alarms that can be equipped with panic buttons. The bottom line is this - when the button is triggered, an SMS message leaves. Next, you need to either just get it, or create a handler that will collect and analyze them.

Answer 2

Look for information on this project Life button
Where did you publish an article about technical implementation and problems
