Is it possible to use a GSM module for security system communications without subscribing to a monthly service? I'm looking into this as a redundant path in case the internet connection is unavailable.
I've unsuccessfully searched for information, but may not be using the right key words.
What is required on the backend for GSM to work without paying a monitoring company? I have a server in a data center; may be possible to host a service on there to handle the comms?
Thanks!
