Looking at updating my scantronic alarm to a smarter model and this seems to be a common diy choice. I have done some reading and have the below questions.

 

1) To enable communication for the app control and alerts I will need a communication module. If I wanted a backup for WiFi (broadband) failing could I just install the gprs module and use a SIM card for app alerts and sms alerts or would I need both modules?

2) Do the modules fit in both panel cases the small/large or do I need the large one?

 

Thanks

 

Unless I'm mistaken....

 

You can either have a lan card

A wireless card

or card which sends Texts

 

& only 1 fitted to the system ? (inside the metal case)

Oh yes , I forgot about the title lol

So only one connectivity card can be installed? I guess I best stick with the WiFi one unless the gprs one can do everything? Obviously will need a SIM card but more robust.
