Hi everyone,

I'm writing from the states and looking to put together a wired system for a commercial storefront business that I could use one of the self monitoring GSM SIM cards sold on Amazon, could anyone here please throw some suggestions my way? I did a little looking around the forum and noticed the Bosch system frequently talked about that looks very well built but haven't installed a system in a number of years, I'm aware of the wireless setups but wish to avoid worrying about dead battery replacements & such.

Cheers
