Dru Clark said: Sorry for the delayed response. I do believe our security system is monitored through it... We have internet at our shop through Verizon which is Wireless.
It cost us around $50 for the module to go cellular with our security system and about $2 more per month to monitor it that way. but telephone was costing us about $50 per month so it was a good savings. a plus is that with cellular I can not get text on my phone about arm and disarm times as well as when the alarm is set off.
