Nowadays major burglar alarms provide a dial-out function so owners of the premised guarded can be informed by phone call whenever there is alarm triggered. In occasions, there is no landline available in remote areas. Even the provider is willing to extend their last miles to where you want, it is definitely not available immediately. You have to wait and you have to paid.
An out-of-box solution is making use of GSM mobile networks. Now comes in market a kind of GSM dialer that can integrate with burglar alarm that has dial-out capability. The setup is straight forward that, instead of plugging the telephone cord to wall socket, you plug the cord to the dialer. When alarm triggered, it instructs the GSM dialer to dial out.
Of course, for places where mobile network is also not available, this unit is still useless and the dial-out notification feature of burglar alarm still useless.
