rob walton Posted November 28, 2006 Share Posted November 28, 2006 Hi Guys, I wish to put a temporary (6 months) alarm on a small outbuilding and scaffold. I am lead to believe that beam detectors are the way to go, but want some monitoring as well. I could install a phone line but possibly easy to cut, so i'm thinking of a GSM Dialler. Please could anyone advise me about contract or lease terms of such devices, is pay as you go possible? I've never used such devices so any advise would be greatly appreciated, also any other pitfalls i should be aware of. Link to comment Share on other sites More sharing options...
Guest Posted November 28, 2006 Share Posted November 28, 2006 GSM is fine, as is PAYG. Twin beams are what i would use, to prevent false alarms from birds ect. Link to comment Share on other sites More sharing options...
