mummyneh Posted June 17, 2008 Share Posted June 17, 2008 Hi, Has anyone heard of the Sentry GSM2 Wireless Autodialler system. I am new to this and was recommened this system. Does anyone have any ideas on whether it is a good system or not. Is it any better then the Scantronic 500r or the Visonic Powermax or is it the same? Any advice would be much appreciated. Thanks Link to comment Share on other sites More sharing options...
Guest RJBsec Posted June 17, 2008 Share Posted June 17, 2008 Don't know the Sentry GSM2 and I suspect that I would if it was a 'professional' system - the Scantronic 500r doesn't have an autodialler or GSM and the Visonic Powermax uses an add-on module for GSM IIRC.
