I'm looking to install a wireless alarm system with GSM dialer and PIR/motion detectors. There are a lot of brands and systems on the market, and I have no idea of the benefits and drawbacks of the various systems. I want to have it so that the GSM backup will call me, and a couple of other people/monitoring service. Apparently, some GSM units will send only text messages and emails. Anyway, prime contender brands are Ademco / Honeywell GE Security (GSM email only I think - not good siren connection either) DSC Visonic (made in Israel) Prices are comparable Trying to get info from the GE website is a nightmare. Visonic have a good site. Not sure if this is a reflection of the quality of the company and/or their products. Not tried the other manufacturer's websites yet. If anyone can offer opinions on reliability and utility etc I would be grateful.
