I have searched online for a GSM home alarm system and Visonic, Yale, Infinite Prime and CommPact seems to be the most popular ones, what are your thoughts and which one you suggest me to purchase?

I have rang two installers today and one said he installs Scantronic alarms and the other one installs Texecom alarms, I believe Scantronic is not as good as Texecom but what are your thoughts?

Is GSM more reliable than using telephone to contact you when alarm is triggered?

Also my house has all the alarm wires fitted when the house was built, should I go for a wired or wireless system?

Thanks
