No hard feelings at all here. From what I have gathered so far alarm install all require the same thing(as far as connections). A good installer can make a cheap alarm work pretty good. But its only going to work as good as its features. Some things that take into account: sensitivity adjustment, sensor placements, alarm programming. Any info about code alarms that I mentioned before was from the installer I work with. He is very good and been doing it for 15 years or more. Maybe he is a little out of date but not by that much.
