My Tip, No Alarm.
I’ve never figured that it is worthwhile for most people to shell out for an alarm system. An alarm cannot stop some crook from breaking into your home.
Far better I say to invest in hardening up your home. Good locks, strong doors, strong windows.
If you are at home and someone starts to break in I think it very likely you are going to wake. Pick up your phone and call the police or someone for help. You don’t need an alarm to do that. Oh yeah, if you leave a window open then the burglar could come into your home without you hearing a thing, so don’t go leaving windows open.
If you are not at home when a burglar wants to rob you, what good is an alarm going to do you? By the time the police get to your home those bad boys will be long, long gone.
Harden your home and noone will get in without making noise so that neighbors hear. Perhaps maybe if you live right out somewhere remote and there is no neighbors then an alarm that contacts the police is a deal. But then if you are that far out the police are not going to arrive in time to stop the burglars.
I have hardened my home as much as I can, best locks on doors that you will not kick in and double pane windows (tougher to break) that also have good locks. I feel far more secure than I would if I had an alarm.
