Before considering an alarm system, insure that your home is target hardened. Target hardened means you have checked your homes locks, lighting, landscape, and have a solid crime prevention strategy. If you are unsure, you can call 414-228-1741 and he will come out to your home and conduct a security survey for no cost to you. After your home has been target hardened and you still want an alarm system as another blanket of security there are many licensed alarm companies in the greater Milwaukee area. We recommend that alarm buyers get at least two bids for the work, ask for references, and make training provided to everyone who will use the alarm.
