Just having an alarm system isn't always enough, so it's a good idea to ensure that the equipment you have and the layout of each device will allow for maximum efficacy. This begins with understanding the nature of each device so that you can fine tune their placement and their internal settings. That said, unless you're a certified security technician, it's in your best interests to call in a professional to actually make these changes.
Coverage and Visibility
The most effective security systems are those which are prominently displayed, but can't be reached without triggering a sensor or alarm. A good example would be interior cameras, which should be positioned in such a way that they can capture as many entry points as possible. In some homes, this may require more than one camera, but in this scenario it's a good idea to make sure that each camera can see at least one other camera.
To turn things like cameras and motion detectors to evidence gathering devices and scare tactics, make sure they can be seen from potential entry points. If a thief can see a motion detector or glass-break sensor from the window, he'll be less likely to attempt to breach at that point. For an added deterrent, make sure to arm other windows with magnetic alarm triggers.
Denial of Opportunities
Thieves are at their most effective when they can operate unseen, or can masquerade as somebody they aren't. If you deny them these opportunities, they tend to quickly lose interest, and there are some simple additions you can make to your security system to that end. Motion activated exterior lights are a good start, but these should be elevated as high as possible, covering each entrance and any potential hiding places.
Cover your front door with a high resolution exterior camera, so that anyone approaching it has their face caught on film. Not only will this help you keep tabs on who is arriving at your home, but it will deter thieves from attempting to scout your home initially, since there will be an existing link between them and your house before they even set foot inside.
Be aware that, regardless of how detailed the plans for your security system, your best defense against a break-in is vigilance. Know your neighbors, make sure they know you, and build on that relationship often. It's always beneficial to have more eyes watching over your home, whether living or electronic.
