When thinking about having a security system installed there are 6 aspects to consider. I will be listing each and discussing the values of each in the next few weeks.
Basically they are: (1) yard signs & window/door decals, (2) perimeter window & door contacts, (3) interior protection devices, (4) fire protection,(5) carbon monoxide detectors, (6) special partitions.
The yard signs & window decals are very important. It lets a would be thief know you are protected by an alarm system. A burglar does not want to encounter an alarm system because first it limits the time he has to steal from you and there is a good possibility he will get caught.
Would you break into a house with an alarm system when your neighbor does not have one??? Which one would you burglarize??? Place your signs & decals on all sides of the house so your home cannot be approached by someone and not know you have an alarm system.
