At AAT(Advanced Alarm Technology) we believe the best security is security you don't have to worry about. That is, security that is in place and constantly on alert. In the last couple of decades the combination of socio-economic changes that have taken place confirms that issues of security are at the heart of American's all across the nation. There are many reasons for this but primarily economic restructuring, unemployment and certainly drugs, are fundamental. America's perception of security is an apprehension that society is becoming less secure – that the streets are less safe, our homes more vulnerable: that crime and violence in our personal lives threaten personal and physical safety. In essence, Americans are deeply concerned about crime and violence, specifically about the volume and type of crime that takes place in their communities and at the workplace. At Advanced Alarm Technology we separate personal threat to physical safety into two parts: one focusing on the threat of violent crime to personal safety while the other concentrates on property crime. Either can be separate or, can occur in the same crime activity.
