Layered Security And Security Cameras
We can trace physical security as far back as the ancient times. Years ago there were no retail security systems to protect gold and riches then and there were no access control equipment to automatically lift drawbridges of castles then but there were moats to protect castles from surprise attacks from enemies. While the first thing that comes to mind when talking about security systems is the use of security cameras, they are actually the last tier to a good physical security system.
The main goal of physical security system is to deter potential attackers from carrying out the deed. A good physical security system has four tiers, namely, environmental design, access control, intrusion detection and identification, aimed to protect structures from damage or intrusion, to dishearten attackers by creating obstacles, to make it apparent that any kind of attack will likely be detected by a security force and different kinds of security equipment such as burglar alarms and CCTV security cameras and to finally detect the criminals.
