Physical security requirements

uting to the problem are diverse. size of the building, anonymity inside the precincts of the building, contents of the building, characteristics of occupants, location and physical features.
Every door in a tall building is supposed to have a working lock at all times for security of those using the different rooms. The doors and windows are supposed to be reinforced, fitted with intrusion alarms to whine away when someone intrudes in. lighting must be feasible at all times with a back-up generator in place just in case there is a power outage. Perimeters gates, fences and bollards are supposed to be erected all round to prevent unnecessary access by intruders. Physical security hardens a building and makes it inaccessible to the unwanted publics. Some offenders however see increased security as a threat to their ingenuity (Cofer, 2013).
CCTV is a primary part of security of any building. Internet based CCTV can also be installed so that all security concerns about the building can be monitored elsewhere. This means that one does not have to be in the building to view the security concerns in it. It should however be noted that CCTV is quite open and seen and therefore interferes with the open offences that would have taken place. Once this is known, there is always a counter plan by the offenders. These should be erected in all possible places. the elevators, lobbies and along adjacent sidewalks.
Three concepts address the aspect of physical design. Physical design determines the design of physical security. The first is creation of ‘defensible space’. Challinger (2008) stipulated that crime rate with reference to buildings increased as the number of floors increased.
Situational crime prevention is also a fact under design of the building. A modification of environmental factors has to be made to reduce crime in the building. In the case of CPTED, all the workers in the building will be required to be aware of their situations and be responsible for
