The application of security measures is tailored to the needs and requirements of the facility to be secured. The security method adopted will be influenced by the type of facility or material to be protected, the nature of the environment and the client’s previous security experience and any perceived threat. There are many factors which need to be considered when planning a security system: the nature and time schedules of activities in and around the site or facility, the physical structure of the facility/complex to be secured, the surrounding natural and human environment, fluctuations and variations in the weather and the combination with new or proven technologies.
