physical protection system, security barrier, perimeter protection, burglary, delay time


Perimeter security defines the private space from the public space and also serves as the first barrier between the intruder and the protected interest. Delay time is one of the input parameters used in a quantitative approach to the design of a physical protection system. The objective of the physical protection system is to delay the intruder long enough for the law enforcement to arrive on the scene and apprehend the intruder. Perimeter protection is located in the exterior and is affected by various factors such as ambient temperature. In cold temperatures, the technical parameters deteriorate and the delay time for penetration into the protected object decreases. The paper points out that the delay time is longest at 0 °C and that the delay time decreases as the ambient temperature increases. A further perspective is mentioned on the adaptation of the tests and increasing the degree of subjectivity of the test results.
