Jail Design Guide - Notes

Chapter 8: Security Perimeter

  • Goal: prevent escape and contraband passage

Ingredients of Security

  • Denial (aka prevention): Restrict inmate access to unauthorized internal areas or the outside; provide physical separation for various inmate classifications; control inmate movement using sallyports, staff supervision; eliminate contraband passage with a secure perimeter
  • Detection: regular inmate counts, random cell counts, searches, guard notices inmate climbing wall, etc
  • Response: triggering lights, lighting selected area, closing gates, etc
  • Assessment: determining the nature, degree of a situation

Design focus

  • Creating an overall, 3d barrier called a security perimeter
    • Prevents contraband from coming in
    • Prevents unauthorized people from coming in or leaving
    • This is 3d. Inside is our "security envelope".
  • Internal security zones
    • Control internal movement
    • Maintain separation between key activities, inmate occupied areas, especially inmates who pose the highest risk
  • Master control (see ch 13)
    • Be able to monitor all security systems (cctv, alarms, motion detectors, etc)
    • Communicate with, control and monitor, and observe people at all egress/ingress points in the main security envelope
    • Communicate with, control and monitor, and observe people at internal security zones. And be able to inhibit their movement
    • Communicate with facility staff, wherever they are in the facility
    • Control entry into the master control space
    • Facilitate efficient staff and inmate movement throughout the facility
