:* Security needs to be considered for each location and can vary depending on surroundings and potential threat level.  

:* Transit, port, and aviation may have greater concerns with homeland security depending on use of the maintenance building. Conduct threat and vulnerability assessments based on applicable requirements. 

:* Access control and closed circuit television (CCTV) systems are costly, require extensive maintenance, large volumes of data storage and should only be applied as required on both the inside and outside of the facility.  

:* Remote facilities may not have IT access available and the cost of extending IT availability may not be practical.  In these instances, use the most cost effective technology such as wireless.

:* Exterior cameras shall be focused upon entrances to the facility to observe personnel entering and exiting the building.  One camera may be used to monitor multiple entrances if the resultant resolution is adequate to distinguish general identity features including apparel, height, build and race.  Camera resolution shall not be suitable for facial recognition unless justified by a threat and vulnerability assessment (TVA).  Exterior cameras shall not be used for perimeter detection or parking lot surveillance unless justified by a TVA.

:* Interior cameras shall be used only to monitor interior features having high security concerns (justified by missing high cost, easily portable inventory investigations) such as material or tool storage rooms or rooms having a retail component.  Interior cameras shall not be used solely to monitor employees.  Future consideration could be given to interior cameras to assist police during an active shooter event; however, this is not a current design element.

:* Access control card readers shall be used on entrances to the building and only on doors leading to rooms having high security concerns such as material or tool storage rooms or rooms having a retail component. 

:* Generally fencing should be provided at the perimeter of the facility with limited entrance/egress gates.  Gates should balance security with efficient flow.
