Enhancing Legacy Systems with Software
It is common for airports to possess legacy systems that don’t yet qualify for replacement, yet they
are challenging to use, whether it is the dated user interface, poor vendor support for updates or
poor integration to other systems whose version are constantly changing.
By integrating these systems, for example an older DVR system, into a PSIM, then the PSIM
becomes both the user interface and the integration hub. This approach extends the useful lifespan
of the legacy system, while increasing its value.
To accomplish this, a legacy system must technically support some kind of Application
Programmer’s Interface (API), so that a PSIM can communicate with it, and the legacy system’s
user is licensed for that interface.
Some vendors are reluctant to release their API because it reduces their ability to protect their
proprietary product. In these cases it may be necessary for the airport to exercise a degree of
pressure to impress the importance on them.
Displaying Information in Command Centers
Security Operations Centers (SOCs) are discussed in Section 7: SOC. There are many ways to configure
operator stations, video monitors, and video walls in a SOC. The challenge is to scale such capabilities for
the particular needs of an airport without overly burdening the SOC operators. Chapter 7 illustrates the wide
diversity of approaches - some provide only for basic operator functions, while others equip multiple
operator stations and provide video walls for group viewing.
Standards exist for the equipment but not for how operator stations should be configured to perform the
specified functions and to reflect operator preferences.
Security lighting increases visibility around perimeters, terminal buildings, fuel storage tanks, cargo areas,
loading docks, as well as in buildings, hallways, and parking lots. It is a security management tool that is
applicable in almost all environments within an airport, and should be considered when airports are
installing and updating other access management sub-systems, particularly those focusing on surveillance.
Security lighting allows the security force to visually monitor the lighted areas, making it difficult for
someone to enter the facility undetected, and facilitating the apprehension of offenders.
There are five general types of security lighting systems:
Continuous Lighting - This is the most commonly used form of security lighting systems, consisting
of a series of fixed light sources arranged to illuminate a given area on a continuous basis with
overlapping cones of light during the hours of darkness.
Standby Lighting - Standby lighting differs from continuous lighting in that only security personnel
or the security system software have control over the system. The arrangement of this lighting
system is similar to continuous lighting and should meet the same security lighting specifications.
When a potential intruder is detected, the security system or guard force can activate the standby
lighting system for extra illumination. It can also be deployed at unattended/attended gates for extra
