There are no federal regulations governing how video systems are designed.
Regulations implemented at the state or municipal levels focus on how operational elements of surveillance
can be performed, rather than whether a person must give his/her consent to such surveillance, who can
access recorded video, what controls and restrictions apply to the dissemination of recorded video, etc.
These issues may impact the design of a surveillance system for public areas in a city, but generally do not
apply to an airport environment where security is recognized by all stakeholders, including the traveling
public, as essential functions of the airport.
Video surveillance technology, like most of the technology discussed in this Standard, is expected to
continue to improve. Most of the improvements will be incremental, rather than revolutionary, but they will
significantly impact how operational requirements and technical requirements are specified, and the
potential for flexibility and expansion.
Technical improvements that are likely to impact video systems include:
Better megapixel (MP) cameras: MP cameras already have about half of the security camera
market. Their weaknesses, including limited wide dynamic range (WDR) and low light sensitivity,
no longer drive the use of MP cameras due to stead technology improvements. Indeed, for many
designs the baseline minimum camera is now an MP type. That trend will increase, and will
include greater use of multi-imager MP cameras for wide area coverage.
Lower cost uncooled thermal imaging cameras (FLIRs): Price reductions will make thermal
cameras increasingly attractive for exterior video surveillance applications. This market is very
competitive, even with visual imagery cameras, as the result of maturing detector technology and
manufacturing economies of scale.
Exploiting Video Stream Information: Video analytics will continue to improve and are finding
increasing applications. AI technology and its extension, deep learning, are relative new and will
take time to find their best applications. One related application is facial recognition (FR). Where
video cameras are already installed, adding FR for authentication in PACS or for searching stored
video frames is relatively inexpensive. For multi-factor PACS authentication, which is expected
to find wider use, the low cost and ease of implementation of FR make it the biometric of choice.
Vetting camera requirements: TSA §1542 regulations do not mention video cameras, but rather
require the airport to take measures which are “sufficient” for security. While such measures are to
be determined by the airport, other stakeholders also have their own ides of where cameras can
enhance their operations. Examples include DHS Customs and Border Protection (CBP), which
may require complete area and pathway coverage with image quality suitable for forensic purposes;
and airport police who want to use video to cue responders and record events for follow-up actions.
Video feeds are required for Emergency Operations Centers; airport risk management wants
surveillance coverage for liability protection, etc. Early identification of such requirements and
integrating them into the design of video surveillance system is essential.
Innovative displays: Active matrix organic LED (AMOLED) display technology works very well
even in broad daylight, as smartphone manufacturers have proven. The problems of manufacturing
them in larger sizes have held back their use, but other technologies now exist that are competitive.
Less costly video storage: Improvements in technology have made available terabyte drives and
solid state devices (SSDs) at ever decreasing prices. This trend has transformed video storage, and
is expected to continue.
