systems are able to analyse huge amounts
of data, which of course is advantageous
when you have to review hours of
surveillance images.
By ‘learning’ how the observed object
moves, how tall or small it is, whether it
has two arms and two legs and how fast
it is going, the AI application ranks the
information and decides whether it is
probable that the object is human. This kind
of functionality is common in the field of
safety and security today.
Artificial Intelligence, Machine
Learning and Deep Learning
AI is the act of simulating an intellectual
task. An essential component of AI is ML
and sometimes the two expressions are used
interchangeably. AI uses algorithms to go

through data, learn from it, and then make
predictions. However, to mimic the complex
human brain, a computer needs lots of
training. So-called Deep Learning (DL) is an
advanced way of implementing ML, but it
requires lots of data, advanced classifications
and several layers of analysis to produce
‘deeper’ knowledge.
A compute-intensive model, DL is today
mostly run on servers with multiple GPU
processors, but when edge devices increase
their computing capacity, some applications
will probably move there in the future.
AI in surveillance – design with
a purpose
Understanding the primary purpose of the
system and how the footage eventually
might be used is essential.
Image usability can only be achieved if the
system has been adapted to the specific
conditions of the environment and is
properly maintained. To succeed the primary
focus therefore can’t be on the technology,
but on the solution of a particular use case.
Only as part of a complete and well-
designed solution, where human expertise
has taken all kinds of considerations into
account, can AI offer great opportunities
within surveillance.
AI in surveillance – advantages
A surveillance solution – with or without
AI – is rarely an off-the-shelf solution since
every business and use case is unique.
Whenever there is a need to process and
analyse huge amounts of data, computers
