//////////////////////////////////////////////////////////////////// t cht lk beat humans. A well-trained AI can take this to an even higher level of data and image analysis. This functionality can be of practical use in many applications. Safety and security – An AI system can, if properly set up and configured, quickly correlate events detected in several hours of video material from several sources. A surveillance system using AI can trigger a direct alarm, where a potential burglar can be ‘told off’ before the crime has even been committed. Business optimisation and smart cities – Surveillance systems with AI can detect unusual behaviour patterns and use the data to optimise operational efficiency in retail environments or even allow for a controlled flow of traffic and quick responses to incident reports on a highway. www.intelligentcio.com AI in surveillance: Challenges It’s easy to get carried away by the potential of AI in a range of applications, such as improvement of configuration, system optimisation, site design, image configuration and device management. However, there are still fundamental challenges that need to be solved. Human experience beats AI – An AI application can successfully detect a ‘running person’ but, unlike humans who can put the data into context, it cannot know why that person is running – to catch the bus or because he has just robbed the bank. Quality of the data – Without ‘raw material’ in terms of high-quality footage and video, an AI system has nothing to analyse. If the cameras can’t handle challenging light or if the angles are wrong, it could jump to the wrong conclusions. Compute-intensive technology – Memory, processing power, and power consumption are the biggest challenges within AI, especially for deep learning applications. Today’s systems require vast amounts of space to store data for learning, either in the cloud or on a server with multiple GPUs. Conclusion AI systems have major potential within the field of surveillance, but we are far from having developed human-level intelligence, or ‘true’ AI. It will take some time before we see self-learning surveillance systems that can make accurate assumptions in general scenarios without risking too many false alarms or the violation of people’s integrity. n INTELLIGENTCIO 69
