Smart home refers to a house in which interconnected devices and home appliances are performing certain actions in order to save money, time, and energy. Security and control systems have been among the most popular smart home devices over the last few years. A smart home can integrate the security alarm into a complex system in which other actions are performed, such as blocking exits or providing access to surveillance footage via the Internet. Overall, the smart home security market is forecast to grow to over 30 billion U.S. dollars worldwide by 2023.
Information security refers to the practice of managing access to information. By 2023, the information security technology market is estimated to be worth 151.2 billion U.S. dollars worldwide. Analysts have suggested that security trends are being shaped by new markets, such as big data or the internet of things (IoT). One impact of this has been the shift towards managed security services, resulting in increased revenues of nearly 5 billion U.S. dollars from security appliances at the end of 2019.
Artificial intelligence (AI) technology, hardware or software that can replicate "human" behaviors such as learning and problem solving, is rapidly being implemented around the world. In the AI surveillance space, technologies and solutions involved include smart city or safe city platforms, facial recognition systems, and smart policing. A growing number of countries are deploying these AI surveillance tools to monitor and track citizens, although experts have raised questions as to how lawful some of the methods may be.
