The development of the Artificial Intelligence of Things (AIoT) is powering the intelligentization of digital buildings. Card access systems are a mainstream and traditional way of building access. However, as cards can be easily forged, lost or "borrowed" to people without identity verification, so new smart solutions are increasingly demanded. As a result, human face, one of the most secure and intuitive biometric IDs, has been gradually accepted to replace the traditional card access system in smart buildings for a secure and efficient whole-building access experience for users.

Since the global outbreak of the COVID-19 pandemic in 2020, people around the world have become much more aware of public health and disease prevention and pandemic control is now becoming a normal part of the daily life. Accurately and efficiently testing people's temperature is regarded an effective measure to monitor potential cases and becomes a top priority for smart buildings and campus as they strive to secure public health while minimizing disruptions to maintain smooth visitor experience. Therefore, the solution combining face recognition and contactless temperature measurement is increasing adopted in smart buildings, which can detect forehead temperature and accurately match data to individuals identified through face recognition technology.

Industrial campus, as the intermediate interfaces between buildings and cities, are crucial to the holistic development of urban spaces. They are sites of work and leisure, reflecting the transformation and application of technological innovation and the integrated development of economy.
