The evolution of facial recognition technology?

Over the years, facial recognition technology has grown in sophistication, accuracy, and reach, largely due to developments in related fields such as artificial intelligence (AI), machine learning, and IoT.

Facial recognition technology started out using simple 2D image comparisons. Early systems would compare faces captured on a camera to a library if 2D images. They would generally use techniques such as Eigenfaces, which involves identifying critical facial features, such as the distance between your eyes or the shape of your nose. However, these systems had limitations, particularly with lighting, angles, or changes in facial expressions.

As technology evolved facial recognition began to move away from 2D image comparisons in favour of more sophisticated 3D modelling. 3D facial recognition software and technology uses depth sensors to capture more detailed information about the shape of your face, improving recognition accuracy. 3D modelling greatly enhances the system’s ability to deal with changes in lighting or the angle at which the face is viewed, making it much more reliable than the legacy 2D technology.

One significant advancement of 3D facial recognition was the advent of facial landmarks or nodal points. Current facial recognition technology typically examines around 80 nodal points on a human face. These include the length and width of the nose, cheekbone shape, and the distance between the eyes. By comparing these nodal points, the system can accurately analyse and identify faces.

With improvements in computational power and AI algorithms, facial recognition systems have become capable of real-time verification. This means they can identify and verify individuals as they appear in live video feeds rather than relying on still image comparisons. This is particularly useful in surveillance and security situations, where the rapid identification of individuals is crucial.

The Internet of Things (IoT) has further propelled the growth and reach of facial recognition systems. IoT technology has made it possible to connect facial recognition systems to a network of devices, allowing them to be deployed on a larger scale and in a broader range of environments.

With IoT, facial recognition can now be integrated into everyday objects and systems, such as smartphones, doorbells, and security systems. It can be used in various environments, from high-security facilities to retail stores, hospitals, and even entire cities. The IoT has opened up endless possibilities for facial recognition technology, truly transforming how we live and work.

How IoT empowers facial recognition

IoT empowered facial recognition technology has opened new frontiers in various industries, from security to retail, healthcare, and more. IoT connectivity is improving the scalability and real-time capabilities of facial recognition systems, thereby enhancing their effectiveness significantly.

Enhanced connectivity

IoT technology connects devices via the internet, allowing them to send and receive data. When applied to facial recognition, cameras equipped with this technology can be strategically placed in various locations and connected to a central network.

For instance, cameras might be installed at the entrances, exits, and other strategic points throughout a facility in a security setup. The data captured by these cameras is then transmitted to a central system, allowing for real-time analysis and response.

In some instances, these systems may need to be deployed in remote locations where network stability may be poor. In these instances, a multi-network roaming solution may be deployed to maximise coverage and reduce the risk of down-time.


IoT also brings scalability to facial recognition systems. Traditionally, the deployment of these systems might have been limited by the need for direct, physical connectivity to a central system. However, with IoT, facial recognition devices can easily be added to an existing network, allowing systems to be scaled up or down according to an organisation’s needs.

Real-time capabilities

One of the most significant benefits of IoT-enabled facial recognition is the capacity for real-time operation. Connected facial recognition devices have the capability to continuously stream data to a central system, where it is processed in-real-time.

In a security context, this enables faces to be identified during a live video feed and a compared to a database of known individuals. If there is a match, the system will instantly alert you to their presence, allowing you to take necessary action. In a retail setting, real-time facial recognition could help you identify VIP customers when they enter your store, allowing your staff to provide a more personalised service.

IoT empowers facial recognition algorithms and systems to operate more effectively and efficiently, providing real-time responses and the ability to operate on a larger scale. It is a clear illustration of how combining different technological innovations can result in a whole that is much greater than the sum of its parts.

Applications of IoT-empowered facial recognition

Security & surveillance

IoT-enabled facial recognition systems are used in security and surveillance to identify unauthorised individuals and prevent access to restricted areas. These systems are used to alert security personnel when they detect a face that isn’t recognised or is flagged in their database, enhancing security measures.

Smart homes & smart buildings

IoT-empowered facial recognition also shapes how we interact with our homes and workplaces. Some smart homes use this technology to offer personalised experiences based on the identified resident. It can also be used for access control in office buildings, replacing traditional key cards and fobs.


When it comes to IoT in retail, facial recognition can be used to identify frequent customers and provide personalised shopping experiences. It can also help to flag known shoplifters using physical security systems, helping to prevent theft.


In the hospitality industry, IoT-empowered facial recognition can be used to enhance customer service by identifying VIP guests as soon as they enter the premises. Hotels can use this technology to provide more personalised services to their guests, thus improving their overall experience.


Facial recognition systems can be used alongside IoT in education to improve on-site security, monitor attendance, and even personalise teaching methods. For example, China are trialling facial recognition cameras in classrooms to monitor students’ engagement and alert teachers when a pupil seems distracted or disengaged.

Banking & finance

When it comes to IoT in banking, facial recognition can be used for identity verification, enhancing security and reducing fraud. For example, ATMs equipped with facial recognition technology can ensure that only authorised users can withdraw money.
