A facial recognition camera can be seen everywhere, from smartphones to airports, banks, and more. It has taken many years of research and in-depth testing to present this technology as a reliable and trustworthy security source. The backdrop is our face as a means of unlocking everything closest to ours, streamlining transparency and simplicity at once.
However, facial identification systems are not perfect. They require computational technology of external hardware and smart software to accurately identify multiple faces simultaneously. One standout factor amongst all of this is the importance of image quality in making both ends meet.
Why Image Quality Matters?
A facial recognition process can’t take place in dark or poorly lit environments. For a system to identify a person’s face in mere seconds is only possible when the right conditions are met because failing to comply with these factors can lead to reduced accuracy as the algorithm matching rate lowers, sending errors to the system and falsely alerting people leading to security risks and operational efficiencies.
Furthermore, low-quality images pose significant challenges in face recognition systems, particularly when scanning head poses and facial expressions. These two facial attributes are important for reliable recognition, but poor image quality can obscure or misinterpret them, leading to accuracy errors.
Moreover, a blurry image with key landmarks, i.e., eyes, nose, mouth, and jawline, becomes vague and poses a risk when two similar-looking people are trying to log in, making it difficult for AI models to differentiate between slight head tilts or rotations.
Your Facial Recognition Camera Might Be the Weak Link!
A weak camera in a biometric system, especially a facial recognition camera, compromises security and usability in multiple ways depending on the data it has stored. It fails to capture fine facial details, and users may have to scan their faces multiple times.

On the contrary, low-quality cameras fail to capture unique facial traits, making it easier to breach security measures. Even if it captures all the facial data correctly, a low-end camera will perform poorly in bright sunlight or dim lighting, making more errors along the way.
The chances of spoofing and fraud for a high-security building have become largely prevalent. Therefore, it is up to the biometric device to become the first layer of security by including infrared sensors and anti-spoofing technology to detect fake images or 3D custom-made masks.
What to Look for in a Biometric Device’s Camera?
A standard face ID biometric device should offer a best-in-class processor with GPR, LAN support, a top-class algorithm, and at least an RGB + IR camera. Afterwards, extra functionalities and other software add-ons can be introduced to make it better than previous versions or competitors.
Similarly, for a good starting point, you must buy a biometric device with the following features of their camera system:
at least 1080p high resolution
infrared sensors with good low-light performance
a wide dynamic range and fast autofocus
a 3D depth-sensing technology
a high frame rate FPS
Overall, you must ensure to ask the questions or test the system yourself by understanding the advanced exposure algorithms to ensure accuracy across different skin tones. This is important because it has to be tested first to get approval; if the issue is found later, it could hurt the business's brand value.
Additionally, you must prepare for all cases of people from all backgrounds, i.e., all heights, including wheelchair users.
