Infrared Face Unlock: Do Not Infer It from a Night-Vision Camera

A phone with an infrared or night-vision camera should not automatically be described as having infrared face unlock. The camera's imaging role and the device's authentication implementation are separate capabilities.

Ask what authenticates the user

Request the exact face-unlock implementation, supported enrollment process and available authentication functions. Ask the software provider which authentication strength the intended app requires.

• Confirm that the supplied variant actually supports the requested unlock method.
• Check enrollment, normal unlock and the documented fallback credential.
• Verify whether the production app accepts that authenticator.
• Retain the device and software version with any approved security evaluation.

Use Android's distinction

Android's biometric overview distinguishes biometric strength classes and explains that integration depends on security properties, not merely whether the modality is face or fingerprint. A camera label does not assign a strength class.

A current camera example

The R4-T listing specifies a 20MP night-vision camera and a separate front camera. Those facts do not establish infrared face authentication or a tested anti-spoofing result. This guide provides no security certification or biometric trial; confirm the exact implementation before using it to satisfy an access requirement.
