StoneLock® Pro is a sophisticated biometric facial recognition access control device that provides instant, reliable confirmation of identity without storing sensitive personally identifiable information (PII). Once a face is detected, the StoneLock device uses near infrared wavelengths to scan over 2000 points in less than a second and confirms or denies a match within its database. StoneLock technology is proven to distinguish between identical twins and multiple expressions on an individual user’s face. All of this happens independent of ambient light and without the use of photos, ensuring the correct person is gaining access even in total darkness.
