Authentication inside.

Intel RealSense ID F455 What's inside

An SOC for data processing on device, with dual cameras for authentication, IR illuminators to allow indoor and outdoor operation, the Secure Element to protect your privacy and a specialized neural network to adapt over time.

Small and mighty.


Facial authentication module F450 is smaller than a credit card


Facial authentication peripheral F455 smaller than a credit card

Smaller than a credit card, but powerful enough to authenticate reliably in less than a second.

Secure entry everywhere you need it.

In industries like Finance, Healthcare, and Smart Access Control you need technology you can trust. Intel RealSense ID delivers scalable facial authentication for edge, local host or cloud solutions.

Facial authentication code samples

Code Samples

Check out how easy it is to get started with Intel RealSense ID.

// Create face authenticator instance and connect to the device on COM9    
RealSenseID::FaceAuthenticator auth {&sig_clbk};
auto connect_status = authenticator.Connect({RealSenseID::SerialType::USB, "COM9"});
// RealSenseID::SerialType::UART can be used in case UART I/F is required
// Enroll a user
const char* user_id = "John";
my_enroll_clbk enroll_clbk;
auto enroll_status = authenticator.Enroll(enroll_clbk, user_id);    

// Authenticate a user
my_auth_clbk auth_clbk;
auto auth_status = authenticator.Authenticate(auth_clbk);    
// Remove the user from device
bool success = authenticator.RemoveUser(user_id);

// Disconnect from the device

Authentication can be 1:1 or 1:N.

No. Intel RealSense ID is a complete solution that includes hardware and software. There are two form factors – Intel RealSense ID F450 Module and Intel RealSense ID F455 Peripheral.

Yes. Intel RealSense ID supports medical face masks.

Yes. The authentication algorithm is designed to adapt to changes within reason.

Intel RealSense ID is mainly designed for Facial Authentication. Facial Authentication use cases that need multiple devices are typically positioned side-by-side or in parallel. These configurations are unlikely to have IR noise interference. Further, the short period of IR burst is unlikely to cause interference.

Intel RealSense ID is a peripheral device that can connect to any host that supports IFTTT via the published interfaces like USB 2.0. Please see technical specification for more information.

There is no limitation on the number of faces up to 10,000. For usage models beyond 10,000, please contact us.

Intel RealSense SDK 2.0 is meant to used with Intel RealSense depth and tracking cameras. Intel RealSense ID SDK is only used by the Intel RealSense ID F455 peripheral and F450 module.

Yes. Intel RealSense ID solutions are designed for continuous usage without performance issues.

Yes. Intel RealSense ID is a self-contained solution that includes the necessary hardware and software. The solution is purpose built for facial authentication and is designed for stand-alone (edge) or connected configurations.

No. Intel RealSense ID is not designed for authenticating animals.

Yes. Intel RealSense ID supports up to 5 people in the Field of View.

The solution does not store or need any user pictures. It is designed to use facial templates which are encrypted before being stored. Depending on the configuration, this can be stored locally or externally.


Currently, the solution is designed for authentication and not explicitly designed for tailgate detection.

Please see the datasheet for more information.
