Patent attributes
An access control system includes an identification unit having an infrared (IR) transmitter that transmits IR radiation, an IR detector that receives the reflected IR radiation from one or more body parts of the user, one or more signal processing components to determine a temperature of the user based on the received reflected IR radiation, and an identification device to receive identification information of the user. The access control system also includes a processor that receives the reading of the user, instructs a door lock controller to unlock a door when the temperature is below the threshold temperature or the temperature is within the temperature range. The processor sends an alert when the temperature is above the threshold temperature or the temperature is outside the temperature range, and sends identification information of the user to one or more network devices.
