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.

An apparatus and method for validating a leak survey result obtained from an Optical Gas Imaging (OGI) device is proposed. The validation system is coupled to a gas detection infrared thermography camera that captures the infrared image of a scene which may or may not include a gas plume. The validation system performs operations to validate the leak survey result, which includes acquiring a background temperature of each pixel of the infrared image of the scene, acquiring a temperature of the gas plume or ambient air from a temperature sensor that is coupled to the validation system, calculating a temperature difference of said each pixel between the background temperature of said each pixel and the temperature of the gas plume or ambient air, comparing the temperature difference of said each pixel to a predetermined threshold value, and determining whether the leak survey result of the infrared thermography camera is valid based on the temperature difference of said each pixel.
