Title: Infrared biometrics information collection device and door locks having the same

Description:
FIELD 
     The present disclosure generally relates to user authentication, and more particularly to infrared biometrics information collection devices, and door locks having the infrared biometrics information collection devices. 
     BACKGROUND 
     Infrared biometrics information collection devices can be used for user authentication with high accuracy, and this technology has been widely used in many security areas except residential or office entry doors. Conventional infrared biometrics information collection devices are mostly used in-door such that the infrared biometrics information collection devices are not interfered with broad light spectrum, and the infrared biometrics information collection devices are operated in suitable room temperature instead of extremely high or low temperature. The application of this technology to the residential or office entry doors presents us a challenge that the infrared biometrics information collection devices must be used out-door, and must be able to overcome the light interference and extreme temperature. 
     Therefore, heretofore unaddressed needs still exist in the art to address the aforementioned deficiencies and inadequacies.
