As we know there are different techniques like keypad input, face recognition, gesture recognition, voice recognition etc. are available for operation of home appliances and door opening and closing in todays world. This paper is basically related with the review of two different techniques of door access i.e., face recognition and voice recognition. First technique is face recognition which is based on mainly three subsystem namely face detection, face recognition and automation door access. While the other technique is based on voice recognition method and door access according to voice input. Process of detecting region of face in an image is a face detection by using a viola jones algorithm and recognition of face with algorithm of principle component analysis. Recognition of face by principle component analysis is referred to as a eigenfaces. If face is recognized either it is known face or unknown. The door will open automatically foe known person with command of microcontroller and alarm will ring for unknown person. On the other hand same concept is used with voice recognition method, voice is recognized if person is known otherwise a unknown person and door will be open for known person.

Viola jones algorithm, Principle component analysis, PIC microcontroller, Arduino, Bluetooth, Voice module, etc.
