If the detected face does not
resemblance with the owner’s face, the person with detected
face will be concluded as intruder. An improper face detection
(only eyes, which may be interpreted as masked person) also
should be concluded as intruders. A sharp and high frequency
alarm may be generated as the result of this detection in order
to make the neighbour of the house aware of this burglary. This
complete detection method of intruder also includes generation
of a phone call to already registered phone number of the user
who is currently at far away. The complete flow chart of the
work procedure has been shown in Fig. 1.
