Abstract :
At this time technology and information have developed rapidly and rapidly. Various
new technologies began to emerge one of which is technology in the field of security
systems. Starting from private offices to national scale institutions need a security
system to ensure the goods and documents inside are not taken or stolen. One of the
devices used in security systems is CCTV (close circuit television) technology. The
purpose of using CCTV is to provide a sense of security to its users, but only to the
extent of monitoring. However, with the development of security technology there are
several security systems that can already secure themselves automatically. One of them
is a webcam security system based on face detector. Face detector allows the webcam
to detect the face of a user or employee in an institution by storing people's face data in
front of the camera, the stored image will later be used again to find the face of the
person in the picture. using the Logitech C270 HD Webcam camera, utilizing the
MG995 servo motor controlled by Arduino Uno R3, which moves up, down and rotates
180?. Using the Microsoft Visual Studio C ++ programming language and assisted with
libraries from OpenCV or Intel's open source computer vision library, to detect the
user's face. The detected results were successfully entered. The accuracy of distance
testing is 60% and for face position accuracy testing is 60%. The accuracy rate of
testing the light conditions from 20 times the test is 70%. The coordinate test failed, the coordinates read only 0.0, which caused the motor to die and the camera could not
follow the face.
