The objective of this research is to build a low cost smart camera base for tracking users for uses in live recording or online teaching. The camera base can be able to detect the position of a user or instructor who is teaching in front of the class using three motion sensors (PIR) that are installed 5 centimeters apart horizontally. It can create 5 sensing zones which are far left, left, middle, right and far right zones. When the smart camera base can specify the position of the user, it will rotate the camera to the position where the user is. The best detecting distance is at three meters away and it has an angle of rotation  from the center. In addition, the smart camera base can be controlled wirelessly so that the camera is pointing in a predetermined direction, such as a projector screen. From the test results, the smart camera base has no more than 9.33 percent () error.
