Security is one of the most important factors in human life, because with the guarantee of security, people can carry out daily activities easily and without worry about threats to them. Security is very necessary in every place and at all times, both in terms of at home, at work, and in activities or in a state of rest. One place that needs security is a house, where a house is a place to store property, where this threat usually comes from outside like a thief. In this final project I used the PIR Sensor as a motion detector. There are 3 PIR sensors, each of which represents a predetermined angle position, namely the angle 0 °, 90 ° and 180 °. When the sensor detects a movement that produces an Infrared signal, the sensor will send a commands to the servo motor which is connected to the Webcam camera to move automatically following which direction the signal originates and the SMS notification will be sent automatically by SIM800L to the Smartphone User device. When the User receives an SMS notification of the User's movement, User can directly monitor the room by accessing the Webcam camera via Webcam Software that has been installed on the Smartphone.
