In this paper, the authors have aimed to improve security systems available in current market. This paper claims to produce a prototype camera and Global System for Mobile communication (GSM) interfacing system for security surveillance. This system uses sensor, namely Passive Infrared Receiver (PIR). The PIR function is to detect changes in temperature of human in infrared radiation. This paper presents a technique for human face recognition based on PCA algorithm (i.e., eigenface method). In this paper, the microcontroller used is PIC 16, where it sends data to the computer to activate the camera when the microcontroller receives signals from PIR. MAX232 is used as an interface circuit connecting the microcontroller to the computer.
