This paper highlights the drawbacks of the current security systems for museums and banks. Accordingly, it introduces a design of an efficient and simple security system. The system is based on the fact that any human being radiates an infrared radiation. The proposed security system consists of antenna working at IR frequency band, Programmable System on Chip (PSoC), and a Silicon Controlled Rectifier (SCR). The output of the SCR will activate a load which could be a buzzer or Light Emitting Diode (LED) to give either a sound or a light alarm, respectively. If any human being approached valuable protected item, the antenna collects the infrared radiation and gives an analogue output equivalent to this radiation. The paper describes the design and implementation of the proximity alarm system. The system is tested and found working successfully. Advantages of the proposed security system are: immediate response, no apparent components, no interference with daily business, and possibility of automatic or all-the-time activation.
