This paper presents an approach to the detection of objects in a fixed frame. In this approach, an acoustic sensor is used for detecting any change in the surrounding of a fixed frame, i.e. detecting the entry of a foreign object. If it so happens, then the sensor sends a signal to the system which is processed. If the sampling result crosses the fixed threshold then the camera is switched on. It clicks a snapshot and then again is switched off. With this snapshot, we operate frame difference against an initially stored snapshot of the fixed frame. Based on the difference, we determine the nature and type of the foreign object.
