3. An Overview of the Multilevel Home Security System (MHSS)

As shown in Figure 1, MHSS comprises of three major components which are the inputs, main control unit and outputs. Each component contains of its sub-components. The input elements are such as thieves’ alarm, presence detecting, and break-in camera that will be triggered if a thief has broken into the covered area. Meanwhile MHSS is divided into three levels where the input elements work simultaneously with the output elements. The inputs elements are formed by the sensor nodes that will react when the system is triggered. Table 1 summarizes the relationship of the inputs and output elements.

The Outcomes of the Triggering from Inputs aare as follows:

Inputs: Laser sensing node
Outputs :Light Bulbs
Explanations:When the circuit is triggered, a signal is sent to the main control unit, and then first set of light bulbs is turned on.
Inputs;Presence detecting
OutputsLight Bulbs
Explanations;When the circuit is triggered, a signal is sent to the main control unit, and then 2nd set of light bulbs is turned on.
Inputs;Break-in node
OutputsWebcam, light bulbs and computer
ExplanationsWhen the circuit is triggered, a signal is sent to the main control unit, and then the 3rd set of light bulbs is turned on. The camera will start capturing images when the third level is violated. The captured images will be delivered to a specified email through the server.
