    Obtaining information is one of the most important requirements for  intelligence works, spy surveillance cameras and listening devices are among the important means for this. One problem of using these means is a mechanism of controlling them to sustain their work efficiently for the perpetuating of achieving the purpose of their installation. In this research, the problem of controlling these devices has been overcome, by designing asystem dependent on the dual tone multi frequency (DTMF) and global system for mobile(GSM) networks. In the proposed work, designing and  implementing a system to remotely and wirelessly control of the movement of spy cameras in all directions as well as the ability to control the on/off listing audio device anytime and anywhere. The proposed mechanism is implementedby dividing the work into nine modes, with each one performing one specificfunction. These work modes are used to control all system activities such as control the horizontal directional motor (HDM) to change the spy camera in different horizontal directions, control the vertical directional motor (VDM) to change the camera in vertical directions and control the working status of the listening device

    In this research, a multi-tasking protection and control device has been designed and implemented has the ability to control and manage automatically the supply of electrical power from various sources to electric appliances connected to the light loading line (3L). At the same time, providing comprehensive protection for the appliances by delaying the supply of power for short period of time during the moment of conversion from one source to other in order to protect it from damage. The mechanism working of the proposed device depends on detecting the problem, diagnosing it and choosing the appropriate solution for it, and then organizing the supply from the appropriate source, and as a result ensure power supply to home appliances
