In this paper, a distributed real time security system for monitoring and remote control on building and protecting it from unauthorized entering is designed and implemented. This system is based on the transfer of signal in real time when there is a breach and image of an unauthorized person to enter the building to the mobile phone of the person who is responsible for the security of the building.
            The real time system consists of three main parts, the first one is the computer with an electronic circuit connected via the serial port. The designed electronic circuit contains the Microcontroller for reading sensors connected to ports of the building (G1, G2, and G3) and processing the signals. Also, there is a monitoring camera to capture an image when registering a case of breach. The program in the computer receives signals from the three ports and uses a fixed real time algorithm for scheduling signals and gives them priorities according to the importance of ports, then sends signals to the second part of the system. The second part of the system consists of a server on the Internet which receives signal and image of the breach, stores it in a database system and then transferring it in real time to the third part. The third part consists of several mobile phones to achieve the principle of distribution for this system, each mobile phone will be responsible for a single port in the building, while there is one mobile phone responsible for all ports which belongs to the person who is responsible for the building security. Each mobile phone contains three programs, the first program would receive a signal of the breach and give the alarm, the second program displays picture, and the third program sends a control signal.

The design and implementation of security, monitoring and controlling system with data communication based on Bluetooth technology is described. The application has been accomplished using wireless Bluetooth USB into the motion detector to demonstrate the establishment of connection and the changing of the motion detector settings. There will be a Graphic User Interface (GUI) implemented on the User Laptop and protocol written to let the user configure the motion detector sensitivity and range also monitoring using wireless surveillance camera.
The study also describes an investigation into implementation potential of remote access methods to laptop using PC Anywhere method. The implementation process consisting of application architecture design, system requirement, software design, hardware design and establish Bluetooth connection is described in detail. Experimental results show that the designed system is more reliable, flexible and easy to use.

The home automation becomes important, because it gives the user the comfort and ease for using the home devices. The implementation and design of wireless home automation control use two methods, WLAN technology and RF remote control handheld to control selective home devices with integral security and protected system. The devices have been distributed in two rooms, each room has own board, these boards are connected to the desktop personal computer (PC) through one serial port RS-232 via microcontroller. The software consists of Assembly Language for programming microcontroller (AT89C51and AT89C2051) and Visual Basic Language that use to communicate between PC and two boards, also it use to design Graphical User Interface (GUI) which involving all devices needed to display in Home PC screen .  The system is low cost and flexible with the increasing variety of devices to be controlled.
