| Abstract | ||
| The work presented in this paper intended to design and implement a new security system which can be used to protect important places by calling the place owner through a mobile phone to indicate him that the protected place is impenetrate. The system consists of five hardware parts: sensing system (laser circuit and control circuit), Digital Video Recorder (DVR) system, calling circuit, delay and ignition circuit and reset circuit. The Laser circuit of the sensing system connected with the control circuit to detect unauthorized intruder and motivating control circuit. The control circuit which used PIC 18F452 as a major part in its operation is response for controlling and activation the calling circuit and DVR. Where, DVR is used for monitoring protected places and recording the important events. While the calling circuit is used to establish calling with the remote mobile. Ignition circuit is employed to make delay and renew the ignition signal to continue activation the calling process. When need to reset the system, reset circuit utilizes for stopping the calling and reset the microcontroller to complete the function of security system. The mechanism of calling circuit depends on the speed dialing technique in mobile phone by saving the number of the owner in the key no. 2 of the mobile phone device. The novel work was implemented to make it more reliable system than other security system by its possibility for warning the owner in far-away places and recording the events. Keywords: security, laser system, PIC microcontroller, camera system and mobile phone. | ||
