The primary objective of the project is designing and implementing a low cost and user friendly home security system which can be remotely controlled from any place by integrating to the existing PSTN telephone line.

Since this is an undergraduate project there are some limitations facing in the process of achieving the objective. As an example there are time schedules and also limitations of available resources. Therefore project scope tends to build a model which simulates controlling few actuators and sensors remotely from any where. With the limited time, actuators like relays and sensors like IR sensors, and a microphone are only controlled by the system.
In general most of the security systems pay their attention for the motion detection using sensors. But as a new area here we mainly concerned controlling actuators like relays, door lock. In addition we are highly concentrated on designing a microcontroller to control those actuators and sensors. Actually that is programming a PIC that could satisfy the overall control of the system model.

If the system use a mobile network instead of PSTN the effectiveness and the applicability is going to be high. But technology of mobile network is a vast area. Technology behind PSTN is simple compared with mobile network. So within our scope communication method based on to PSTN. As a remote control signal system use DTMF signals, because DTMF technology is simple than other technology such as blue tooth, IR, FM etc.
