It auto activate the landline number and redial the last dialed number from the conventional telephone. All we need is to do minor changes to activate this telephone as it works as to become auto dialer circuit.
Thus whenever the intruder enters to the area, it activates the sensor circuit of either sound activation or infrared light beam obstruction circuit, the redial circuit become active and give a ring tone to the receiving end. It may be a mobile phone or any landline phone or even police control room.
I hereby declare that this submission is own work and that, to the best of my knowledge and belief, it contains no material previously published or written by another person nor material which to a substantial extend has been accepted for the award of the award of any other degree or diploma of the university or other institute of the higher leaning except where due acknowledgement has been made in the text.
