ABSTRACT
The fear of theft and burglary always annoys many people. When lock and keys become less safe, one can seek the help of electronic security systems.
Such a portable security system is described here.
This electronic setup auto activated whenever the intruder enters to the unauthorized no entry area. 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.
