PC-BASED SECURITY

SYSTEM

PROBLEM DEFINITION

The purpose of the project is to come out

with a Reliable Security System. Pictures of thescene under security belt are sent via e-mail tothe user. The PC also initiates a call to the users

phone when there is intrusion. Remote

Controlling the PC is achieved using an

Interactive Voice Response System.

ALGORITHMALGORITHMALGORITHMALGORITHM::::• SERIAL COMM. PORT TO COMMUNICATE WITH MICRO CONTROLLER IS CHOSEN AND PORT SETTINGS ARE SET.

• THE COMM. PORT IS SCANNED FOR INPUT FROM THE MICRO CONTROLLER.

• ONCE THE PROGRAM RECEIVES THE REQUIRED INPUT, THE WEBCAM IS AUTOMATED TO TAKE A PICTURE.

• THE WEB CAM CAN TAKE ‘N’ NUMBER OF PICTURES DEPENDING ON THE REQUIREMENTS.

ALGORITHMALGORITHMALGORITHMALGORITHM::::

• AN ACTIVE-X CONTROL ezVidCap IS USED TO AUTOMATE WEB CAM.

• THE PICTURES TAKEN ARE IN BITMAP FORMAT.

• THE FORMAT OF THE PICTURE IS THEN CONVERTED FROM .bmp TO .JPEG BY COMPRESSION TECHNIQUE (USING Picformat32).

• THE .JPEG PICTURE IS THEN STORED IN THE SYSTEM AND SENT TO USER’S e-MAIL.

• A MISSED CALL OR A SMS MESSAGE IS SENT TO THE USER’S MOBILE / PHONE USING A DIAL-UP MODEM.

• ONCE DIALING A NUMBER IS COMPLETED THE PROGRAM COMMUNICATES WITH THE MICROCONTROLLER

• THE MICROCONTROLLER THEN RESETS ITSELF TO THE INITIAL POSITION AND STARTS TO SCAN FOR INPUT FROM THE IR RECEIVER.
