Abstract

INVISIBLE EYE - AN ADVANCED SECURITY SYSTEM

Description:In this modern era, property crimes are more predominant. This

necessitates our need to develop an advanced security system which is the

INVISIBLE EYE. It is asically a sin!le camera ased security system that

can e used to protect valuales "ept in a room o# a house or property.

$ost e%istin! camera ased security systems involve the use o#

multiple cameras placed around the room to e monitored. These cameras

continuously record video #oota!e o# the room and save it on a central

monitorin! station.

Instead o# this, we may use a di##erent system in which a sin!le camera

is used, that can slew around the room and record only when it is alerted y

the presence o# any intrusion. Such a system would consist o# three

components - sensors that detect intrusion& the camera that slews to the point

o# intrusion and ta"es pictures& and the "eypad that is used to inter#ace with

the system which allows any person to disale the system y enterin! the

ri!ht password.

Objective:To desi!n advanced security with an a##ordale and less comple%

system re#erred as 'Invisile Eye(

In the security system the microcontroller is pro!rammed in such a way

that i# someody had entered in home with out permission the sensors will

detect and !ives an interrupt to the microcontroller, i# the controller is

interrupted it will !ive commands and user numer to the modem to sent the

alert S$S to the owner moile.

L@ is connected to microcontroller as 8 it data mode, e#ore

displayin! anythin! in L@ InitialiCation have to do ,so microcontroller will

control the L@ initialiCation and select the data re!ister and command

re!ister accordin! to the purpose.

$emory is connected to microcontroller usin! two pins, it is

communicatin! with the microcontroller throu!h I2 communication.

=elay and uCCer is controlled y the microcontroller usin! sin!le pins,

Ie !ivin! hi!h means device will switch on and vice versa. Sometimes it

may e interchan!e accordin! to the transistor used to drive the device.

hi!h. It must e connected to a transistor, @arlin!ton or transducer driver

susystem.

The uCCer is connected etween the supply rail FH VG and the input

si!nal. This acts as load on the driver. ;hen the input si!nal comin! into the

uCCer susystem is low, a potential di##erence across the uCCer causes

current to #low. It is this #low o# current that causes the uCCer to sound.
