The document describes the 'Invisible Eyes' advanced security system, which utilizes a single camera and various components such as microcontrollers and PIR sensors to detect intrusions and alert users via SMS. This system is designed to reduce the complexities of traditional multi-camera setups by recording only upon detecting motion. It emphasizes applications in home, office, and bank security, and addresses both advantages and limitations of the technology.

3. INTRODUCTION
• In this modern era, property crimes are more predominant. This
necessitates our need to develop an advanced security system which
is the INVISIBLE EYES. It is basically a single camera based
security system that can be used to protect valuable kept in a room of
a house or property
• Manager can only view the footage which was alerted on the presence
of intrusion. Once the intruder has been detected this information
about intruder will be directed to the cop through the sms. And the
same time camera can slew around the room and record only when it
is alerted by the presence of any intrusion.

4. METHODOLOGY
This system consists of the following components:
1. Microcontroller
2. Stepper motor
3. PIR Sensors
4. Camera
5. GSM modem
6. Personal computer

5. MICROCONTROLLER
It is a small computer on a single integrated circuit containing a CPU,
memory, Timer and programmable input/output ports
Microcontroller available with different word length such as 8bit, 16bit
and 32 bits microcontroller
Microcontroller can contain a varying number of I/O pins. These pins
can configured to either an input or an output state.

6. STEPPER MOTOR
Stepper motors are digital motors, We
actually
Send Position signals to the Motor to drive
them.
It is of four wire stepper motor.

7. PIR SENSOR
PIR sensor allow us to sense the motion, almost
Always use to detect whether a human has moved
in or out of the sensors range
It is commonly found in appliances and gadgets
Used in homes or business,
Sensitivity Range: up to 20 feet (6 meters)
We, homo sapiens, radiate heat in form of radiation
at wavelength of 10-12 micrometer that can only
detect by the PIR sensor

8. GSM MODEM
It is a special type of modem which accepts
SIM card.
These GSM modem are more frequently used
to provide mobile connectivity.
Many of them can also be used for sending
and receiving SMS.
In this case we are using GSM modem for
sending the message only.

9. WORKING
• Step1: user enters the password, if password entered is correct then the
system starts else he is prompted to re-enter the password.
• Step2: If sensor sense any change or sense any motion, then an intrusion is
detected. Else there is no intrusion.
• Step3: If intrusion is detected, then relay triggered, stepper motor rotates
the camera, it start recording and an e-mail is sent to user

11. ADVANTAGES
• Invisible Eye Security system solves many of the problems
faced by the multiple camera based security system at an
easily affordable cost.
The biggest advantage is that we can avoid having to wade
through hours of footage of empty rooms.
One can also avoid having to install multiple cameras to
cover a single room.

12. DISADVANTAGES
• we have to deactivate the system while your
shop is open
• If the owner is out of network then message
will not be sent.

13. APPLICATIONS
• Use for home security systems.
• Office security system
• Bank security system

14. CONCLUSION
• It is very secure security system as compare to present
security system.
it solves many of the problems faced by the multiple
Camera based security system.
so we can use Invisible eyes instead of present security
system.
