3. INTRODUCTION
Surveillance system are inevitable
which uses more than one
cameras today.
Here we introduces a new system
for surveillance that has only PIR
sensor, MCU and a smartphone .
8. PIR SENSORS
• PIR sensors works on pyroelectricity principle.
• PIR sensors consists of a pyroelectric element.
• The PIR sensor detects the infrared radiation emitted
or reflected from an object.
10. PIR SENSORS
• PIR sensors can be operates on two voltage
levels(3.3v and 5v)
• The PIR sensor can detect motions up to 7m
vicinity but its direction probability is high
within 4m.
12. SENSOR INPUT LOCKING
SYSTEM
• Continuous stream of high and low signal is send to
MCU when there is motion or not from PIR output.
• To get an exact time slot of the motion a simple input
locking mechanism is implemented using a lock
variable.
13. SENSOR INPUT LOCKING
SYSTEM
• Output state of the sensor changes from LOW
to HIGH then the lock variable is made TRUE
else it is FALSE.
14. CLOUD STORAGE
Cloud storage is a model of data storage where the
digital data is stored in logical pools and the physical
environment is typically owned and managed by a
hosting company.
16. ADVANTAGES
• Smartphone is used as the eye of the system.
• Reduces lot of energy.
• Whole design is compact and easily
mountable.
• Cloud storage solves the storage issues.
18. CONCLUSION
• A new method for intelligent surveillance utilizing the
capabilities of a smartphone along with PIR sensor.
• The energy usage is reduced by activating the
camera only when the movement is detected by PIR
sensor.
• As a future work, the efficiency of our design can be
further improved by adding more sensors to it.
