WIRELESS BASED BANK SECURITY SYSTEM USING SENSORS.
ABSTRACT
Pyroelectric sensors are low-cost, low-power small components commonly used to trigger alarm in the presence of humans or moving objects by means of black body radiation, the use of an array of pyroelectric sensors can lead to extraction of more features such as direction of movements, speed, number of people and other characteristics. In this work a low-cost pyroelectric infrared sensor based wireless network is set up to be used for tracking people motion. A novel technique is proposed to distinguish the direction of movement and the number of people passing. The approach has low computational requirements, therefore it is well-suited to limited-resources devices such as wireless nodes.
PRESENTLY AVAILABLE SOLUTIONS
Auto dialer system.
Remotely operated system using land lines.
DISADVANTAGES:
Depends fully on cable connecytivity.
Only one way communication.
Unable to take any local and immediate action.
Proposed system
In this security system we are sensing the human movements by means of PIR sensors and alerting the security and the police simultaneously using zigbee and gsm wireless networks.This system automatically gets turned on when the bank gets closed this is mainly done by means of IR sensors.
Advantages
Two way communication can send and receive messages.
Land line disturbances not involved.
No maintenance required.
Operates on any gsm network SIM card.
User friendly start up.
APPLICATIONS
Protection of premises
Remote operation & control
Data transfer
Control room solutions
Manual control
Process control
Real estate surveillance
Alarms and controls,
Car alarm
House alarm
Boat alarm
Gsm module
A GSM modem is a wireless modem that works with GSM networks. A wireless modem behaves like a Hayes compatible dial-up modem. GSM modem sends and receives data through radio waves. A GSM modem can be an external unit or a PCMCIA card (also called PC Card). An external GSM modem is connected to a PC through a serial cable, a USB cable, Bluetooth or Infrared. Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate.PC's use AT commands to control a modem.GSM modems support an extended set of AT commands. These extended AT commands are defined in the GSM standards.
With the extended AT commands, you can do things like:
Read, write and delete SMS messages.
Send SMS messages.
Monitor the signal strength.
Monitor the charging status and charge level of the battery.
CONCLUSION
We proposed a novel configuration for the sensors and a set of features that can be easily calculated by typical wireless sensor nodes based on low power microcontrollers (e.g. 8 bit ones).As it is a wireless based technique without the knowledge of the thief we can alert the security and the police station with the alert signal and the LCD display, also their exists a credit of switching on the system automatically.
The future advancement that can be done in this project is that we can transfer a live video of about what is prevailing there using 3G technology.
