Now a day’s a lot of memory is being wasted using continuous data in the cc cameras, this can be reduced by using motion sensor such that we can record if there is any movement in the concerned area PIR sensors used as motion detectable sensor which are based on heat change from a body .

In our project we us the PIR sensors which triggers the camera to on up to then the camera on standby at the time of triggering the camera we make an sms alert to the concerned user that the recording has been started and then depending up on his reply he can also get the captured motion clip to mobile via mms.

Filter Circuit

•The operation of power supply circuits built using filters, rectifiers, and then

voltage regulators. Starting with an AC voltage, a steady DC voltage is

obtained by rectifying the AC voltage, Then filtering to a DC level, and

finally, regulating to obtain a desired fixed DC voltage.

•The regulation is usually obtained from an IC voltage regulator Unit, which

takes a DC voltage and provides a somewhat lower DC voltage, Which

remains the same even if the input DC voltage varies, or the output Load

connected to the DC voltage change.

In our project we are using the AT89C51

micro-controller. The AT89C51 provides the following

standard features:

• 4K Bytes of In-System Reprogrammable Flash Memory

• 128 x 8-bit Internal RAM

• 32 Programmable I/O Lines

• Two 16-bit Timer/Counters

• Programmable Serial Channel

FEATURES OF MICROCONTROLLER


CONTROLLER CIRCUIT DIAGRAM

PIR SENSORS


• Passive Infrareds sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body.

• The pyroelectric sensor is made of a crystalline material that generates a surface electric charge when exposed to heat in the form of infrared radiation.

• When the amount of radiation striking the crystal changes, the amount of charge also changes and can then be measured with a sensitive FET device built into the sensor.

• This radiation (energy) is invisible to the human eye but can be detected by electronic devices designed for such a purpose

PIR CONFIGURATION


BLOCK PROCESS


• The PIR325 sensor has two sensing elements connected in a voltage bucking configuration.

• This arrangement cancels signals caused by vibration, temperature changes and sunlight.

• A body passing in front of the sensor will activate first one and then the other element whereas other sources will affect both elements simultaneously and be cancelled.

• The radiation source must pass across the sensor in a horizontal direction when sensor pins 1 and 2 are on a horizontal plane so that the elements are sequentially exposed to the IR source.

GSM MODEM


• A GSM modem is a wireless modem that works with a GSM wireless network.

• A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.

• A GSM modem can be an external device. Typically, an external GSM modem is connected to a computer through a serial cable or a USB cable.

• Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate.

AT COMMANDS


• Computers use AT commands to control modems. Both GSM modems and dial-up modems support a common set of standard AT commands.

• GSM modems support an extended set of AT commands.

OPERATIONS


• Reading, writing and deleting SMS messages.

• Sending SMS messages.

• Monitoring the signal strength.

• Monitoring the charging status and charge level of the battery.

• Reading, writing and searching phone book entries.

•Serial data communication uses two methods, asynchronous and synchronous.

•The synchronous method transfers a block of data (characters) at a time while the asynchronous transfers a single byte at a time.

•It is possible to write software to use either of these methods, but the programs can be tedious and long.

•For this reason, there are special IC chips made by many manufacturers for serial data communications.

•These chips are commonly referred to as UART (Universal Asynchronous Receiver-Transmitter) and USART (Universal Synchronous-Asynchronous Receiver-Transmitter). The 8051 chip has a built-in UART.

SERIAL COMMUNICATION


• The MAX232 from Maxim was the first IC which in one package contains the necessary drivers and receivers to adapt the RS-232 signal voltage levels to TTL logic.

• It became popular, because it just needs one voltage (+5V or +3.3V) and generates the necessary RS-232 voltage levels.

DVR

Name: Digital Video Recorder

Description : DVR uses a Hard Disk Recorder (HDR) to digitally record the data that are been captured DVRs record in real-time, which allows you to pause or rewind at any point in the program

Working : The cam triggers with a switch and starts recording .It stores the data in its memory . And USB port which is in built helps to connect to PC to view the captured data.


RELAYS

Description : An electromechanical or solid-state device operated by variations in the input which, in turn, operate or control other devices connected to the output.


Name: Relays Circuit

Working : We can think of a relay as an electromagnetic switch. Apply a voltage to the coil and a magnetic field is generated. This magnetic field sucks the contacts of the relay in, causing them to make a connection. These contacts can be considered to be a switch. They allow current to flow between 2 points thereby closing the circuit



FINAL RESULTS

•Hence by using M-QUBE surveillance system we can overcome the draw backs of old surveillance systems. And we are minimizing wastage of time and memory and man power which is a great advantage to us.


CONCLUSION

• It can be concluded that with the use of excellent architecture of microcontroller of chips, any complex electronic systems can be developed based on flexible software with minimum hardware components.

• Developing any application systems using microcontroller, its assembly language is very easy to its versatile nature.

•The present project can be modified to control any other device using Micro controller based applications with little modifications in the circuit and the program this project can be extended to some other important applications such as video call based surveillance system etc...


FUTURE SCOPE

• In future this M-QUBE SURVIELLANCE SYSTEM Project can be extended to implement using video calling via 3G technology

•The user can directly view the concerned area in his mobile without any delay by live streaming.

•This reduces the human interference requirement and also increases reliability on the security systems.

• Along with the reduction of the power consumption, memory usage and time required to view all the data recorded in the security cameras is also reduced.
