microcontroller 8051 base security alarm using GSM and hidden cameras include keil(c and hex) and Proteus

Design circuit diagram in Proteus as bellow :-

The major building blocks of this gsm based project are:

1> Microcontroller based control system with regulated power supply.
2> GSM Modem or phone.
3> Digital and Analog sensors and controlled devices.

this figure is the circuit diagram of home/office security system. We can see that system has 10 LED's attached to microcontroller(89c51). These LED's can serve 2 jobs.

we can attach any external device with these signals like bulb or camera, or any suitable device using proper optocoupler and relays.

1st  LED is flashing led, which is an indication that the system is running smoothly or not. 2nd LED is for alarm for security problems and remaining8 LED's can be used for controlling cameras in each of the room to take snaps of the person who has un-authorised access to that room.

Thus this is GPS based camera controlled security system for home/offices.
