This project is developed for the users to have security through Laser. Usually if someone tries to enter inside the bank, the security unit produces siren. But this project is specially designed to make a call to the owner and intimates the administrator that there is something strange.

The main part of the Unit is Microcontroller and Laser Transmitter and Receiver and Telephone. In normal operation, the laser light is blocked by the cash box and therefore no laser light falls on the laser receiver.

If some one tries to take the cash box, the laser rays immediately falls on the receiver and the sensor senses and sends signal to the Microcontroller unit. The micro controller immediately handles the phone operation completely.

It first handles the hook button and then flash key simultaneously for some time and then starts dialing to the particular numbers already set.

If the owner and other numbers set are busy, again and again it tries to the particular numbers. When they attend the phone, the Unit tells the message through the Microphone. Thus the owner has to come and handle the situation.

This project is very useful in Bank, Houses, Industries, Institutions, Shops etc where hitech security is needed
