Project Summary

Security is a most important factor today. Technology develops day by day in the world. The crime gang also improves their technology to perform their operation. So technology of security should be modern with time to protect the crime works. We decide to make a security project as our project. In this project we have used laser light to cover a large area The idea of LASER (Light amplification by stimulated emission of radiation) based security system with LDR (Light dependent resistor) in which an alarm was sounded when an intruder as detected. LASER is high directional and travels a very long range without losing sufficient power. LASER light even goes through long distance without scattering effect. It’s also visible only at the source and incident point; otherwise invisible. In dark, a LDR can have a very high resistance (several mega ohms (M?)), while in the light; it can have a low resistance in the order of ohms. This property of LDR helps to sense LASER. These properties help us to build up a modern security system, which may name as laser security. When any person or object crossover the laser line the security alarm will ringing and also the focus light will on to focus the entrance of unauthorized person. The project is about security system for the organization, companies, institutes, banks, schools, and restricted areas as well where we can install and make our places very safe from any attacks or robbery. In a high-secured place where nobody is allowed to enter, this is easy to install and work at both within as well as outside houses. As we know that today we are facing the security issues, in this way we guard our location for this purpose and still we could not feel safe for our concern. Therefore, it’s earlier to be secure for high demand we need to work on these issues. Our project is about to safe and secure our alliance.

We have seen these projects like detection based alarming, passing through alarm by cutting the laser. And the alarm signals the security monitoring company and local law enforcement. The basic alarm unit will also sound a loud alarm. Both analysis and experiment indicate that rather stringent requirements must be met in order to obtain efficient optical heterodyne detec-tion. At some wavelengths it may provide the only means of  ring the siren which alert the system to take action immediately. As we have seen laser security system has not implemented frequently. It is manually switch dependent sensors and a basic alarm unit. Laser security system a person moves in front of the sensor, that person triggers the system's alarm by cutting the laser.

Project Objectives

• To survey the existing methods related to laser security systems.
• To use a single or two laser sources along with mirrors to increase the coverage of area.
• To evaluate multiple positions for increase the pattern complexity of laser sources for enhanced security.
• To integrate the laser sources with any physiological trait authentication system such as keypad, biometric or facial recognition system..
• To perform the cost analysis for existing systems and the proposed one.

Project Implementation Method

Laser based security is based on the interruption of Laser beam. The laser pointer is used as the source of light beam. If somebody tries to break the laser path, then an alarm will be generated in a few seconds. Normally laser door alarm circuit will have two sections. First, one, laser transmitter is a laser pointer readily available. This is powered with 3-volt DC supply and fixed on one side of the door frame. The receiver will have a Phototransistor at the front end. It is manually switch dependent sensors and a basic alarm unit. Laser security  system a person moves in front of the sensor, that person triggers the system’s alarm by cutting the laser. And the alarm signals the security monitoring company and local law enforcement.

Benefits of the Project

Technology develops day by day in the world. The crime gang also improves their technology to perform their operation. So technology of security should be modern with time to protect the crime works. We can make a security boundary of single laser light by using mirror at every corner for reflection. Siren is a device that produces loud noise. Sirens can be seen in emergency vehicles such as police cars, ambulances and fire engines. Generally, sirens are used as indication or warning. There are different circuits to produce different sirens. Here in this project a screaming siren lights circuit is presented. Screaming siren lights are those which produces siren depending on the light intensity falling on the circuit. We can also call it as Laser Based Security alarm as it is a Light Activated Alarm circuit LDR is place at that when the thief enters our house then a connection of beam of light and LDR is disrupted by the intruder and the buzzer goes off. When a ray of light is interrupted by anything, the LDR used in the circuit changes its resistance and causes the buzzer to go off, producing a large siren, scaring the intruders away. Circuit can be easily modified to make the police siren a simple alarming sound. If once the alarm circuit is on it will still ringing until push the reset button. There is two option of ringing. One is the duration of ringing depends on preset timer and another reset manually. If anybody wants to bind a sensitive area with the single ray he has to use mirror at every corner to reflect it. The system has built with low cost and high performance. The power consumption of the system is very low. These laser systems can be installed in homes either by self or by hiring a technical person. By technological innovations, cost of the security systems has been cut largely. Therefore, making laser systems one among affordable security system options can be very safe. It has ability to work continuously; it is not only human but also a small animal or any other movable objects. Its alarming Sound does not stop until anybody stops it after checking. Now we can use this system in a wide range of area.

Technical Details of Final Deliverable

We made the laser security in low budget. It had been protect in full security. Laser security systems are a high technology that used to be a part of home security only available to the wealthy. It is manually switch dependent sensors and a basic alarm unit. Laser security system a person moves in front of the sensor, that person triggers the system’s alarm by cutting the laser. And the alarm signals the security monitoring company and local law enforcement. The basic alarm unit will also sound a loud alarm. Both analysis and experiment indicate that rather stringent requirements must be met in order to obtain efficient optical heterodyne detection. At some wave lengths it may provide the only means of overcoming noise and detect noise problems. The operation of LDR depends upon the photo conductivity process. Nowadays, in our daily life, the home-security system was popularly adopted, but in most occasions the security system was usual-ly occupied or organized by big insurance companies or spe-cific security companies. That means users need to pay higher money for management fee to protect the safety of their own houses. In this paper we develop another home-security sys-tem combining with some brand-new technologies such as wireless sensor network .This security system has been tested under many conditions and has given a satisfactory result and has proved to be very efficient. Some improvements in its technical and aesthetic design can be expected in the future.
