Laser Security System

The laser based security system is designed to provide maximum security to a given restricted area where the presence of any person is not desired. If someone tries to pass over the boundary line defined by laser lights, an alarm will be triggered and a sms to the authorized person will be sent. Proper messages will also be displayed on the LCD.

The Principles of Laser Security Systems

There are three essential components to a laser security system: a laser, a detector and sensing electronics. The laser is a concentrated light source that puts out a straight line “pencil beam” of light of a single color. The detector is sensitive to light and puts out a voltage when the laser light hits it. The detector is connected to the sensing electronics. When the laser beam is interrupted and can’t reach the detector, its voltage output changes, and the electronics sense the change and put out a warning signal.

LASER System

The word LASER stands for Light Amplification by Stimulated Emission of Radiation. These are available in different types like semiconductor, infrared, GaAs laser diode.

Laser technology products will calculate distance by measuring the time of flight of very short pulses of infrared light. It is different from the traditional surveying instrument method of measuring phase shifts by comparing the incoming wavelength with the phase of the outgoing light pulse.

The Warning Signal

Laser security systems are available in many configurations, with many levels of sophistication. There are do-it-yourself kits that will buzz or ring when the beam is interrupted. The electronics can also trigger the exterior lights of the house to flash, helping police locate the house where the alarm has been triggered.

Advantages of a Laser Security System

These are easy to install and work at both within as well as outside houses. In indoor systems can utilize the normal power outlets and jacks making them inconspicuous. At outside these can be easily be hidden behind the bushes or plants without causing any damage. They Consume less power when compared to the laser system as the whole, which is expensive.
