What is laser security alarm system?

What is laser security alarm system?

Laser based Security System is a type of security and alarm system that uses laser light and a light sensor. A security system protects our homes, offices, banks, lockers etc. from intrusion and unauthorised access. Even though it is a low power laser, avoid direct eye exposure of laser.

How do you make a laser light alarm?

As soon as you connect the battery the L.E.D and buzzer will come “ON” (if you’re in a dark room). Focus the Laser diode/light on the LDR and you will see the L.E.D and Buzzer going “OFF” If you interrupt the laser light focusing on the LDR the circuit will trigger and the alarm will ring!

Are laser beam alarms real?

If you’ve ever seen Get Smart, Ocean’s 12, or any other spy or heist movie, you are probably familiar with the trope of a security system that utilizes laser beams. In real life, laser beams are not fully visible red lines, and many are actually invisible. In security alarm systems, lasers serve the purpose of stealth.

What do you know about laser?

Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. Laser is an acronym for “light amplification by the stimulated emission of radiation.”

Is infrared a laser?

An infrared laser is a low cost, high power laser with many capabilities. These lasers are small and light, allowing for operation without a high input power requirement. Infrared light is radiation in the non-visible spectrum, which extends from 1300 to 1700 nm.

Do burglars cut power?

How burglars disable alarms. A burglar can cut your power source or phone line to disable your wired alarm. And as cellular systems become more popular, thieves are finding ways to bypass those too.

What are the 3 main parts of an alarm system?

The main components of a alarm system would be a sensor, a camera, a motion detector, a buzzer a flash light and batteries. It is a component that is usually used to detect noise or a movement. Sensors are usually connected to the circuit.

How does a laser security alarm circuit work?

Laser security alarm circuit produce highly audible buzzer beep sound when the laser light blocked. Here LDR placed to sense the laser light from the laser diode. Two NPN (BC548) transistors implemented in this security alarm circuit as a switching device.

When does a laser alarm make a sound?

This Circuit produce alarm sound when the laser light continuously blocked. LASER lights are dangerous to the bare eyes, handle with proper protection and care. This circuit requires proper positioning of LASER light and LDR.

How much power does a laser alarm need?

The laser alarm system is an economical option when it comes to consumption of power, as the receiver needs power supply less than 10 mA on average. Setting up a laser alarm system is relatively easier as the laser and the receiver can be setup in one box, on a single power input.

Do you need a black box for a laser alarm?

A laser beam system is easier to setup, either as a single or a separate entity. If a single box is maintained to setup the alarm, then it is to be made sure that the photodiode can’t have direct contact with the laser beam. Assembling the components and the circuit in a breadboard, it should be mounted in a black box having a hole.
