Do security lasers exist? This is a question that has fascinated the minds of many people, most especially those who have watched spy movies or action films. For years, lasers have been used in various settings, from high-tech laboratory equipment to the laser pointers used in presentations. So it’s no surprise that many people wonder if they can be utilized for security purposes.
Well, the answer is yes! Security lasers do exist, and they are being implemented in various high-security settings around the world. Laser-based security systems are becoming more and more popular due to their accuracy and efficiency in detecting intruders. These systems work by emitting a beam of light that is invisible to the naked eye but can be detected by sensors. When the beam is interrupted, the system sends an alert to the security personnel that someone or something has breached the perimeter.
The technology behind security lasers is quite impressive. Not only are they highly sensitive to movement, but they can also differentiate between intentional and accidental interruptions. This means that even if a bird flies through the beam, the system will not trigger an alarm. While they may not be as flashy as the lasers seen in the movies, security lasers are definitely a game-changer in the field of security and surveillance.
How Security Lasers Work
Security lasers are used for perimeter protection around high-value properties and sensitive areas like military bases and prisons. These lasers are an advanced form of security systems that emit a beam of light to detect any movement or break-in attempts. Once the beam is breached, an alarm goes off, and the security personnel is alerted. In this section, we will explore how security lasers work to provide tight-security around the perimeter.
- Emitter: The emitter is the device that emits the laser beam. These beams are typically invisible, and the emitter is placed in a position where the beam is parallel to the ground to create a “fence” of light around the perimeter. The emitters are usually placed close together, so any attempts to breach the perimeter are immediately detected.
- Receiver: The receiver is another component of the security laser system that is positioned opposite to the emitter, around the perimeter. The receiver detects any changes in the laser beam’s properties, like intensity or wavelength, and sends this information to the central control unit.
- Control Unit: The control unit is the brain of the security laser system, where all the information from the receivers is processed. The system is calibrated to ignore any small movements, like animals and vegetation, and only alert the system when significant movements or attempts to breach the perimeter are detected. The control unit is also programmed to take into account the environmental factors, like wind and weather conditions, to minimize any potential false alarms.
The security laser system can work twenty-four hours a day, seven days a week, without the need for breaks or downtime. Furthermore, these systems are highly adaptable, and the control unit can be programmed for different scenarios to fit the needs of the particular perimeter, and security level required.
There are different types of beams used in security lasers, such as infrared and ultraviolet rays. The wavelength of the beam is carefully chosen to avoid the risk of eye damage and to minimize its interference with other optical devices.
To summarize, security lasers are an efficient and effective way of protecting valuable properties and sensitive areas. They work by emitting beams of light around the perimeter, which are then detected and analyzed by highly advanced control units. Any attempts to breach the perimeter are detected and instantly alerted to the security personnel to act accordingly, making security lasers a highly reliable form of protection.
