What is special about the laser detector? Why is the laser beam shot ten times more expensive than the infrared beam?

Both the laser beam detector and the infrared beam detector are perimeter intrusion security alarm systems, one is a laser-based beam-based alarm, and the other is an infrared-type villa as a light source. For two parts, one transmits one reception, and the middle beam establishes a warning line. If someone enters, the beam will be interrupted and an alarm will be triggered. Although the laser beam and the infrared beam are similar, they are not a product. The laser energy is much stronger than the infrared light, and the transmission attenuation is small. It has good stability and penetrating power and is highly resistant to many bad weather. Force, can effectively avoid the occurrence of false positives, is now an important part of the perimeter security alarm series products,

The use of some users will be very doubtful, since infrared radiation and laser radiation are all part of the series of security alarm system, only the source of the emission is not the same, why the price difference is so much, because the core function only sees the emission The light source is different, but in fact there are many different differences between the laser detector and the infrared detector. What is the difference? Let's take a look.

First, the emission source is different, this is also the source of the main gap in performance. The laser detector uses the world's most energetic light - laser, with stronger penetration and smaller divergence angle, and infrared The infrared detector is used for the detector, which is much inferior to the laser in terms of accuracy, beam concentration and penetration.

Second, the shell material is different. The laser beam detector uses a super-strong stainless steel casing, while the infrared beam detector uses a plastic casing, which is also superior in laser adaptability to environmental adaptability.

Third, the detection distance is different. The maximum distance of the laser can be as high as 5,000 meters, while the farthest distance of the infrared beam is only two or three hundred meters. In terms of distance, it determines the difference in the use of the two.

Fourth, anti-aging. Since the laser detector is made of stainless steel, it will still be stable under harsh conditions, but the outer casing of the infrared detector is used as a plastic material, which is obviously affected in the harsh environment, and Working at high temperatures can also affect the accuracy of infrared detectors.

Fifth, the working environment is different. The working temperature of the laser detector is between -55 °C and +70 °C, while the operating temperature of the infrared detector is between -20 °C and +55 °C.

Sixth, the number of beams is different. The laser beam detector has a maximum beam record of 36 beams, and the device has a net guard height of 6 meters, while the infrared detector can mount up to four beams with a height of 35 cm.

7. The scope of application is different. The laser detector is suitable for a variety of harsh environments, and can be installed indoors, outdoors, in the field, remote distance, flammable and explosive. Due to its own limitations, infrared detectors are only suitable for installation at the entrances and exits of various community factories and on the fence.

Combining these seven differences, is it possible to deduce why the price of the laser beam detector and the infrared detector is so large? Although the laser detector is innovatively developed on the basis of the infrared detector, it can be regarded as a breakthrough to transform the shortcomings and drawbacks of the infrared detector into the laser detector. advantage.
