In perimeter prevention and alarm applications, infrared emission was used earlier. Later, with the development of technology, infrared emission functions were improved and upgraded, especially the rise of laser detectors. Its extraordinary anti-interference ability, long-distance accurate detection, and lower false alarms, have attracted much attention in perimeter prevention applications.
So, what are the differences between these two products? Which one is more practical? The editor of Feitian Optoelectronics will take you to learn more about it.
In terms of detectors, the detection distance of infrared emission is generally 50-350 meters, which is suitable for some communities, campuses, factory parks, etc.; while the detection distance of laser emission detectors is generally around 100 meters-5 kilometers, which is suitable for substation , petrochemicals, railway cross-line detection and other occasions.
In terms of anti-interference, infrared emission has high requirements on the environment. If the installation is not standardized or is disturbed by branches, strong winds or other infrared equipment, false alarms are likely to occur. Of course, anti-interference design can be added to the shooting to minimize the false alarm rate. The laser is resistant to electromagnetic interference, with small divergence angle and strong penetration, greatly reducing the false alarm rate.
In terms of detection accuracy, infrared surfing generally reduces false alarms by adjusting the trigger time. Laser surfing uses special digital encoding and decoding technology, and cooperates with the equipment to block any beam alarm, adjust the trigger response time, and set a bypass mode. This can greatly improve the detection accuracy of laser surfing. At the same time, users can adjust more flexiblely when using it.
Based on the above information, it can be seen that laser counter-surveillance has more advantages and is more practical than infrared counter-surveillance. Although the laser counter-surveillance detector is innovatively developed based on the infrared counter-surveillance detector , it has also been regarded as a breakthrough, transforming the shortcomings and disadvantages of infrared counter-surveillance detectors into advantages of laser counter-surveillance detectors.
As soon as the laser injection product was launched, it has been fully recognized by the market and is widely used in key security protection places such as prison detention centers, airports, petroleum and petrochemicals, railways, electricity, finance, museums, and national defense. I believe that in the near future, laser injection may become the first choice detector for perimeter intrusion alarm systems.
