Laser through-beam alarm, abbreviation: laser through-beam or laser detector; Viandas series of laser intrusion detectors include through-beam laser detectors, reflective laser detectors, network-type laser through-beam detectors, and portable laser through-beam Detector, lighting type laser through-beam detector, uses 808nm invisible laser as the light source, and works in the way of unilateral emission and unilateral reception; among them, the alarm trigger mode of the laser detector with more than two beams can be through the switch of the detector. It is the first in the world to choose single beam blocking alarm or adjacent double beam blocking alarms at the same time. Therefore, it can be widely used in various complex environments and completely eliminate false alarms caused by small animals or other environmental factors.
As a highly concentrated light source, laser was used in aerospace and military facilities in the early days. The Viandas series of laser intrusion detectors use military-grade laser emitting and receiving devices as the main components of the detector, so that the product can be detected at a distance. Anti-interference and stability are superior to traditional active infrared through-beam, infrared grating and other detectors in all aspects. Therefore, it has been widely used and affirmed by users from all walks of life once it was launched. It has been successfully applied to airports, subways, national borders, and large-scale projects. Key equipment protects airports, various training grounds, factory perimeters, farms, etc. It is an important intrusion detector in the modern security field.
