The sensor uses Active Infrared Sensor technology to detect both movement and human presence, ensuring that the door opens and closes at precisely the right time while reducing the risk of collisions during operation.<\/p>\n<p>Unlike many conventional <a href=\"https:\/\/sonha.com\/en\/nabco-automatic-door-sensor\/\">automatic door sensors<\/a> that perform only a single function, N-Search integrates both Motion Detection and Presence Detection into one device. As a result, the system not only detects approaching pedestrians to activate the door but also keeps the door open whenever a person or object remains within the protection zone.<\/p>\n<p>In addition, N-Search allows the detection area to be adjusted flexibly to suit different installation conditions, making it ideal for facilities with heavy pedestrian traffic such as hospitals, airports, hotels, and shopping malls. This technology provides the foundation for <a href=\"https:\/\/sonha.com\/en\/automatic-door\/?_brand=nabco-japan\">NABCO&#8217;s automatic door<\/a> sensors to meet demanding requirements for safety, detection accuracy, and operational efficiency simultaneously.<\/p>\n<figure id=\"attachment_21152\" aria-describedby=\"caption-attachment-21152\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-21152 size-full\" title=\"C\u1eeda t\u1ef1 \u0111\u1ed9ng NABCO \u1ee9ng d\u1ee5ng c\u00f4ng ngh\u1ec7 N-Search n\u00e2ng cao \u0111\u1ed9 an to\u00e0n\" src=\"https:\/\/sonha.com\/wp-content\/uploads\/2021\/06\/cong-nghe-n-search-cua-nabco.jpg\" alt=\"C\u1eeda t\u1ef1 \u0111\u1ed9ng NABCO \u1ee9ng d\u1ee5ng c\u00f4ng ngh\u1ec7 N-Search n\u00e2ng cao \u0111\u1ed9 an to\u00e0n\" width=\"1200\" height=\"674\" srcset=\"https:\/\/sonha.com\/wp-content\/uploads\/2021\/06\/cong-nghe-n-search-cua-nabco.jpg 1200w, https:\/\/sonha.com\/wp-content\/uploads\/2021\/06\/cong-nghe-n-search-cua-nabco-300x169.jpg 300w, https:\/\/sonha.com\/wp-content\/uploads\/2021\/06\/cong-nghe-n-search-cua-nabco-1024x575.jpg 1024w, https:\/\/sonha.com\/wp-content\/uploads\/2021\/06\/cong-nghe-n-search-cua-nabco-768x431.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-21152\" class=\"wp-caption-text\"><em>NABCO automatic door equipped with NABCO N-Search technology for enhanced safety<\/em><\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"What_makes_NABCO_N-Search_technology_different\"><\/span>What makes NABCO N-Search technology different?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The uniqueness of NABCO N-Search technology is not simply the addition of another sensor, but its ability to integrate multiple safety functions into a single device, significantly improving pedestrian detection accuracy while ensuring stable operation of the entire automatic door system.<\/p>\n<p>N-Search utilizes Active Infrared Sensor technology while integrating both Motion Detection and Presence Detection.
