Tengzhou Feitian Laser Automation Technology Co., Ltd. is a scientific research-based enterprise specialized in development, production and sales of laser photoelectric detection system. With experience in design and equipment manufacturing over 11 years, by virtue of the strong talent, advanced technology, efficient management and excellent service, we have been among leaders of domestic security and alarm industry. In 2010, we introduced brand strategy and started up two brands of "Feitian Laser" and "FETNLASER", striving to make them worldwide brands in high end laser photoelectric application industry within 10 years. Feitian Laser has strictly implemented ISO9000 system and CE certificate and continuously developed and researched new products leading by science and technology. Our products mainly are "high end", "precise", and "sophisticated" ones including various series of laser perimeter alarm systems, laser intrusion detectors, laser over-high, over-speed and crossing-line detection systems, laser photoelectric switches and laser detection and automation systems. They have been successfully used in industries such as railway, road, urban overhead road, military agency, petroleum and chemical, electricity, higher school and civilian industries. Feitian Laser intrusion detector (laser beam bijection alarm device) remedies the shortcomings of infrared alarm device. Compared with electronic fence, it is easier to install and maintain, with concentrated beam and strong penetration to realize super long distance (>1000m) transmission. Laser resists any interference from natural environment, with good confidentiality, which is suitable for alert deployment by invisible light. Enclosures of the equipment are anti-blow and anti-hit, IP67 rated, completely suitable for use in wild, outdoor and indoor environment. Our newly developed explosion proof laser beam is ExibmbIIBT4 Gb rated, suitable for perimeter alert areas with higher rated protection such as petroleum exploitation, petroleum refining, oil transport system, natural gas station, chemical plant and other areas with specific explosive gases.
