In 2010, Steve established Beijing LSJ Technology Development Co., Ltd in Beijing, committed in manufacturing and researching the emergency rescue devices.
On April 20, 2013, our staff carried radar life detectors and various rescue equipment on their shoulders and trekked more than 50 kilometers in one day and night to reach the front line of rescue with local firefighters.
On December 20, 2015, The Xili Squadron of Nanshan Fire Rescue Brigade in Shenzhen city successfully rescued the only survivor using the radar life detector provided by our company.
In 2016, CE, ISO9001, ROHS, and MSDS certificates were approved. 35+ patents were applied. Meanwhile, LSJ was invited to present and demonstrate our company's multi-modal composite life detector on CCTV. LSJ has been a leading entity in the rescue industry.
Our tech team promptly arrived at the disaster site with radar life detectors, pinpointing the trapped victims' location and aiding in the successful rescue of three individuals.
he first crafts top-notch products like ultra-wideband life-detection radars, multimodal life detectors, through-wall radars, micro-vibration life detectors, audio-visual life detection systems, firefighting thermal imagers, laser night vision, circular synthetic aperture radars, deformation monitoring radars, laser displacement monitors, and sonar life detectors. The second line develops elite products for defense, such as chemical agent detectors, portable multi-function high-risk environment detectors, and gas monitoring devices. These lines underscore our drive for pioneering life-saving and safety technology.
In 2022, following a 6.8 magnitude earthquake in Sichuan, our company promptly sent a skilled team with cutting-edge slope radar monitoring equipment from Changsha, Hunan, to the frontline of disaster relief. There, they provided continuous surveillance of the slopes over the rescue area, yielding significant outcomes and robust data support for the firefighting and rescue operations.
On February 6, 2023, our rescue team rushed to the disaster area with search and rescue equipment such as radar life detectors and audio-visual life detectors, and actively participated in the search and rescue of lives, which fully embodies the spirit of a great power.At the same time, in order to promote the positive and rapid development of the rescue cause, our company organized the donation of life search and rescue equipment, which fully embodies the social responsibility of enterprises.
On January 28, 2024, following a disaster, our engineers were first on-site with our proprietary portable circular synthetic aperture radar, swiftly setting up to monitor slope instability. They relayed crucial deformation data to the command center, ensuring the safety of the rescue teams. Major outlets like CCTV News, Xinhua News Agency, and China Youth Daily highlighted our data, featuring it in special reports.
our infrared thermal imagers, running rigorous quality tests. We're putting these devices through their paces with waterproofing checks and drop tests to ensure they can handle tough conditions. Temperature testing is also key, guaranteeing they perform well in extreme climates. Our commitment is to deliver high-quality, reliable tools you can trust in any situation.
