1998, Top-arm established
Apr. 1999, assigned as ODM manufactory of one of Japanese top brand
Jul. 1999, assigned as ODM manufactory of one of Taiwan top brand
Apr. 2001, became the first China enterprise with the R&D manufacturing capability of PIR and Microwave dual-tech detector, broke foreign manufacture’s monopoly of dual-tech detector, and filled up the vacuity of this field in China
May 2001, successfully launched the first dual-frequency modulation photoelectric beam, compliant with world advanced class
Apr. 2002, innovatively designed Infrared Low-frequency Detection Technology-3D+2S
Apr. 2002, developed IRC Dual-tech Auto Shift technology which is applied to DT220 series products. IRC detection method broke the concept that the traditional dual-tech detector alarms depending on PIR and Microwave element detecting the intrusion signal simultaneously. IRC technology can detect the working status of PIR and microwave then judge through advanced proportion verifying. When one of dual-tech is disable, the IRC can automatically shift to another detection technology and keep the detector working continually
Jun. 2002, IRC technology was improved by China Patent Bureau, then obtained the patent certificate.
Jul. 2002, Top-arm detectors were exported to Europe market. Up to day, millions of Top-arm detectors have been deployed all over the world
Apr. 2003, the DT200 Series products with IRC technology were authorized as the High New-tech Project by Shenzhen Science Technology Bureau. After being tested by market, the excellent quality is widely accepted by customers
Jul. 2003, Top-arm became the first enterprise whose full range products comply with China Compulsory Certificate (CCC)
Sep. 2003, Top-arm became the first China enterprise who successfully developed EDC recognition technology used in quad photoelectric beam detector. EDC technology can discriminate the interferences from the second part transmitter or environment, to drastically improve the anti-interference capability against intentional damage, mask and environmental disturbances etc.
Jan. 2004, Top-arm became the ODM supplier of one of Germany top brand in the product of active infrared detector. Being approbated by Germany company, well-known in strict quality control, shows the Top-arm achievement in R&D and quality control capability
Jun. 2004, became the ODM supplier of one of American top brand, for tri-tech detector
Feb. 2006, developed successfully the patented microwave detection module based on Digital Phased Array Radar
Apr. 2006, firstly launched the unique microwave detector DT928 based on digital phased array radar. This detector firstly adapts MRD Driver detection technology. MRD Driver technology can hologram-scan the intrusion target, then trace and analyze its movement track to make an alarm decision. It can eliminate false alarms caused by environmental swinging objects such as trees and wet clothes etc.
Oct. 2006, launched the global-only detector A6(DT908) which is free of temperature and features full range anti-mask function
Mar. 2007, launched firstly the outdoor detector DT918 which can perform normally at harsh temperature ranged from -55℃ to +65℃. It is ideal for the outdoor application for environmental extremes such as oil field, coal mine and military etc. It is successfully used for military facility in the Arctic
Apr. 2007, assigned as the sole supplier of PIR and microwave detector for the China Certification Center for Security Products of Ministry of Public Security
Jan. 2008, assigned as ODM supplier of one Italy well-known Brand, for products of outdoor detectors. Top-arm outdoor detectors were widely exported to Europe market in large quantity
May. 2008, successfully developed digital wireless transmitter
Aug. 2008, successfully developed IP Network Alarm Module TIP-01
Feb. 2009, successfully partnered with one of American top brand, became the ODM supplier in photoelectric beam products
Jun. 2009, successfully launched outdoor Microwave Barrier, became the first manufacturer of such detector in China
Aug. 2009, successfully partnered with a Japan well-known photoelectric beam manufacturer, assigned as its ODM supplier of PIR and tri-tech detector
In 2010, Top-arm microwave perimeter barrier was successfully assigned as the special perimeter security product for Shanghai Expo 2010.
In 2012, Top-arm launched a new generation active radar sensor DM520 based on the solution of dual microwave radar and powerful fuzzy logic analysis. It can precisely calculate the Instantaneous Distance from sensor to target, absolute RCS, and displacement information and completely settle the troubles with the faults of traditional sensor. So the DM520 can quickly and efficiently distinguish a real intrusion target from various interferents under complicated environment.
Apr. 2013, Top-arm took part in the R&D team of an enterprise who is listed in TOP 100 global corporations
Jun. 2014, thanks to OEM cooperation, Top-arm added again a new series of products into the products line of a famous security brand who is listed in TOP 100 global enterprises. That is to say, Top-arm's product quality, and the standards of production & management are approbated again by the international famous brand. By pursuing excellence and keeping on innovation, Top-arm is always dedicated to supply trustworthy products for our global customers
