About Four Dimensions Johnson Security


Dr Wang Yan, the Founder and CEO of FD, is considered, in China, to be an automotive expert, he has been associated with the industry for more than 20 years. In 1996, Dr Wang Yan spotted a business opportunity in the CIT vehicle industry. Certain financial institutions in China were outsourcing their cash transportation to professional security companies. Besides, the number of robberies in CIT vehicles had increased. Both of these factors represented an opportunity for that line of business and Wang Yan was ready to invest. Just like the Chinese automobile industry in the early 1990s, the CIT industry was in its infancy, with limited technology and production experience. To overcome these disadvantages, Wang Yan decided to enter the CIT vehicle industry through a joint venture (JV) with a foreign company that was already a market leader. Dr Wang Yang could offer the potential partner access to the Chinese market and, in return, FD could get access to its technology and know-how. After evaluating a few options, WANG chose JOHNSON as his partner for the JV.

According to the JV agreement, FD became JOHNSON’s exclusive partner in Asia. Furthermore, JOHNSON committed to continuously update product designs to maintain FD–JOHNSON’s technology advantage.

Unlike other Chinese CIT vehicle manufacturers that produced low-end CIT vehicles, FD–JOHNSON decided not to target sales to financial institutions, the largest customer group in the Chinese CIT vehicle industry at that time. Instead, FD targeted professional valuables escort companies, which provided transportation and custody of cash and other valuables for financial institutions. Financial institutions running their own CIT vehicles required multi-use vehicles, and their purchasing decisions were mostly driven by price. Professional value escort companies bought high-quality CIT vehicles because of the high level of risk involved in their business; therefore, safety and quality were the determining factors in their purchasing decisions. Meanwhile, professional value escort companies emerged as a blossoming sector in 1997, when Shenzhen Vpower Finance Convoy Co., the first professional security company in China, was established by 17 financial institutions.

In 2004, FD became the majority shareholder of JOHNSON, holding 63.07 percent of the shares. Three years later, in June 2007, FD purchased the remaining shares, becoming the sole owner of JOHNSON.


In order to meet the special requirement for SARS vehicles, KFB Extramobile GmbH incorporated a highly-efficient pressurised filter system combined with a ventilation system. The inserted filters guarantee that the contaminated interior air is transferred 99.99% particle-free to the outside and the interior is supplied with sufficient conditioned fresh air.

This new Ambulance concept became incredibly relevant for the Chinese market which was suffering from serious on-going epidemics. In total 235 vehicles were ordered to assist China to support the Healthcare actions.

FDJI recognized the potential in KFB-Extramobile and bought the company in 2010 with the view to developing opportunities in China, they have since become one of the main suppliers of Ambulances in China.
