Compared with the single function of common truck anti-theft products on the market, Antu Shield integrates multiple functions such as anti-theft oil, anti-theft car, anti-theft spare tire, anti-theft battery, anti-theft goods and GSM anti-theft alarm system for the first time to solve the overall security and anti-theft problem of trucks. Its wireless anti-theft fuel tank cover technology has won the national patent. If the fuel tank cover is opened illegally, it can trigger an intelligent alarm. Moreover, because it is wireless anti-theft oil technology, it will not cause the alarm failure like other anti-theft devices.
