20km long-distance wifi module wireless video surveillance intelligent robot wireless transmission, with the development of the economy, accelerating urban construction, resulting in dense urban population, the increase in floating population has led to the increase in traffic in urban construction, social security, prevention in key areas and other cities management issues. Especially in recent years, facing the new issue of urban counter-terrorism, new challenges have been raised to public security management, especially crime prevention and law enforcement. The increase of public security police is far from meeting the actual needs. Therefore, urban security image monitoring, which transforms scientific and technological means into direct combat effectiveness, has become an important means to solve the problem. Driven by the urban safety environment, the 20km long-distance wifi module wireless video surveillance system in the safe city came into being.
