With the emergence of mobile surveillance technology, early market applications were limited due to factors like cost and network bandwidth, failing to meet expectations. However, the arrival of 3G and 4G technologies has opened up unprecedented opportunities in the field of mobile monitoring. It's time to focus on this growing sector, as 3G has ushered in a new era for mobile surveillance, with promising future development.
In January 2009, the Ministry of Industry and Information Technology issued 3G licenses to the three major operators, marking China’s entry into the 3G era. These operators began offering wireless video surveillance services, integrating video and alarm functions through their own 3G networks. This brought people a new experience in wireless video surveillance. The high bandwidth of 3G meets the needs of video transmission, making it a key feature for long-range and wide-area surveillance.
The mobility and high bandwidth of 3G will promote deeper integration between security monitoring and mobile communications. Surveillance is evolving from analog to digital, and then to wired and now wireless solutions. As 3G network speeds improve, more areas and users who previously didn’t need mobile surveillance can now benefit from it. Looking ahead, 3G-based wireless video applications are expected to become even more widespread.
Even more exciting is the introduction of 4G, which started pilot programs in cities like Guangzhou and Hangzhou, expanding bandwidth capabilities for mobile monitoring. Like fixed systems, wireless mobile monitoring will move toward high-definition, with H.264 High Profile encoding helping reduce bandwidth usage while maintaining image quality. However, despite 3G and 4G support, challenges remain—especially since these technologies are still in early stages.
Current 3G video terminals are not fully optimized for surveillance. For example, front-end storage devices are too large, making installation difficult. These issues require further technological improvements. Additionally, there are no unified industry standards, limited 3G coverage, and insufficient base stations in some regions, all of which hinder growth.
Miao Wei, Minister of Industry and Information Technology, noted that China’s broadband technology still lags behind global averages. However, fiber access is part of the "Twelfth Five-Year Plan," and broadband expansion is expected to accelerate, with lower costs and better coverage.
The Ministry of Industry and Information Technology also announced plans to speed up informationization, including the "Broadband China" strategy and IPv6 trials. These developments are positive for wireless mobile surveillance.
As communication technologies advance and network environments improve, wireless mobile video surveillance is set to enter a new phase. Its flexible nature makes it ideal for remote or temporary locations where traditional cabling is impractical. In applications like public transport, law enforcement, and emergency response, mobile surveillance offers unmatched advantages.
We’ve seen rapid improvements in mobile monitoring technology. Modern cameras now have night vision, longer range, and better performance. For instance, infrared laser-equipped police vehicles can monitor up to 400 meters.
Mobile surveillance is used by enterprises, industries, and individuals. The civilian market holds huge potential, especially in transportation, law enforcement, and personal security. As technology matures and costs drop, the mobile monitoring market is poised for growth.
Take bus surveillance as an example. Cities like Shenzhen and Guangzhou have installed thousands of mobile cameras on buses, connected to public security systems. With over 100,000 buses in just nine major cities, the market potential is enormous. Similarly, taxi surveillance is gaining traction.
Law enforcement vehicle monitoring is also rising. In Guangdong, over 70% of police cars must be equipped with mobile video systems. This trend is likely to expand nationwide.
Will mobile monitoring eventually replace fixed or IP-based systems? Only time will tell. But one thing is clear: mobile monitoring is becoming a key player in the surveillance industry. It combines wireless technology with traditional security, offering real-time, flexible, and efficient solutions. Whether through mobile phones, law enforcement vehicles, or handheld devices, mobile monitoring is shaping the future of surveillance.
