The wireless monitoring security market is experiencing explosive growth, driven by the cost-effectiveness of wireless infrastructure compared to traditional cabling solutions. According to Josh Woodhouse, a video surveillance analyst at IHS, wireless systems offer an affordable way for customers to set up monitoring networks. In regions with well-established surveillance systems, such as the U.S. and the U.K., wireless adoption is steadily rising. However, emerging markets without existing infrastructure are expected to see the strongest growth in the coming years, fueling the expansion of the wireless surveillance market.
As a foundational element of the Internet of Things (IoT), the security monitoring industry is poised for significant development. Technologies like digital, analog, and HD-SDI are continuously improving, giving users more choices. With advancements in algorithms, intelligent analysis is now being integrated into real-world projects, especially in image diagnosis, retrieval, and detection. By 2012, China’s security industry had reached a total output value of approximately 325 billion yuan. With new policies in place, the Chinese security market is projected to grow by 30% annually. Applications in finance, public safety, transportation, healthcare, education, culture, technology, communications, energy, and enterprises will expand further, creating substantial opportunities in the civilian security sector.
Intelligent video surveillance has become a powerful tool for companies aiming to dominate the security market. The success rate of video search exceeds 99%, while smart video recognition rates surpass 90%. Daytime accuracy is over 90%, and nighttime accuracy remains above 80%. Nearly 400 cities have already implemented smart city initiatives using these technologies.
Telecom operators are also entering the IoT-based home security market. For example, China Telecom launched the "Global Eye" service, which supports both industrial and home surveillance. It also introduced "3G Smart Butler" for smart homes, enabling mobile phone control of door sensors, infrared detection, gas monitoring, and video surveillance. Similarly, China Mobile offers the "Livable Pass" service, allowing users to monitor their homes with features like anti-theft alarms, fire alerts, and elderly assistance.
Wei Wei, Dean of the School of Electronics and Information Engineering at the University of Science and Technology, noted that wireless surveillance solutions now support standard definition images via 3G, with options for high-definition resolution ranging from QVGA to 1080p. As 4G technology becomes more widespread, wireless surveillance will gain even greater capabilities.
4G technology significantly enhances wireless surveillance by offering faster transmission speeds and improved stability. Currently, 4G networks can achieve download speeds of up to 100 Mbps and upload speeds of 20 Mbps—ten times faster than 3G. This bandwidth is sufficient for 720p high-definition monitoring, which typically requires 2–4 Mbps. If 4G is widely adopted in China, devices based on 2G or 3G networks may gradually fade from the market. As a result, the security industry is likely to undergo significant upgrades and transformations.
Despite the potential, challenges remain. High data costs and varying operator packages make it difficult to promote wireless high-definition surveillance. However, 4G is being introduced gradually, with improvements built on 3G technology, which could reduce costs over time. Industry sources suggest that future 4G network fees may be lower than current 3G packages.
If 4G networks effectively address issues related to bandwidth, stability, and traffic costs, they could revolutionize high-definition surveillance. In short, the advancement of 4G technology will make wireless surveillance even more powerful and efficient, shaping the future of the security industry.
