4G Lets Wireless Surveillance Safeguard New Storm
In the context of the security industry, network-based surveillance has become a major trend. However, its market share remains relatively low. Industry experts suggest that this is due to an immature domestic network environment. At the same time, the rising demand for high-definition surveillance in China has become increasingly evident. Many well-known surveillance companies have started launching higher-resolution 700-line cameras, and some manufacturers have even introduced the first 10-megapixel cameras. As these high-definition front-end devices become more widespread, the pressure on back-end transmission systems increases significantly. This has led the industry to welcome the arrival of 4G networks.
Compared to 3G, 4G offers significant improvements in both transmission speed and bandwidth, along with greater stability. However, concerns about data usage costs remain a key issue. Since different operators offer varying packages, the cost of service can be quite high, which hinders the adoption of wireless high-definition surveillance. It is expected that the gradual rollout of 4G technology will reduce costs by building upon existing 3G infrastructure. According to reports, future 4G network costs are likely to be lower than current 3G package rates.
If 4G networks can effectively address issues related to bandwidth, stability, and traffic costs, the impact on HD surveillance could be revolutionary. In other words, the development of 4G technology will make wireless surveillance more powerful and efficient.
The rise of 4G has also given birth to mobile monitoring and video conferencing applications. High-definition video surveillance using 4G not only allows real-time image transmission but also maintains clarity when zooming in, greatly improving urban management efficiency. In contrast, 3G networks struggled to support large-data wireless applications due to limited bandwidth, poor resolution, signal interference, and long buffering times—factors that negatively affected user experience and market acceptance.
With the advent of 4G, this situation is set to change completely. Li Tiefeng noted that high-definition video-based applications are expected to become one of the core services of 4G, especially high-definition video calls. If pricing is reasonable, they could become a primary service for smartphone users. Additionally, government and enterprise sectors have shown interest in high-definition video surveillance. For example, Shenzhen TV has expressed interest in "photographing and transmitting" applications, while public security and traffic police departments are exploring collaborations with Shenzhen Mobile. Shenzhen Mobile’s proposed mobile video conferencing system has also been well-received during testing.
For regular users, Shenzhen Mobile has introduced traditional high-speed download, mobile video, games, music, reading, animation, and betting services. In addition, it has developed three interactive products tailored for 4G: 4G video area, 4G video calls, and 4G video on demand. These applications leverage the high-speed and stable nature of 4G networks. However, industry insiders note that 4G may lead to new models of mobile internet applications, and while high-definition video-based services could become core features, they still need to be tested through real-world use.
China Mobile recently announced the full-scale deployment of its 4G network. Compared to 3G, 4G offers much faster upload and download speeds. Starting from the second half of this year, the company launched its 4G network construction. This includes TD-LTE equipment procurement across 100 cities in China since 2013, with over 200,000 base stations deployed, including 180,000 new ones built in 2013. The total investment is estimated to reach around 18 billion yuan.
Industry professionals believe that 3G networks have limitations when it comes to implementing high-definition surveillance, whereas 4G networks effectively address these challenges. Song Yijun explained that according to current pilot tests, 4G network speeds are ten times faster than 3G, with download speeds up to 100 Mbps and upload speeds reaching 20 Mbps. Most 720p HD surveillance requires between 2-4 Mbps per channel, which 4G easily supports.
Another concern for consumers is the stability of 3G networks. Uneven distribution of base stations often leads to inconsistent signal strength, causing frame drops and screen freezes. However, as part of its 4G network expansion, China Mobile plans to build 180,000 new base stations in 2013, addressing signal coverage issues. Industry insiders believe that 4G will meet the requirements of third-generation networks in terms of coverage, communication quality, and multimedia transmission.
Finally, the cost of data usage remains a topic of concern. With varying packages offered by different operators, service fees can be high, making it difficult to promote wireless high-definition surveillance. However, the gradual introduction of 4G technology, based on existing 3G infrastructure, is expected to reduce costs. Reports indicate that future 4G network costs will be lower than current 3G packages.
Overall, the 4G network deployed by China Mobile is expected to bring significant breakthroughs in terms of stability and cost. According to industry sources, the impact of 4G on wireless HD surveillance is clear. If 4G can successfully resolve issues such as stability and traffic costs, its effect on high-definition surveillance could be truly transformative.
