In recent years, the rapid development of smartphones like iPhones and Android devices has significantly enhanced mobile performance. This advancement has allowed manufacturers to upgrade traditional monitoring software, tailoring it for mobile use and enabling more efficient video transmission. As a result, mobile phone-based monitoring systems have become increasingly popular. Some companies have started integrating 3G wireless technology with mobile apps, allowing users to view remote video footage in real time. By combining the strengths of network monitoring, mobile surveillance offers new experiences for industry users, although early-stage challenges still exist.
Today, as electronic devices become essential in daily life, people often wonder what's happening at home when they're away. Remote monitoring provides a convenient solution, allowing users to watch live video from network cameras and even adjust camera angles or settings remotely. With computers and mobile phones becoming central to modern life, remote monitoring can now be controlled through these devices, making it an important tool for home security and elderly care.
It’s safe to say that network monitoring is now suitable for every household. The resolution of IP surveillance cameras plays a key role in image clarity. HD network cameras start at 720P, offering about nine times more pixels than CIF, while 1080i/1080P models provide up to 20 times the resolution. High-definition cameras are advancing rapidly, with some models already featuring over 10 million pixels. These improvements greatly enhance image quality, something traditional analog cameras struggle to achieve due to bandwidth limitations. Additionally, IP surveillance reduces cabling costs and allows multiple signals to be transmitted over the same network. The open nature of IP systems also enables flexible access to video data from anywhere, making it easier for users to manage. Storage requirements for high-definition video grow exponentially, so sufficient disk space is necessary. High-definition monitoring typically uses either centralized or distributed storage methods, with efficient compression helping to reduce data size.
Mobile video surveillance is now presenting new opportunities. Currently, China’s video surveillance market is mainly focused on government, public security, transportation, and other industrial sectors, with slower growth in personal or home use. Experts believe many small businesses and families have security needs, but existing solutions don’t fully meet those demands, which has slowed market growth. However, with the expansion of mobile broadband and the popularity of smart devices, along with efforts by service providers to promote personal video surveillance, consumer interest is expected to rise. In 2012, this sector began to see significant growth.
Many manufacturers are now entering the market, launching mobile video surveillance products. Companies such as Hand Vision, Portable Eye, Zhi An Bang, and Shen An have all introduced their own solutions. Despite this progress, front-end network cameras remain a major challenge. Traditional cameras can cause discomfort, and ease of use is still an issue. Most network cameras require customers to install them themselves and set up their own gateways.
The advantage of mobile monitoring is that users can view live footage and control PTZ functions anytime, anywhere, as long as they have a mobile signal. It supports 3G, Wi-Fi, and various operating systems like iPhone, iPad, Android, and Windows Mobile. The commercial scope of 3G networks is expanding, and wireless bandwidth has improved significantly. The application environment for mobile video surveillance is becoming more mature, allowing real-time viewing of remote content regardless of location.
Mobile video surveillance offers wide coverage, as mobile networks are not restricted by terrain or obstacles like mountains, rivers, or bridges. It is also cost-effective, eliminating the need for expensive long-distance cabling. Users can monitor remotely using just a smartphone, without needing a pre-installed computer client. Furthermore, it offers diverse services, covering fixed network monitoring and supporting mobile applications like law enforcement and interviews.
However, mobile video surveillance still faces challenges, particularly in terms of bandwidth and frequency resources. Public mobile networks have limited bandwidth per device, and they must handle voice, data, and other services simultaneously. Even with 3G, transmitting CIF-quality video may only support three monitoring points per base station. Wireless broadband involves shared resources, leading to unstable bandwidth and lower speeds. While 3G can reach up to 1 Mbps, it’s still much slower than wired connections, making it more of an auxiliary solution.
Wireless channels also have higher bit error rates, especially when devices are moving. Available bandwidth fluctuates, and high-bandwidth video data is prone to packet loss, reducing overall quality. High tariffs are another issue—wired transmission is generally more cost-effective than wireless, and broadband is even more so. Operating costs for 3G-based video surveillance include internet fees, mobile viewing charges, and system maintenance, making it difficult to reduce expenses.
Lastly, mobile screens often limit the sharpness of video surveillance. Due to screen size and resolution, details may not be clearly visible, which can hinder effective monitoring.
