In recent years, the rapid development of smartphones like iPhones and Android devices has significantly enhanced mobile performance. This progress has enabled manufacturers to upgrade traditional monitoring software with features tailored for mobile video transmission, resulting in a more efficient and user-friendly mobile surveillance experience. Some companies have started integrating 3G wireless video surveillance with mobile apps, allowing users to view live footage remotely in real time. By combining the strengths of network monitoring, mobile surveillance offers new possibilities for industry users. However, due to its early stage of development, mobile monitoring still faces several challenges.
Today, with technology continuously evolving, electronic devices have become an essential part of daily life. When people are away from home, they often want to check what’s happening at their residence. This is where remote monitoring comes into play, offering convenience and peace of mind. Remote monitoring involves viewing live images through a network camera, as well as adjusting the camera direction and settings. With computers and smartphones becoming everyday tools, it's now possible to control home surveillance systems through these devices, making it a key solution for home security, elderly care, and theft prevention.
It can be said that network monitoring is becoming increasingly popular in households. One of the most important factors determining image clarity is the resolution of IP surveillance cameras. HD network cameras typically start at 720P, which has about nine times the pixels of CIF. Meanwhile, 1080i/1080P models offer up to 20 times the resolution of CIF. High-definition cameras with over 10 million pixels are now entering the market, greatly improving image quality. Unlike high-definition analog cameras, which struggle with video signal transmission due to bandwidth limitations, IP-based systems offer greater flexibility.
IP surveillance also reduces cabling costs and allows multiple signals to be transmitted over the same network. The open nature of IP systems enables users to access video data from anywhere, making it easier to use. Additionally, storage requirements for high-definition video grow exponentially, leading to the need for larger disk space. Storage solutions can be either centralized or distributed, with efficient compression techniques helping to manage large volumes of data.
Mobile video surveillance is currently facing great opportunities. While China’s video surveillance services are mainly used by government, public security, and industrial sectors, the personal and home market remains underdeveloped. Experts believe that many small businesses and families have security needs, but existing products don’t fully meet those demands. As mobile broadband improves and smart devices become more widespread, the home surveillance market is expected to grow rapidly. In 2012, this sector entered a period of accelerated development.
Many manufacturers are now entering the market, launching their own mobile video surveillance products. Companies such as Hand Vision, Portable Eye, Zhi An Bang, and Shen An have introduced various options. However, challenges remain. The front-end network camera experience is crucial, as traditional cameras can cause discomfort and are not always easy to use. Most require installation and configuration, which can be a barrier for some users.
Mobile phone monitoring offers the advantage of real-time access from anywhere, as long as there is a mobile signal. It supports 3G, Wi-Fi, and other standards, and is compatible with iOS, Android, and Windows Mobile. As 3G networks expand and wireless bandwidth improves, the environment for mobile video surveillance becomes more mature. Users can watch live feeds anytime and anywhere without being limited to a computer with a pre-installed monitoring client.
Other benefits include wide coverage, as mobile networks reach even remote areas, and low cost, since it eliminates the need for expensive cabling. It also provides diverse services, including mobile law enforcement and field interviews, expanding beyond traditional fixed network monitoring.
However, mobile video surveillance still faces challenges. Bandwidth and frequency resources are limited, especially in public networks where voice, data, and video must all be transmitted simultaneously. Even with 3G, only a few monitoring points can be supported per base station. Wireless networks also suffer from unstable bandwidth and high bit error rates, particularly when devices are moving. This leads to packet loss and poor video quality.
High tariffs also pose a challenge. Wired and broadband transmission tend to be more cost-effective than wireless options. Operating costs for 3G-based systems include internet fees, mobile viewing charges, and system maintenance—making them expensive to maintain.
Lastly, the screen size and resolution of mobile devices can limit the clarity of video, making it difficult to see fine details. Despite these challenges, mobile video surveillance continues to evolve and gain traction in both personal and professional applications.
