Network monitoring into new favorite mobile applications have opportunities

In recent years, with the rise of smart phones such as Iphone/Andriod, the performance of mobile phones has been further improved. They can also be dedicated to the characteristics of the mobile video transmission of the original monitoring software for functional upgrades, so that it has the ideal mobile phone monitoring. Some manufacturers have started to combine 3G wireless video surveillance with mobile applications to enable real-time online viewing of remote video images. Integrating the advantages of network monitoring, mobile phone monitoring brings new experiences to industry users, but due to the early development, the development of mobile phone monitoring also faces some difficulties.

Network monitoring stands out Today, with the continuous development of technology, electronic products have become an integral part of people's lives. However, when you go to work and you want to know what happened at home, what to do? This will benefit from remote monitoring. The convenience. The so-called remote monitoring is to observe the live image through a network monitoring camera. It also includes the operations such as adjusting the direction of the camera and the daily settings of the monitoring camera. Now that computers and mobile phones have become the new darling of people, remote monitoring can control the home surveillance cameras through computers and mobile phones. This is one of the important means for theft and care for the elderly at home.

It can be said that network monitoring is suitable for each household. First of all, the resolution of the IP surveillance camera is the most important condition for determining the sharpness of the image. The resolution of the HD network camera is 720P at the lowest, and its number of pixels is approximately 9 times that of the CIF, and the number of pixels of the 1080i/1080P is approximately It is 20 times that of CIF. The development of high-definition network cameras can also be said to be a thousand miles, and products with 10 million pixels or more have also begun to show up in the surveillance industry. This plays an important role in improving the imaging quality of high-definition network cameras, and high-definition analog cameras are difficult to break through the bottleneck of transmitting video signals due to the wide video bandwidth. Secondly, the cost of cabling for IP surveillance is low, and multiple signals can be transmitted on the same network. The openness of IP systems also allows users to view surveillance video data in multiple ways anywhere. IP monitoring is plug-and-play, making it easier for users to use. The capacity of high-definition surveillance data storage media grows at a geometric multiple, and therefore requires more disk storage space as a support. High-definition storage can be roughly divided into centralized storage and distributed storage. High-definition monitoring systems transmit and store signals that are compressed and have high efficiency. '

Mobile Video Surveillance Facing Opportunities At present, China's video surveillance services are mainly concentrated in government, public security, transportation, electric power, petroleum, banking and other industrial users, and are slow to develop in personal/home users. Ma Yuting believes that many SMEs and families are not without security needs, but the existing security products and solutions do not meet these customer needs well, so the market scale has not yet formed. “With the rapid development of mobile bandwidth and the popularity of smart mobile terminals, and the cultivation of personal video surveillance market by operators, users will be more proactive in applying home video surveillance services. In 2012, this business entered a period of rapid development.”

It is understood that many manufacturers are now looking for business opportunities and have entered the market one after another. Hand Vision, Portable Eye, Zhi An Bang, Shen An, and others have all launched their own mobile video surveillance products.

However, for mobile video surveillance, the experience of the front-end network camera is the first and foremost problem: Traditional cameras often cause people's nervousness and resentment, and the ease of use of the device is more difficult to solve. Most network cameras require customers to install their own, and they must set their own gateway.

The advantage of mobile phone monitoring is that whenever and wherever the user is, as long as the signal of the mobile phone can be monitored in real time and the front camera PTZ is controlled. Mobile phone monitoring support 3G, WIFI and other kinds of standard, support IPHONE4, IPAD, Android, WindowsMobile and other mobile operating systems. The commercial scope of 3G wireless networks is becoming wider and wider, and the bandwidth of wireless networks has also been greatly improved. The application environment of mobile video surveillance has become more and more mature. Mobile video surveillance can watch remote monitoring content in real time in any space and at any time.

Wide coverage: The wireless network coverage of mobile phones is very high, and is not limited by complex terrain and areas such as mountains, rivers, and bridges.

Low cost: It eliminates the high cost of long-distance network cabling.

Easy to monitor: You can use your mobile phone to perform wireless video surveillance anytime and anywhere. It is not limited to a computer that is pre-installed with a monitoring client.

Diversified services: Mobile phone monitoring can not only cover all fixed network monitoring services, but also can carry out various mobile services such as mobile law enforcement monitoring and mobile interviewing.

Mobile video surveillance faces difficulty in bandwidth and frequency resources: Since the effective bandwidth of a single terminal in a public mobile communications network is quite limited, it is often necessary to carry voice, data, and other transmission services simultaneously. Even if a current 3G network is used to transmit CIF images, one base station cannot More than three monitoring points, and wireless broadband is characterized by multi-user resource sharing, bandwidth uncertainty in the transmission, and broadband with the increase in the speed of the decline, the current speed of 3G network can reach 1M, only tens of times slower Bytes, so it can only be used as an auxiliary transmission means.

The bit error rate of the wireless channel is relatively high: especially when the terminal device is in a moving state, the available bandwidth and bit error rate index are greatly reduced, the available bandwidth fluctuates frequently, and the high bandwidth video monitoring data is prone to packet loss. Sex is not high.

High tariffs: Generally speaking, the cost-effectiveness of wired transmission is higher than that of wireless transmission, and broadband transmission is even more so. The operating costs of the 3G wireless video surveillance system include broadband Internet access fees for video sources, mobile viewing fees, monitoring system operating costs, etc. The total operating costs are high, and it is difficult to reduce.

Sharpness is not good: Video surveillance on a mobile phone is often limited by the size and resolution of the phone screen and may not be able to focus on the details of the screen.
