Eliminate misunderstandings and promote strong development of network monitoring market

The industry expects that the sales growth of network video surveillance equipment will exceed 25% in 2012, and the demand for video surveillance equipment is maintaining a strong development trend. At the same time, there are some misunderstandings in network monitoring applications that we need to point out.

The Network Video Surveillance Market Maintains a Strong Development Trend The fastest-growing (in terms of sales revenue) vertical markets will be transportation, urban surveillance and government markets. Different geographic regions will vary, but it is expected that all vertical markets will grow by more than 15% in 2012. The shift from analog products to IP-based surveillance products has promoted the monitoring market after the economic crisis in 2008 and will also promote sales growth in 2012.

After 2008, the global analog market was relatively sluggish, and the online video surveillance market grew almost three times faster than the market in 2010, an increase of more than 30%. “This trend has continued throughout 2011, with simulated equipment sales bleak, while online video surveillance vendors have shown strong sales performance,” senior market analyst Blake Kozak said. “In 2012, the global video surveillance equipment market is expected to Continue to maintain the growth trend, of which the continued strong growth of network video surveillance equipment will come out on top."

The price competition/commodification of the low-end analog surveillance market is becoming increasingly fierce. As the price of IP video decreases, smaller end users will find more value in the use of IP systems. "It is expected that the price reduction of IP cameras will reduce the price gap between IP and analog systems," according to Frost & Sullivan's "Video Surveillance Market in Asia Pacific" report: "More and more from China and Taiwan. The low-cost products will further drive down prices, and the economic downturn will force companies to offer more competitive prices."

Seven Mistakes in Network Monitoring Applications Network Video Surveillance is IP Surveillance. IP is the abbreviation for Internet Protocol. It is one of the most commonly used protocols for communicating through computer networks. Network video surveillance is the transmission of digital video information over wired or wireless IP networks. As long as the network is reachable, video monitoring and recording can be realized, and this monitoring can also be perfectly combined with many other types of systems. With the increasing application scope, there are more and more errors in the application of network video surveillance.

Myth # 1: Transmission of video on the Internet is not safe enough. Fact: Although the original purpose of the network was to make the information public enough, it can be used as long as the proper security measures are adopted, such as firewall, VPN, or password protection technology. To transmit some highly sensitive information.

Myth #2: If all video information is transmitted over the network, it will not cause network congestion or even crash. Fact: If only a few monitoring points are available, the existing Fast Ethernet (100Mbit) can meet the transmission needs. Bandwidth requirements. The user can adjust the bandwidth according to the compression ratio and the frame rate. If it is multiple monitoring points, we recommend that you have a dedicated network line. This is quite similar to rail transit. Once the existing rail line becomes congested, it will have to build new rail lines to ease the tension on the line. Moreover, for large-scale enterprise applications, the local network is usually a gigabit LAN. Using switches and routers, the network can be divided into different network segments.

Moreover, the intelligent function of the network camera can already choose whether to send video according to conditions such as event triggering, dynamic detection, and preset time. The amount of video information that needs to be transmitted is not too much. Almost 10% of the time it takes to transmit information, and no video information is transmitted on the network in 90% of the time.

Myth #3: I'm installing an analog surveillance system and I don't have any IP monitoring. Fact: Perhaps DVR providers want people to believe this, but in fact, the development of video server technology has bridged the gap between analog surveillance and digital surveillance. The insurmountable gap. Just connect the analog camera to the video server, and then convert the video signal collected by the analog camera into a digital signal and transmit it on the network. In other words, the video server allows the analog camera to have the function of a network camera. In fact, for most users who already have analog surveillance systems, they prefer to choose their own way to build their own IP surveillance systems, or hybrid IP surveillance systems consisting of network cameras and video servers. In short, your existing analog surveillance system will never stop you from moving toward IP monitoring.

In fact, many banks and some financial institutions use the Internet to handle some global financial things. There is no doubt that it must also be a reliable medium for security surveillance and remote monitoring. Compared with digital surveillance, the confidentiality of analog surveillance is much worse, and it has almost no confidentiality. Anyone can see these so-called security information under the simulation system, and even tamper with this information, causing huge losses. IP monitoring will never happen.

Myth 4: The network video is not as clear as the simulation. Fact: The real-time monitoring effect of the network camera is exactly the same as the video playback effect. Of course, the image has undergone digital compression processing, and the effect is slightly less than that of the unprocessed analog signal. The traditional hard disk recorders are inconsistent with the monitoring and playback effects. Since the signals are directly transmitted during monitoring, the effect is good, and the playback results are also compressed. The effect depends on the compression technology used by different manufacturers. Moreover, with the development of technology, network cameras and IP monitoring technologies can reach megapixel resolution, and analog cameras can only reach a resolution of 40,000 pixels at most because of their technical limitations.

Myth #5: Network cameras are much more expensive than analog cameras. IP surveillance is too expensive. Fact: In terms of price, network cameras are more expensive than analog cameras. However, you should also see that its functions are analog video cameras, analog signal digitization, video compression transmission, and intelligent control functions. Compared to all costs of monitoring systems based on DVR architectures, IP monitoring is cheaper than it is. For an analog system, it's not that you buy a DVR and it's all okay. You also have to purchase a lot of related equipment such as a large number of analog video cables. Moreover, if you want to achieve PTZ control, you also need to lay a lot of additional video cables, and PTZ function in the IP monitoring is still achieved through the network cable, and does not require additional cables.

Myth No. 6: If network congestion occurs or even suddenly breaks, IP monitoring will suddenly collapse, so it is unreliable. Fact: The IP network architecture was able to provide redundant backup functions in the early 1960s and early 1970s. It has always been a huge demand. As of today, various storage servers, network switches, and optional routers have been providing such simultaneous backup functions. The function of the storage server is to ensure that after offline, it is convenient to call data. The application of backup power supply, hot swap RAID disk, fault-tolerant storage, and dual network adapters can help implement the redundancy backup function. Although a small network structure may not require all of these complex security measures, choosing a high-quality IT component is in any case much more reliable than a traditional CCTV solution, a VCR or a DVR, and is urgent in the event of a problem. Processing is also much less time consuming than DVR solutions.

Myth #7: IP monitoring is good, but it seems to be a long way away from us, at least for 5 years. Fact: It seems that the time when IP monitoring is not used is the crux of all problems! Let us explain with specific data. Since the launch of the first network camera in 1996, 200,000 network cameras have been successfully sold and installed, and this number is also rising rapidly year by year, which fully demonstrates that people’s interest in IP monitoring is also increasing. Because people gradually found that, whether it is from the price or reliability or any other point of view, IP monitoring has proved to be suitable for both the present and future-oriented mature solutions.

Here, we have uncovered many misunderstandings and misconceptions that have surrounded IP monitoring. We hope that people can see that IP surveillance is a mature solution that is highly scalable, effective, and efficient.
