IP network camera market conditions and marketing strategies
Security monitoring system has not only complex wiring analog control system, but rely more on network video surveillance system. Through years of market cultivation, the network concept has been many system integrators and end-user acceptance and recognition. Network video surveillance market combined analog-based, most of the projects or the use of traditional analog cameras with digital encoder, pure IP product promotion is still facing all kinds of obstacles and difficulties.
IP Camera marketing differ from analog cameras, analog cameras networking is simple, many system integrators and engineering companies have sophisticated system solutions. IP network camera system solutions related to the forward network transmission, network planning, video storage, image, the image is displayed on the wall and many other issues, at the same time each network camera manufacturer-chip solution, the underlying control protocol, to the system interconnection caused great difficulties, IP network camera sales often need to provide customers with a complete system solution, so that a higher technical requirements for the manufacturers / system integrators.
The problems faced and the gradual maturity of the network market demand for IP product promotion, I combined with years of experience in marketing, to discuss the marketing strategy insights.
IP Camera industry customer base
The IP monitoring the advantage of the interconnection, remote monitoring, and flexible networking. Prescribe the right medicine, you need to identify the user groups. At present, the main network video surveillance market is concentrated in several major sectors of the government public security, telecom operators, financial, transportation, prisons, power, industrial enterprises, education. "Green City" project led by government agencies and public security, the majority expressly To select network monitoring. Financial and transportation industries in recent years showing a clear demand for networking, networking has undoubtedly become the first choice. The education sector due to the improvement of network infrastructure tend to network monitoring. The transportation industry is mainly concentrated in the port security card systems and electronic police system, this system is often a standard definition network camera or analog cameras in each lane are required to configure a video camera, license plate recognition is low, the number of cameras installed, the system cost is high . The introduction of high-definition network camera, a HD IP Camera can monitor multiple lanes, saving a number of cameras installed to improve the license plate recognition rate. Industrial enterprises and residential districts scattered, independent, less obvious characteristics of the industry, the product itself is weak, so the tendency is not so significantly above industry.
Different industries, the performance requirements of IP products. For telecom operators, IP network camera performance requirements are higher, related to more stringent conditions, such as Telecom Global Eye project is generally cheaper chain stores, shops, businesses, product prices, stable performance, simple device configuration, the general requirements to zero configuration, plug and play, with a private network traversal technology automatically registered in the telecommunications server, the telecom server to assign permissions to users to view real-time image and video information through the telecommunications network.
IP Camera marketing strategy
Needle sales for IP cameras, I think there are several points to note.
First, do a good job in key industries / brand finalists, particularly safe city, finance, telecommunications, mobile finalists, brand finalists to enter the industry threshold. Brand shortlisted projects are generally large-scale projects with high impact and visibility in the industry, IP network cameras point more, the amount is relatively large, good brand finalists work can be a breakthrough on a major project to enhance the brand awareness. Brand finalists just to enter the threshold for the industry, follow-up, there is much work to be done, the successful conclusion of the final signing of procurement contracts be considered brand finalists.
Second, the construction of a strategic partner. To form a broad strategic cooperation with many platform software vendors to form a strategic alliance to create a good ecological environment. Strategic cooperation in the platform software is mainly concentrated in carrier-class operating platform, the industry-level platform software vendors (financial, transportation, etc.) cooperation. IP network cameras provide total system solutions, system software functions to control in front of the camera selection is determined by the platform software is able to access the HD IP Camera, IP camera manufacturers to communicate well and domestic well-known platform software vendors, platform software docking work, to establish a close strategic partnership, to achieve win-win cooperation, to create a good ecological environment. Leveraging the platform software marketing network, IP network camera sales. Domestic carrier-class platform for software vendors ZTE, Huawei, China Star Electronics, mutual trust and exchange, Zhejiang letter production, ZTE peacekeeping force, LONDON force, Suzhou Keda, industry-level platform software vendors Sheng Yihua, Chongqing News United States, Xinyi Technology, Star Valley Technology, Hangzhou days as Guangzhou Jinpeng, Blue Star.
Third, market segments, develop key industries, focusing on public security, transportation, finance, telecommunications, prisons, oil, electricity, education. For these high-end industrial users, industry conference, the promotion will be targeted for technical exchanges, understanding of customer needs on the ground, providing system solutions that meet customer needs.
Fourth, the channel construction (agents and dealers), through the project agent, agent, customer resources through distribution market development and product sales. Channel agent can be combined with many partners to quickly dominate the market through the marketing network of strategic partners, and win market share. Of particular importance is that this is a win-win strategy, manufacturers with integrators, agents work closely together, sharing of customer resources, customer-facing common problems, discuss and handle customer needs. Channel construction, the choice of partners is particularly important, the partners must be a good match, the IP technical background, ability to provide system solutions, this will be long-term cooperation, the two sides can work closely to gain market share quickly.
Fifth, OEM / ODM construction. There are some companies may focus on system integration, will be relatively weak in terms of products, also want to be able to have their own brand, by the way of OEM / ODM cooperation.
Noteworthy part of
Traditional analog camera manufacturers to sell products without considering the basic multi-system integration, analog products can easily seamless docking and other products; different IP products, if there is no supporting management software, customers are often unable to achieve the management of the camera. Therefore, manufacturers need to consider how this product management, system management software for IP manufacturers need to pay attention to the following questions.
The complete product line. Domestic programs generally require the following products: SD / megapixels network camera (typically includes bolt, hemisphere, infrared, high-speed ball, etc.), network video servers, network video decoder, special features camera (such as HD-SDI HD camera) the number of special function camera in a project may be small, but critical to the overall operation of a project often can be controlled throughout the tenders.
Supporting management software. System platform management software for small projects, the need to provide the relevant agreement or in accordance with the docking platform to achieve docking.
Strong technical support. IP product sales is different from analog video surveillance to strong technical team to provide the appropriate technical testing and demonstration work.
R & D team to support major projects. For major projects such as safe city, telecom operators finalists, may according to customer needs, product features custom or system docking, the R & D team docking site or support work.
Effective market strategy to focus the eyes of the beholder, the wise see wisdom, each company has a set for the development of the company IP surveillance vendor should always adhere to the marketing strategy, in close collaboration with channel partners to establish a mutually beneficial relationship, and joint system integrators, distributors, and regional agents of the network video surveillance market is bigger and do a good job, so that together the best network video solutions to market.

With millions of high-definition products in the rapid development of the Internet age, more clearly see millions of HD IP Camera is no longer a concept, but the whole of the inevitable product of the rapid development of video surveillance market, and in the security industry this stage, it's how wonderful interpretation of ourselves, we will wait and see.
Such situation, a lot of R & D staff has been in the search for and development of the "low-cost, high-quality innovative products. In addition to high-definition camera unit price significantly lower, closer to consumers, high-definition monitor can in many ways for the engineering and user cost savings. For example, with the mesh wire coaxial cable to transmit video, audio, power and control signals to save a lot of wire; use of the network for long-distance transmission in a large number of cost savings for our customers, we can say to each other to win. With the development of technology and user demand for high-definition images, HD Network Camera on the road in the security market gets better.
Market Outlook
HD network camera market is in a stage of rapid development, but due to various factors plagued by price, high-definition support, and low light performance, to some extent hindered million development and popularization of high-definition, but as technology continues to enhance the HD IP Camera will become the main force in the video surveillance market in the future.
Megapixel IP camera from all sides, the main application definition with special needs spaces. With the perfection of HD IP Cameras and transmission equipment, cost reduction, HD IP Camera and HD overall solution on the security monitoring applications will be more and more. HD network camera with intelligent analysis will become a new bright spot, will also be more users of all ages.
The author of the survey, Megapixel rate of more than 32% annual increments development, especially this year, millions of high-definition but also usher in the explosive growth and rapid spread. Early million high-definition camera mainly to foreign brands mainly due to the lack of foreign HD IP Camera manufacturers in supporting low-light, resulting in applications with limited sales, coupled with high labor costs, high prices.
Current market conditions
In recent years, video surveillance equipment gradually stepped from the traditional SD Megapixel million high-definition monitor with mature technology and reasonable prices are gradually penetrated the entire video surveillance market, millions of high-definition products have gradually been more and more accepted by users, there have been many cases of successful application, like the Asian Games in Guangzhou, Shanghai World Expo has been adopted by the HD solution, which fully demonstrates the market for high-definition image is recognized, the overall performance of the high-definition camera is accepted .
In everyday life, we often see from the network or TV time and playback in a lot of cases, they are not high-definition, the overall picture is not very clear, especially face details see clearly enough, to monitor The practical effect of playing a big discount. With the attention of the social security monitoring and traffic of the entire city security monitoring camera installed more and more, how to effectively monitor management is currently facing a major problem. Management system networking, remote management requirements are also more and more; many related systems want to be able to call the camera's image resources. These factors explain the limitations of analog cameras, network cameras, especially HD IP Camera market will increasingly demand.
From the definition analog cameras have been close to the limit in a short period of time there is no room for improvement, and millions of HD IP Camera clarity can be said is in a stage of rapid improvement. HD cameras represent the future of surveillance cameras, high-definition monitor in the near future will be the leader of the entire video surveillance industry. Market mainstream HD IP Camera brands are exceptions for Arecont, MOBOTIX, AXIS, IQeye, BOSCH, Sony, and other foreign brands, domestic brands Dahua, Hikvision, Granville as Xindakang, the Yellow River, the world Albert.

HD interpretation of monitoring the mainstream of the times
HD IP Camera is the first theme of today's video surveillance. The one hand, the rapid development of electronic, network technology greatly enhance the value and scope of application; On the other hand, the rapid expansion of the global security needs as well as users increasingly high requirements also greatly stimulated the development of the network camera.
IP camera, network cameras, also known as the name implies, this type of camera can image transmitted through the network to the other end, and distant surfers simply using a web browser to monitor the image. This is a traditional camera and network technology combined with a new generation of cameras.
But not be able to connect to the Internet is a network camera. Network cameras can be divided into two categories, one is the front-end based CCTV analog cameras with video processing and network transmission module is a combination of mixed analog-digital network cameras; pure digital network camera. Both fundamental difference is that the former is essentially still analog camera, its mechanism is A / D-D / A-A / D, after the two analog-to-digital conversion, and ultimately the formation of the network signal, the highest quality can not exceed D1. The realization of the latter mechanism is the analog signal from the A / D signal to the network, thereby greatly improving the conversion efficiency, and thus greatly improve the quality reduction due to the improvement of the quality of the snow noise, so even though the pixels high, but occupy a code flow but little better applicability of its network. Because of the superiority of pure digital network cameras, the analog IP Camera will be phased out in the market.
As people gradually increase the monitoring requirements, in the era of digital surveillance network camera toward the direction of the high-definition, smart development, to become IP Camera trends in the technology sector.
In the era of analog control, the user fuzzy screen covered with snow noise already complain incessantly but can not do anything, because the market was the best camera can only do D1 pixels, in theory, only a maximum of more than 40 million. In the field of non-security, it is overwhelming digital camera, camcorder, PC camera, mobile phone camera, the hundreds of millions or even tens of millions of pixels. Surveillance cameras as a security assistant, analog class surveillance products can not meet user needs, then, "HD" has become the first demand, and, with the high-definition picture quality, low-light, wide dynamic, intelligent such as the higher level of demand can be achieved only with the application.
The high-definition screen is mainly dependent on technological breakthroughs, first proceed to improve the quality of the video source. Digital HD IP Camera relative to the analog cameras, progressive scan, commonly used CMOS sensor built-in AD converter, optical signal into a digital signal output, to avoid repeated AD conversion, damaged small quality and color reproduction, signal anti-interference performance.
Analog front of the camera light sensor output analog signals, followed by transforming into a digital signal, so that the color and luminance processing, digital signal can then be converted into an analog signal output. When you reach the back-end equipment such as DVR, video capture chip (such as: 7130,6805) analog signal into a digital signal, a total of 3 times the AD conversion, the picture is severely damaged when the composite video transmission to the video capture chip , the video capture chip in addition to doing the AD conversion, we need to do bright separation (dressing filtering), because it is difficult to completely separates the luminance and color signals, resulting in traditional analog video surveillance prone color penetration and variegated phenomenon.

seven elements of Selection the network camera
Currently, network camera, network video server as the representative of the third generation of network video surveillance system has made great progress, the rapid increase in the global market share, gradually widely available around the project, the country's "Green City" "Global Eye" project is set off the climax of the network video applications. Network video vendors have sprung up across the country rapidly increasing, the market appeared a large number of network video surveillance products brand, other IT vendors or traditional industries also joined the competition in the online video industry, have launched their own network video products and solutions programs. The face of the market, many network video surveillance products, contractors and end-users how to choose products and to solve the program has been a troublesome issue, analysis of the Selection key elements of IP Camera network video surveillance system, you can give Contractors some suggestions and end-users to choose their own products and solutions.
Now combined with Viagra, as the dot-com Technology Co., Ltd. Shenzhen network video products, focusing on the front-end network camera selection need to pay attention to the analysis of the matters.
Operating system
Network video surveillance system is generally used for long-distance, large-scale monitoring, monitoring equipment needs to run continuously for a long time, which particularly high demands on the stability of the front-end equipment, stable network camera needs a stable operating system, no doubt embedded Linux operating system is an excellent choice. HD IP Camera on the market are mostly embedded operating system, the use of more than Linux2: 6 kernel, Linux is free software and open source, low-cost, high security, portability, has been the first of the operating system as a network video a choice is to determine the pros and cons of a webcam.
Audio and video compression formats
Network camera compression format, the market mainstream image compression format H.264, MPEG-4, M-JPEG, JPEG, MPEG-2, etc., each compression method has its own characteristics, compression formats the different directly determine the image quality and bandwidth consumption, the current mainstream compression format H.264. H.264 image compression techniques to a higher stage, can provide high-quality image transmission in lower bandwidth, the advantage is ideal for large domestic carriers, the access network / backbone network bandwidth is relatively limited conditions . The same quality H.264 coding standard than the previous generation MPEG2 average savings of 64% of the transport stream, rather than MPEG4 ASP average savings of 39% of the transport stream. Many of the world's IPTV service operators will be standard H.264 codec format, including Belgacom, the Netherlands KPN, Thailand ADC Telecommunications, China Telecom and so on. For system integrators and end-users, we need to note that, although currently on the market a lot of vendors claim their own HD IP Camera H.264 compression format, but not necessarily the H.264 standard. Standard H.264 image compression format image by standard streaming media player software to play, you can access the monitoring system of multi-brand. H.264 image stream occupied bandwidth is relatively low, it is conceivable in the 3G network, the transmission of audio and video sync signal.
The external interface of the product
Network camera also need to have a wealth of external interface to provide customers with more value-added features, such as external alarm input and output interfaces; bidirectional audio interface: analog video output interface; supports MiniSD card storage; support POE power supply: RS485 PTZ control interface. Rich interface to meet the special needs of industrial users, system integrators and users an unexpected surprise to meet a lot of features.
Completely open SDK development kit
Network cameras, must be able to provide completely open SDK development kit SDK development kit directly determine the flexibility and stability of the system management platform software. At present, most of the network video market vendors can provide the SDK, but many manufacturers relatively poor compatibility SDK development kit SDK development kit can often only be compatible with the latest version of the product is not compatible with previous versions of hardware products, and even different IP Camera There are different SDK development kit. In just getting started in network video surveillance manufacturers more common for systems integrators, before development, the need for network camera SDK development kit to do an assessment of the current situation also need to know the network camera manufacturers involved in network monitoring life requires an understanding of the technical support capabilities.
Product safety management mechanism
Network video products generally need to be connected in a local area network or even the Internet for remote access, particularly high demands on the network camera security. Security management mechanism of the network cameras on the market just has a multi-level user name and password protection feature that allows authorized users to access and modify the configuration on the IP Camera. Only with this security mechanism is not enough, the general also need to have IP address filtering and HTTPS data encryption algorithm for wireless transmission network camera, with DES/3DES function. Part of the network video market vendors has a complete log management capabilities, the logged-on user IP information, operating records are detailed records of system query. We mentioned here several security management mechanism for the front-end HD IP Camera, and for the entire network video surveillance system, you also need other parts with the implementation of security management mechanism. Such as network transport sector requires a corresponding increase in the firewall hardware and software, the backstage management software industry need to provide the appropriate network security management mechanism, strengthen the safety management transactions for the use of personnel, to prevent the occurrence of safety management password disclosure event. The only way to guarantee the security of the entire network video surveillance system.
Remote upgrade and maintenance
For network video, product upgrades and maintenance is also a very important thing, a good network video products can provide a variety of firmware upgrade approach, such as FTP, HTTP, tool management software bulk upgrade firmware, flexible upgrade can bring a lot of convenience to the customer, according to their preferences for flexible management. How to maintain a very important issue for network video products, after the failure of the product, whether the error system alarm, whether the product is a heartbeat mechanism, take the initiative to send the device to the platform management software is also a very important aspect.
Complete system supporting tools
For a good network video products also need to provide customers with supporting tools management software, such as IP address settings to find the management software, firmware upgrade management software, storage capacity calculations management software, PDA Pocket PC on-site commissioning network camera management software, through a variety of management software to the customer's specific application use. These details can be observed degree of specialization of a company network video surveillance products.

Seven advantages of network cameras
Network camera is a combination of traditional cameras and network technology by a new generation of cameras, network cameras can be an image transmitted through the network to the other side of the planet, and remote surfers without any professional software as a standard Internet browser (such as Microsoft Internet Explorer or Netscape) to monitor its image. Definition of network cameras, there are two popular saying: first, directly connected to the network camera network camera; Second, the use of IP Camera to transmit images.
The typical network cameras include a lens, a filter, an embedded image sensor, an image digitizer, image compressor, and a server with a network connection.
The advantages of network cameras
The main advantages compared to other analog cameras, CCTV or DVR surveillance products, network cameras:
(1) cost savings
Each network camera has its own IP address, data processing capabilities, and built-in application software, can act as a network server, FTP server, FTP client and mail client. Many advanced IP network camera also includes other special features, such as motion detection, alarm signal output / input devices and e-mail support, network cameras not only supports all of the standard analog CCTV camera function, but also provides the user with more system functions and more costs can be reduced.
So far, the the ordinary network image solutions are usually requires a complex system, it comes to the PC, additional software and hardware, workstations, and sometimes video cable systems. Network camera systems often do not require unnecessary equipment and installation input, the system can be directly connected through the network to achieve remote monitoring, eliminating the need for a closed-circuit television, significantly reducing the wire and human costs, reduce the cost.
2 Plug to see
Network camera with a state-of-the-art camera technology and network technology with powerful features. IP Camera with all the components needed to establish a remote monitoring system. Built-in Web server function, only need to access Ethernet, assign an address, you can directly through the network for remote monitoring and remote transmission was observed over the image browser at any time. The built-in system software can achieve true plug-and-play, eliminating the need for complex network configurations.
The image in front of the built-in large capacity memory to store alarm is triggered; built-in I / O ports and communication ports for easy expansion of external peripherals such as: access control systems, infrared sensors, full PTZ. With a software package to facilitate the user to quickly develop application software.
(3) centralized management
Centralized management monitoring system of many analog CCTV system is difficult to control where centralized management refers to the 600-point system like the Brussels International Airport, the use of traditional analog CCTV systems are difficult to control; distance refers to the range of more than 50 km of the system, using traditional analog CCTV systems such as fiber will greatly increase the cost.
(4) long-distance
Network cameras in addition to any corner of the world via the Internet for remote monitoring, network monitoring may also effectively reduce the cost of its "plug and play" function, not the same as analog cameras must be installed coaxial cable, you can use, as long as the use of existing networks are the advantages of the network camera.
5 flexible integration
The system can be easily linked to other security equipment, such as humidity, temperature, smoke, intrusion alarm; moving lights, alarm, locks and other action devices can be connected at the same time, which makes it easy to form a powerful set of security systems. I believe that network cameras in the near future will be in a dominant position on the basis of CCTV.
System performance
System flexible picture settings, according to different applications and user preferences to set the screen size, resolution and monitoring sites, multi-point network control purposes. Such as NCS software support W74GM IP Camera, multi-user can access a network camera with many features, when the alarm is triggered, it can be automatically stored alarm certain period of time before and after the active image.
Easy-to-use network
Based on the global industry standard, network camera can be used with various types of Ethernet devices seamlessly. In a sense, the network camera is a standard network equipment. But network equipment, in a single global network, easy-to-use, inexpensive and so will the characteristics of the network camera.
