Network surveillance cameras do not sell products sell services
IP video surveillance market has been developing steadily since 2009 , until 2011 network monitoring set off a boom in the domestic security market , today , even billion market opportunity in front of us , IP HD monitors praised still face the embarrassing situation . Megapixels HD has become a buzzword in the security industry , lack of standards and the second and third tier markets hiatus become the biggest obstacle restricting its development .
Advantages and disadvantages of IP surveillance , but how to make the network video surveillance market is more mature, still seems to be a topic worth exploring .
HD network camera monitoring the fate of small innovative change
Analog monitoring technology as the representative of the video surveillance has improved the development history , IPnetwork camera surveillance is an emerging field , completely contrary to analog surveillance technology. There are many large contractors said , IP surveillance can indeed bring greater benefits for them , but if you want to expand the market, how to achieve low cost, high reliability it? Time will be able to solve the problem, but I am afraid there can solve the urgent needs to be seen.
User requirements determine market trends, end-user point of view of network video product features but will IT technology , software, etc. through the Internet integration. Even this little " innovation" is indeed capable of causing widespread concern of users , network IP Camera as the representative of the product with better flexibility and scalability , dramatically reducing installation costs. Despite the need for more complex network setup and monitoring software , but the long-range surveillance undoubtedly solve many problems.
Trends in wireless network monitoring platform
To meet the needs of users , network video surveillance to be large-scale promotion . Promoting safe city construction projects , the first-tier cities is almost complete analog to upgrade high-definition monitor , the user can truly appreciate the advantages of IP surveillance which it ?
Network camera is no longer simply the product features, it is a manifestation of services. Therefore, how to provide effective services will be an important factor in security companies to gain market share , product resolution and prices have not been listed as a key factor . To allow users to better understand the products, services should include not only maintain , but service. Respond quickly to changes in market demand, and constantly optimize the product , with standardized interfaces and protocols.

Network camera and analog cameras What is the difference ?
Network camera and analog cameras What is the difference ?
Analog cameras and IP camera are today's mainstream products are used in various industries , so we use them in what they know about what is the difference between the two is it ?
Network camera ( digital camera ) is simply directly to the camera itself and the internal circuit by the CCD image captured into the digital signal via a network cable , the switch directly transmitted to remote monitoring easily . Simple analog camera image is converted into an analog signal , is transmitted through a coaxial cable, generally used for closed-circuit monitor . The difference between analog cameras and Network camera as follows:
1 , clarity
Network Camera : Progressive scan (up to millions or even tens of millions of pixels ) , more suitable for capturing moving targets , even moving at high speed can also provide a clear picture of the image .
Analog cameras : interlaced ( resolution 4CIF, can only reach 400,000 pixels ) , catch them at high speed moving objects , can cause image blur.
2 , monitoring
Network Camera : Built-in WEB, using a standard WEB browser on your PC , you can manage and view images. The ability to remotely manage and view images. Presence on the network camera can be remote image data hard drive, easy to find , easy to store, will not be destroyed.
Analog cameras : closed , only watch inside , not remote monitoring . Video data can only be stored locally , not remotely view , easily destroyed criminals .

What are the advantages of video surveillance network camera ( 2 )
What are the advantages of video surveillance network camera ( 2 )
Five reasons : Integrated PTZ control and input / output ports
For analog cameras is concerned, if you need to realize PTZ ( pan and zoom ) control , in addition to video cabling , but also need to provide specialized control signal line , it will increase the cost and inconvenience to the construction . network camera can transmit video signals through the same network , and PTZ control commands , which can greatly reduce installation costs and to achieve higher user flexibility . In addition , network camera can also be integrated alarm input and output ports , to achieve joint control of other security systems alarms , door locks and the like. These features in addition to further cost savings for users , but also further increase the network camera features and integration with other systems potential.
Six reasons : Integrated Audio
In some applications, the audio information is becoming increasingly important. For analog systems , if you need to get audio support, only through additional audio wiring work can be achieved. The network camera can capture the audio through the built- in microphone at the front end or other external device, and the audio information synchronized with the video information , audio information, or be integrated directly into the video stream which , finally transmitted to the rear end of the network or to monitor recording device . In fact, the only network camera can make audio support functions become easy to install and cost-effective , it can support full-duplex audio , so that the user can use the phone as easy to use audio features . In the example in Figure 7, the network camera allows users and visitors for two-way audio communication, and remote control door opening and closing .
Seven reasons : safety communications
Analog cameras use coaxial cable to transmit video information , which does not have any encryption and authentication mechanisms. In this case , as long as they know the location of the video cable , anyone can watch one video screen by means of the transmission line ride . Worse, since the bad guys can be a deceitful , video surveillance will be a critical signal to switch to other sources , so that the user's video surveillance system complete failure ( as the movie scene often appear like ) . But in terms of the network video system , network camera can capture the video signal is first encrypted and then transmitted through the network , which can ensure that the video information can not be accessed or tampered with by unauthorized personnel . System through the use of high security digital certificate authentication for connection requests , to ensure that only specific network camera to be able to access the system , thus effectively avoiding fraud. network camera can also join the "Watermark " message in the video data , the " Watermark" summary information can include images , time, place, date, user information, alarm information, etc., so that after security incidents to ensure an effective system to save evidence. These functions in a simulated camera is simply impossible to achieve.
Eight reasons : flexible, economical and practical infrastructure based
The analog video signal is normally transmitted through expensive coaxial cable , fiber optic or wireless private , no matter what the transmission technology, the image quality will receive the impact transmission distance. In long distance transmission when the analog video signal , various intermediate devices must fit precisely and to ensure that the range of adjustment of the image quality degradation can be received in a situated . In addition, the power supply for the camera wiring , add alarm input and output , and audio cabling installation projects will further complicate deployment . The IP-based digital systems are able to overcome the relatively low cost of these difficulties , and to provide users with more options.
Like at any one location in the world via the Internet can view pictures on the website , you can at any corner of the world through the Internet network camera provide viewing digital pictures that span continents and oceans will never long-distance transmission quality degradation caused by the phenomenon . The difference is that with analog video , IP network technology is a global standard of mature technology, IP-based video stream can be compatible with each other through a variety of transport infrastructure on a global scale . As a result of the type of packet -based communications , many different types of data stream can be transmitted over the same data line. In some new projects which often uses low-cost Category 5 cable , gigabit Ethernet , and a data cable can transmit hundreds of full frame rate video streams .
Nine grounds : the real digital solutions
In an analog video camera , an analog signal generated by the first CCD sensor are converted A / D ( analog / digital ) converter to digital signals, so that the video image and sound can be processed through its built-in DSP chip. After the digital image signal is then processed by the DSP and converted back to an analog signal for transmission on coaxial cable. Finally, when the analog signal reaches the rear end of the
DVR , the DVR has been re- digitized and stored on the hard disk. As can be seen , in this process , transforming the image signal to be subjected to three , and each time the conversion will cause different degrees of decline of image quality . In the network camera , the image After digitization digitization will remain a state without the need for multi- frequency / analog or analog / digital conversion , thus avoiding the image degradation phenomenon.
Ten reasons : lower total cost of ownership
When it comes to these network camera have a range of advanced features , some would say that these advanced features will inevitably result in increased equipment costs. Indeed , if only to get the price of the camera itself to do a comparison, network camera certainly seems to be rather expensive. However, if the object is to compare the cost of each video signal , then the flexibility of high -performance network camera
Obviously you can and DVR -based analog systems equal. As the network video system applications and back-end storage capabilities that the industry can use generic, open standards-based server hardware , rather than as an analog system that must use a dedicated hardware platform ( such as DVR), so in many system configurations, based on the front-end equipment cost network camera video surveillance system is very
To appear lower . This is for a number of large systems is especially important because the storage and server hardware typically account for a large part of the total cost , while the use of IP camera can greatly reduce the cost of device management and acquisition area. Cost savings come from the infrastructure network camera are used . In addition to carrying video surveillance business outside , Internet, LAN and wireless
Various networks , such as IP-based network can also carry other types of applications within the enterprise , compared with the traditional coaxial cable and optical fiber, the construction cost of these networks is very low .
Conclusion: The future belongs to the network camera
JPFreeman leading industry analyst predicted that in the field of video surveillance , network camera market will be the fastest growing market , sales network camera will surpass analog camera in 2008 . Because IP -based network security management (SecurityManagement) greatly expanded the understanding of people for security management and implementation tools, and therefore is considered to be the development direction of the next generation of advanced security management. On the other hand , some analog cameras due to the defects in flexibility and performance , and therefore can not meet the requirements of next-generation security management , network camerais bound to be replaced . As the network camera will capture images as well as the ability to frame intelligent image processing stripped from similar back-end equipment such as DVR , so the size of the video surveillance system can no longer restrict the ability of the back-end computing equipment , systems obtain greatly improved extensibility . End- user network video surveillance system can choose to use cost-effective general-purpose servers and storage for video , but you can also choose the product most suited to their needs from a large number of video management and analysis software.
In summary, the network camera enables users to their applications can be transferred from the special equipment (DVR) to open systems which , in addition also allows users to take full advantage of the network, the advantages of digital and intelligent , all this will constitute a powerful promotion of force, so that more and more users choose thenetwork camera.

The difference is that with analog video , IP network technology is a global standard of mature technology, IP-based video stream can be compatible with each other through a variety of transport infrastructure on a global scale . As a result of the type of packet -based communications , many different types of data stream can be transmitted over the same data line. In some new projects which often uses low-cost Category 5 cable , gigabit Ethernet , and a data cable can transmit hundreds of full frame rate video streams .
Nine grounds : the real digital solutions
In an analog video camera , an analog signal generated by the first CCD sensor are converted A / D ( analog / digital ) converter to digital signals, so that the video image and sound can be processed through its built-in DSP chip. After the digital image signal is then processed by the DSP and converted back to an analog signal for transmission on coaxial cable. Finally, when the analog signal reaches the rear end of the
DVR , the DVR has been re- digitized and stored on the hard disk. As can be seen , in this process , transforming the image signal to be subjected to three , and each time the conversion will cause different degrees of decline of image quality . In the network camera , the image After digitization digitization will remain a state without the need for multi- frequency / analog or analog / digital conversion , thus avoiding the image degradation phenomenon.
Ten reasons : lower total cost of ownership
When it comes to these network camera have a range of advanced features , some would say that these advanced features will inevitably result in increased equipment costs. Indeed , if only to get the price of the camera itself to do a comparison, network camera certainly seems to be rather expensive. However, if the object is to compare the cost of each video signal , then the flexibility of high -performance network camera
Obviously you can and DVR -based analog systems equal. As the network video system applications and back-end storage capabilities that the industry can use generic, open standards-based server hardware , rather than as an analog system that must use a dedicated hardware platform ( such as DVR), so in many system configurations, based on the front-end equipment cost network camera video surveillance system is very
To appear lower . This is for a number of large systems is especially important because the storage and server hardware typically account for a large part of the total cost , while the use of IP camera can greatly reduce the cost of device management and acquisition area. Cost savings come from the infrastructure network camera are used . In addition to carrying video surveillance business outside , Internet, LAN and wireless
Various networks , such as IP-based network can also carry other types of applications within the enterprise , compared with the traditional coaxial cable and optical fiber, the construction cost of these networks is very low .
Conclusion: The future belongs to the network camera
JPFreeman leading industry analyst predicted that in the field of video surveillance , network camera market will be the fastest growing market , sales network camera will surpass analog camera in 2008 . Because IP -based network security management (SecurityManagement) greatly expanded the understanding of people for security management and implementation tools, and therefore is considered to be the development direction of the next generation of advanced security management. On the other hand , some analog cameras due to the defects in flexibility and performance , and therefore can not meet the requirements of next-generation security management , network camerais bound to be replaced . As the network camera will capture images as well as the ability to frame intelligent image processing stripped from similar back-end equipment such as DVR , so the size of the video surveillance system can no longer restrict the ability of the back-end computing equipment , systems obtain greatly improved extensibility . End- user network video surveillance system can choose to use cost-effective general-purpose servers and storage for video , but you can also choose the product most suited to their needs from a large number of video management and analysis software.
In summary, the network camera enables users to their applications can be transferred from the special equipment (DVR) to open systems which , in addition also allows users to take full advantage of the network, the advantages of digital and intelligent , all this will constitute a powerful promotion of force, so that more and more users choose thenetwork camera.

What are the advantages of video surveillance network camera (1 )
What are the advantages of video surveillance network camera (1 )
Generally speaking, to a lot of factors involved in the security industry to converged IP networks process , to be discussed below is not limited to network camera and analog cameras are different in all aspects . Such as system performance , openness , interoperability , flexibility, sustainability and network connectivity, and other factors are to be considered important content. However, this article will discuss mainly for the 10 most important difference between the current IP camera and analog cameras existed , and further analyze why these differences is a key factor when purchasing the next camera must be considered .
One reason: the end of interlaced scanning problems
Analog cameras at high resolution (4CIF) condition will encounter a very prominent issue that interlace problems. This is because some of the analog video image is composed of scanning signal lines , each of a complete image field signal is again composed of two interlaced , even if the DVR is connected to the analog signal is true . This means that we see each image acquisition time is composed of two different " demi " picture merger .
Figure 3 is the actual effect of the progressive scanning and interlaced contrast to auto screen 20km / h speed of travel . As can be seen from the figure , either progressive or interlaced , the still picture object ( such as a brick wall ) can be clearly presented. However, for a moving object ( such as cars and driver ) , the interlaced picture significantly blurred. As can be seen from the enlarged picture detail , from the use of progressive scan picture you can clearly identify the driver's facial contours , while interlaced scanning is impossible to see. If the driver of a car theft thief , then obviously interlaced picture useless to hunt for a job .
Two reasons: to support PoE technology to effectively reduce costs and improve system reliability
PoE (PoweroverEthernet), means to provide power to the device through the Ethernet network technology , the standards required by the IEEE802.3 af , IT is a mature industry standard . PoE technology allows network devices can receive data and power simultaneously work over a single Ethernet Category 5 cable , facts prove that the technology can save a lot of installation costs for the user. This means that users do not have to support PoE cameras specifically for power installation work , while analog video surveillance systems for analog camera power has always been a major engineering difficulties , but also one of the major costs. In addition , support for PoE enabled network camera also can be used in conjunction with UPS uninterruptible power supply system , to achieve centralized management of power , thus greatly improving the reliability of the system , the network camera can still work in case of power failure . As can be seen from Figure 4 , regardless of whether support PoE , PoE network camera can benefit from the technology .
Three reasons: one million pixel resolution
Due to constraints NTSC / PAL standard , the highest resolution analog camera has been limited to 4CIF, roughly equivalent to 40 million pixels look. In recent years , high-resolution computer monitors and digital IP Camera continue to emerge , end users have begun to require millions of pixels of image resolution up to the level of end-user video surveillance applications also began to make a similar request . Webcams
Like the highest resolution machines can reach millions of pixels or higher , and therefore can provide more picture detail and cover a larger area ( Figure 5 ) . High resolution to ensure safety in the accident, you can clearly distinguish facial features perpetrators or their handling of goods from the video screen or monitor the video, so that users will not be wasted for the security system investments. In addition , high-resolution camera feature allows the network can also provide some, such as digital PTZ (Pan / Tilt / Zoom) and other special features .
Four reasons : the intelligent integration to the front
In the current video surveillance system, there are too many video data is recorded and stored, but these data are mostly unimportant pictures , information important events tend to be submerged in a flood of video data which , giving the event analysis and processing of a great deal of difficulty , but also a waste of valuable storage resources. Latest appear intelligent video technology to solve this common problem may be provided, and has become the next big trend in online video development. High-end IP Camera can fully meet the needs of intelligent video applications , they can be built into mobile video detection (VMD) and event management functions , so the camera itself can decide when to send video , at what frame rate and resolution to send, and when should alert the security personnel which prompts them to pay attention to the monitor screen or take appropriate action. Even some advanced intelligent video analysis algorithms ( such as license plate number recognition , people counting , etc. ) can also be integrated into the network camera were .
By using network camera, intelligent systems can be integrated into the front end of which the video surveillance equipment , enabling users to get a more efficient and powerful than traditional DVR or other centralized system of video surveillance solutions . Intelligent network camera also solved another dilemma in the field of video surveillance is emerging : the limitations on the computing power of a centralized video surveillance system can not be achieved on a large number of real-time video analysis . The network camera has a dedicated , highly integrated hardware, its own advanced video analysis algorithms can be realized , this feature greatly reduces the performance requirements for the back-end device , so that users can build a massive surplus of intelligent video systems .
