  • Full resolution of network monitoring and simulation monitoring comparative advantage


        IP network monitoring has incomparable advantages than the traditional monitoring: Any network will be able to build a network monitoring system. By eliminating the traditional cabling and line maintenance costs, making the network monitoring system installation costs are significantly reduced. Users, IP network monitoring without time restrictions on the location, under the authorization at any time on demand monitoring, plug and play-per-view, very convenient to use. Thus, IP network monitoring is consistent with industry believes that the main trend of video networking surveillance.
        The future, network monitoring will arise in the two trends. First, centralized monitoring alternative to traditional dispersed and isolated monitoring network is the realization of this transformation as a bridge. The second is the intelligent back-office applications. Ago, a large number of video data can not be fully and timely use of a lot of useful information difficult or impossible to extract and save. The benefits of digital network is: With the video analysis technology, multimedia databases, artificial intelligence technology, we can gradually in a timely manner, large amounts of information automatically extracted from the video stream, this information can be transmitted, save and retrieve, you can also to drive the other data, and easily complete the Human difficult task.
        With the gradual development of video surveillance, IP network monitoring is no longer confined to the industrial customers of the enterprise-class applications, the IP network monitoring applications will be gradually towards civilians, the use of video surveillance data to serve the public, such as home security, child care, chain management view.
        One of the advantages of the network camera video surveillance to go beyond the traditional PAL / NTSC video resolution and frame rate limit, to bring high-definition video, high image detail. Megapixels IP cameras, and also provides nearly three times the resolution of analog CCTV cameras, high-end network cameras can provide up to 5 million pixels, or greater resolution.
        However, the only progress in the field of clear images of high resolution is not a network camera, HDTV introduction of video surveillance, the real impetus to HD in the field of video surveillance. With more than megapixels of resolution, HDTV means high definition image detail. In addition, a truly industry-standard HDTV HD IP cameras, to ensure excellent color also attending - at full frame rate and 16:9 image aspect ratio format.
        The introduction of the compression standard MPEG-1 laid the foundation for digital TV, to promote the development of modern TV standards around the world. Motion Picture and Television Engineers, the public - will SMPTE HDTV standards-setting organization, the organization as the authoritative global film, television, video and multimedia standards makers to determine the two most important standards: SMPTE 296M and SMPTE 274M. SMPTE 296M defines the use of 1280 × 720 pixel resolution progressive scan SMPTE 274M defines a 1920 × 1080 pixel resolution interlaced or progressive scan.
        HDTV network cameras means the eye observation of the image people more comfortable, 25/30 at full frame rate video and excellent color consultation - Wide-screen HDTV offers 16 × 9 image is totally cut - the final choice after years of research, it contains more video information. In fact, the real full compliance with the HDTV standard HD IP camera megapixels than normal or HD camera to provide a higher level of image quality, full frame rate video.
        In the field of airports, railways, casinos, city surveillance, passport control, factory production control, the HDTV high-definition network video can provide a more perfect solution.
        Megapixels IP cameras and HDTV IP cameras have many advantages. There are still many applications, the standard resolution IP cameras can also provide the best solution. Usually means that the standard resolution D1 (720 x 576 pixels) resolution, SVGA (800 × 600 pixels) resolution. In complex lighting scenes, extreme sensitivity and wide dynamic range, the standard resolution cameras can play a maximum advantage. Some standard-definition cameras provide higher frame rates per second than the traditional 25/30, suitable for the capture of fast moving objects.
        The key is what you need to see it? Of course, the video surveillance of changes in demand is huge. The most fundamental problem, usually two different kinds of preference:
        Panoramic overview: In this case, its purpose is to obtain a panoramic overview of a scene. For example, the main purpose may be installed in shopping malls, the camera is a flow monitor and view their actions, rather than personal recognition. Or view the parking lot is full or empty space, rather than individual vehicle identification or read license plates. For these applications, you need to have enough resolution to cover the scene.
        High detail: If you need to be able to identify people or objects in the scene. This may be based on the monitoring point, we should clearly see that the customers of each item purchased, or in certain circumstances, need to be able to recognize faces. The high-detail images by installing a IP camera with zoom capability, and closer monitoring. HDTV network cameras will provide more detailed than standard definition network camera, clear detail and higher resolution images.
        Careful analysis of their own video surveillance needs. Typically, the answer lies in a combination of standard-definition network cameras, the HDTV network cameras and megapixels network camera. By balancing the demand, an IP surveillance solution, can have the best cost-effective and meet the availability of the desired image.
