\nWith the rapid development of the intelligent industry in recent years, the rapid application of security monitoring systems in banks, transportation, community, public security, and even home, people have become more and more aware of the importance of security cameras, but in the face of various types And security cameras with different technical features, how do we choose the suitable security camera from the aspects of shape, lens, resolution, storage mode, connection mode, power supply mode, video coding and so on.<\/p>\n

  • Shape<\/span><\/li>\n<\/ul>\n

    \nThere are many types of CCTV camera, usually in the shape of a security bullet camera, dome cctv camera, PTZ Camera and <\/span>panoramic dome camera<\/span> etc., and also in the shape of a robot camera, plug camera, bulb camera and so on.<\/span><\/p>\n

    • Lens and Zoom<\/span><\/li>\n<\/ul>\n
      \n
      \n<\/span>The lens of Cctv camera , generally has fixed lens 2.8mm\/4mm\/6mm\/8mm\/12mm and varifocal lens and motorized lens camera<\/span>. Each product line can choose the lens focal length to meet the shooting needs of indoor and outdoor environments. such as 4x zoom, 10x zoom, 20x zoom and 30x optional zoom.<\/span><\/p>\n

      In general, the shorter the focal length, the larger the range of angles seen, but the shorter the monitoring distance.For example, the 2.8mm focal length is suitable for narrow environments such as elevators and corridors, and more spacious places such as parking lots, factory workshops, and courtyards should use 6mm lens or more.<\/p>\n

        <\/span><\/p>\n


        \n<\/span>Buy a surveillance camera, Should we choose the suitable resolution for the camera?<\/span><\/span><\/p>\n

        We know that the larger the resolution of the camera and the higher the pixel, the clearer the image will be. Ordinary home indoor surveillance cameras choose 1MP, 1,3MP and 2MP Full HD camera, resolution 720P, 960P or 1080P surveillance cameras<\/span>, which can basically meet our monitoring needs.<\/span><\/p>\n

        If you are using outdoor or large security projects, such as streets, train stations, plazas, stadiums and other outdoor large-scale scene monitoring, we recommend using 4mp, 5mp or 8mp 4K ultra hd camer<\/span><\/span>a<\/span>. However, the higher pixel of the camera , the larger the memory space is occupied, and under the same conditions, the storage time becomes shorter. Therefore, when considering the definition, we also have to consider the problem of storage time.<\/span><\/p>\n

          \n
        • Storage Method<\/span><\/li>\n<\/ul>\n

          \nWhen installing a camera, people are generally worried about the problem of video storage. After all, the stored video is gone, and it loses the role of the camera to restore the truth. There are three ways to monitor storage, one is network hard disk storage, 1. local storage, 2. SD card storage, 3. cloud storage.<\/span><\/span><\/p>\n

          Network hard disk storage<\/span>: It is suitable for indoor indoor outdoor network monitoring equipment, which requires long-term video recording. Such as IP Camera,  HD NVR, WIFI NVR Kits, POE CCTV Kits<\/span>.<\/span><\/span><\/p>\n

          Local storage<\/span>: Power-on plug-in, such as TD memory card, will automatically record, without any settings and support for network disconnection. However, this is an automatic loop recording, which automatically overwrites the early recording after the TF is stored. Suitable for indoor or outdoor smart cameras such as WiFi PTZ Camera, WIFI Solar Camera<\/span><\/span><\/p>\n

          Cloud storage<\/span>: Don’t worry about surveillance cameras, hard disks or TF cards are damaged, you can access cloud video data at any time. With the development of the Internet, cloud storage is undoubtedly the mainstream direction of future storage methods. At present, many WiFi smart cameras support cloud storage in addition to local storage.<\/span><\/p>\n

            \n
          • Connection Method<\/span><\/li>\n<\/ul>\n

            \nWith the development of the times technology, from analog cameras to IP network cameras, the networking method is constantly changing, and IP network monitoring should be the development direction of future network monitoring.<\/span><\/p>\n

            Nowadays, many security cameras are network surveillance. The network connection methods of these cameras are also divided into three types: 1 network cable connection; 2 wireless connection; 3AP hotspot connection;<\/span> all three methods have their own advantages and disadvantages, which can be selected according to actual conditions, such as with a network cable connection, the network is stable, but the wiring may be inconvenient; <\/span>wireless transmission, installation is convenient, but the wifi network is prone to instability; AP hotspots need to be used in the LAN, there are distance restrictions. However, considering the user’s needs and experience, many CCTV cameras on the market support more than two types of network connections.<\/span><\/p>\n

              \nSecurity monitoring equipment power supply can be divided into three types: independent power supply, centralized power supply or POE power supply<\/span>, but this is for large engineering, each power supply has its advantages and disadvantages.<\/span><\/p>\n

              For example, independent power supply maintenance is easy, anti-interference is good, but construction is troublesome. Centralized power supply maintenance is simple, low energy consumption, but the anti-interference is poor, and the monitoring system is prone to paralysis. POE power supply, No need external power, but mainly in the network cable and distance limit, the equipment cost is high.<\/span><\/p>\n

              • Video Coding<\/span><\/li>\n<\/ul>\n

                \nWhat is video coding?<\/span><\/p>\n

                The video encoding method refers to a method of converting a video format file into another video format file by using a specific compression technique. The main role is to compress and process redundant data, compress file size, reduce bandwidth, and reduce storage space.<\/span><\/p>\n

                With the rapid development of technologies such as ultra-high definition technology and cloud storage, new requirements and new challenges are put forward for the transmission and storage of massive video data. Compared to traditional H.264, , and even + video coding methods<\/span> are beginning to appear and are beginning to be used in security surveillance, such as face recognition camera<\/span>. The video compression efficiency is improved, and the bandwidth and storage cost are greatly reduced, which has a positive effect on the popularization of high-definition network video surveillance.<\/span><\/span><\/div>\n<\/div>\n<\/div>\n
