How to build a blameless ip video surveillance system

There is no doubt that the success of the basic elements of ip video surveillance is network,it is necessary for the requirements of the network environment, to maintain a good network can meet the performance parameters of user in maintaining definition video.The uncompressed real-time video signal of a megapixel ip camera may take up to 21Mbps broadband per second, even a real-time signal need 1.5Mbps bandwidth when using the latest compression algorithm,Meanwhile, the motion detection function may also affect the bit rate and bandwidth usage. Meanwhile, the motion detection function may also affect the bit rate and bandwidth usage. In any case in order to ensure that the video quality, the resolution of the network camera must be required not less than 4CIF, the network must be able to meet the resulting bandwidth requirements.Comprehensive verification of existing network architecture will help to determine which lines need to be upgraded, because most of the fixed network camera support POE power supply, install these cameras only need a Cat-5e cable, this will reduce the cost of installation. Depth study of the network topology can also check out any need to modify the configuration and performance monitoring system more flexible, these preparation will ensure that the system implementation success rate and reduce the subsequent application problems.
If the network infrastructure is aging, and sometimes can not guarantee that the digital video resolution, size and transmission speed even if the network bandwidth of 100Mbps, almost half the bandwidth consumed by the system, only around 54Mbps for transmission of video, data and voice. Generally require special network for scalable and easy to manage, such as high-bandwidth applications like ip video surveillance, which includes recording and playback settings in different paths, as well as the use of a dedicated storage area network or IP subnet. Develop a dedicated ip video surveillance system will be related to other network devices, such as network switches, servers, virtual matrix, encoder, etc., these device drivers network video Unlike traditional switches, network switches can ensure that the bandwidth of the network, which of the network camera video recording and monitoring has the appropriate bandwidth protection; cost-effective it will expand once the network is established, each of the components in the system can be stand-alone installation, operation and regulation, and also can be a multi-point monitoring, and not just limited to coaxial cable of a single point-to-point equipment; you can change the order to match with the system, the level of compression; due to the private network using standard TCP / IP, user name and password to enter the system, so any networked computer can be used as observation and operation the centers use standardized database and protocol can also interact with other security components and access control.
Integrators should research and test network camera products from different vendors in the IP system is highly integrated trend before mounting system.Standardization of key technologies that can help to create a simpler, more powerful system, and thus easier to maintain, upgrade, expansion and management. This standard will be the user requirements, general industry standards or integrators management of internal drive. The efforts made by the industry has begun to emerge, such as ONVIF and PSIA standards of performance in the near future, more ip video surveillance system will likely use the HD standard, the current products can plug and play. The user wants to open standards for various technologies can be integrated into the same system, the vendor is working through the APIs, SDKs and strategic partners to meet their expectations, to ensure that products from different vendors easier integration. So the user will not be confined to a single supplier. As the network continues to lead the ip video surveillance, multi-system demand for higher integration will continue to grow, such as access control, POS systems integration. System integrators, technical expertise can help build a new system or to improve the existing system, allowing the system to maximize interoperability and reduce TCO.
The size of the project is a need to consider carefully the factors, and it often determines a video system is the need to build a private network or shared building / internal network. No matter what the size of the network infrastructure must match the needs of the system, system integrators can help make up for the lack of customers internal staff, the most common physical security and IT teams, by identifying the key issues to design a solution to meet the needs of both . IT / security interface type is often determined by the size of the project, the construction of large-scale projects usually contain many stakeholders, this situation becomes more complicated. For example, whether the establishment of an independent private network for ip video surveillance systems and security base system, or whether the two systems separate separate design and operation. Any product on the network must be properly connected and management, and this is the fundamental responsibility of system integrators. Provide information and data safety monitoring, network transmission, accumulation and storage of these data, system integrators, co-operation can guarantee the best solution. Security and IT managers to work, system integrators can design, provide support sustainable security system matches a customer strategy. Compared with simulation technology, IP system with high scalability, integration, it requires more technical knowledge to provide customers with a better system function. Because of its flexibility, the system can be early noted that the change of system design and installation, to ensure that the various elements of the IP system can be in any place to maximize network technology.
