Essential knowledge of select Network Video Surveillance Equipment

Essential knowledge of select Network Video Surveillance Equipment

Essential knowledge of election

From the technical analysis, network video monitoring system is involved in computer technology, traditional CCTV, network technology, anti-theft alarm technology, and other weaknesses in systems integration, is a cross-integrated multi-disciplinary systems engineering. Designed for network video surveillance system, we can front-end monitoring equipment , network transmission resources, the system platform software features, network planning, descriptive analysis of storage mechanism.

1, the operating system

Network video surveillance systems are generally used for long-distance, large-scale monitoring, continuous monitoring equipment takes a long time to run, which the proposed front-end equipment, particularly high stability requirements, stable network cameras need a stable operating system, no doubt embedded linux operating system is an excellent choice. Network camera on the market today are mostly embedded operating system, using more than Linux2.6 kernel, because Linux is free software and open source, low cost, safe, portable and strong, has served as the first online video operating system choice, is currently the judge the merits of one aspect of the network camera.

2, audio and video compression formats

The current network has a variety of compression format camera on the market mainstream image compression format H.264, MPEG-4, M-JPEG, JPEG, MPEG-2, etc., each have their own characteristics compression, the compression format directly determine the difference in image quality and bandwidth consumption, the current mainstream compression format H.264. H.264 compression technology to rise to a higher stage, able to provide high quality low bandwidth video transmission, the advantages are for users to large domestic operators, access / backbone network bandwidth, the situation is relatively limited. Under the same picture quality, H.264 coding standard than the previous generation average savings of 64% of the MPEG2 transport stream, while the average savings of more than MPEG4 ASP to 39% of the transport streams.IPTV service provider in many of the world will be H.264 as the codec standard format, including Belgium Telecom, the Netherlands KPN, Thailand, ADC Telecom, China Telecom and so on. For system integrators and end users, we need to note that, although so many vendors on the market today claim to be H.264 network camera is the compression format, but not necessarily the standard H.264, H.264 non-standard network camera, the user must select the standard H.264 compression format, image compression standard H.264 standard format images can play streaming media player software, you can access multi-brand monitoring system.

3, the product-rich external interface, and improve product features

Rich network camera also requires external interface, to provide more value-added features, such as providing external alarm input and output interfaces; two-way audio interface; analog video output interface; supports MiniSD card memory; support POE power supply; RS485 PTZ control interface . Rich user interface to meet the special needs of the industry, giving system integrators and users is an unexpected surprise to meet specific functions.

4, completely open SDK development kit that provides a complete solution

Network cameras must be able to provide full and open SDK development kit, SDK development kit directly determines the system management platform software flexibility and stability. Network video market, many vendors can provide most of SDK development package, but many companies are relatively poor compatibility with SDK development kit, SDK development kits are often only compatible with the latest version of the product, not compatible with previous versions of hardware products, Shenzhen different network cameras There are different SDK development package. The current situation just to get involved in a number of relatively common network video surveillance company, so for the system integrators in the development is required before the network camera SDK development kit to do an assessment, in addition to the camera makers need to understand the network involved in network monitoring period the need for technical support capabilities. Jing Yang can not only provide users with complete SDK development package, the network video products being integrated into other platforms; while Jing Yang for a wide range of industries provide a complete network video solution, and can be special for special occasions solution. Jing Yang network video solutions are cost-effective, flexible, scalable, future-proof and other characteristics, and other such easily with access control and building management systems integration.

5, product safety management system

Network video devices generally are connected to the LAN or Internet for remote access, so the network camera the safety of the special high demand, the market network camera security management system is a multi-level user name and password protection, allowing authorized users to access and modify the network camera configuration. Only with such security protection mechanism is not enough, the general also need to have IP address filtering, HTTPS data encryption algorithm, to support the wireless transfer of network cameras, also need to have DES/3DES functions. Part of the network video market, manufacturers have improved log management, log the user's IP information, and operating records and detailed records so as to prepare the system queries. Several mentioned here mainly for front-end security management of network cameras, and video surveillance system for the entire network, but also with other parts of the implementation of safety management. For example, departments need to increase network transmission corresponding fire wall software and hardware, background management software industry needs to provide appropriate mechanisms for network security management, increased use of safety management personnel transactions, prevent password leakage and other safety incidents. The only way to ensure that the entire network video Surveillance Equipmentsecurity.

6, remote upgrade and maintenance products

For network video, the product upgrade and maintenance is also a very important thing, a good network video products can provide a variety of firmware upgrade options such as FTP, HTTP, tool management software, firmware upgrades and other bulk methods, flexible upgrade , can bring a lot of convenience to customers, according to their own preferences for flexible management. For network video products, how to maintain after the product failure is also a very important issue, whether the system error alarm products, the product is a heartbeat mechanism to take the initiative to send the device information to the platform management software is also a very important aspect, you are worried about You, Shenzhen Jing Yang Digital Technology Co., Ltd. are taken into account for you, you can rest assured that worry-free use.

7, a sound system supporting software tools

For a good network video products, also need to provide supporting tools to manage a small software, such as IP address settings easy to find management software, firmware upgrade management software, storage capacity management software, computing, PDA Pocket PC Camera site commissioning management software, management software to customers through a variety of special application to use convenience. Through these details, we can observe a corporate network video surveillance products for the professional degree, from a test to see a company's service level, I think you're the first choice if such a product, choose such a management system, basically You may not have to worry about.
