Correct understanding of HD IP Camera

Correct understanding of HD IP Camera
Millions of high-definition network monitoring system will be further expanded, more high-definition network monitoring products have sprung up, most people are not yet out from analog surveillance market scam, HD storm struck. The face of many brands of HD IP Camera, we go from here? Below, I will take you to a simple discussion.
    
1, a correct understanding of the concept of "HD"
     HD IP Camera, referring to the monitoring system based on digital technology, network transmission mode camera, monitor and video resolution of at least 1280 * 720 (that is, we often say 720P) above, below this are false HD or does not belong to high-definition. Traditional analog surveillance system to monitor and video resolution due to technical limitations, the maximum can only reach D1 (704 * 576) resolution effect, therefore, whether analog cameras is the number of lines, are excluded from the HD category.
    
What resolution HD camcorder is the best?
     Currently, the resolution of HD IP Camera ranging from 100-1000 megapixel, from the point of view of the video surveillance applications, the resolution is too low or too high will directly affect the normal use of the system, construction costs, bandwidth and storage and other aspects of pressure. Therefore, the composite price, clarity and other factors, the 2 million pixel CMOS chip HD IP Camera will have a higher price, to better meet the actual needs of customers. But the same 2.0 megapixel IP Camera, the frame rate and resolution will vary, generally 15, 25 and 1920 * 1080 and 1600 * 1200 two currently on the market is 25 1920 * 1080 such majority.
    
3, see the hardware and software features of the camera.
     In general, a high-performance, cost-effective HD IP Camera, the face of the diverse needs of market users, hardware, need to have basic voice monitoring, voice intercom, alarm input and output, 485 control common functions and application module can access the POE, WIFI, 3G, etc., to meet the demand for a variety of application environments. The software has a user-friendly settings, management, operation platform, easy to use, at the same time, the various functions of the software to meet the application requirements of the general large-scale monitoring system.
    
4, the actual application effect and Configuration
    HD network camera manufacturers in order to facilitate the customers to understand the performance of their products, usually to provide services online demo or video file to download, customers can play the video to watch the actual application, a preliminary understanding, then the HD network camera itself is the most important several accessories such as light-sensitive chip, infrared light, lens, filter switching devices for consultation, and can be in-depth understanding of the performance of the product. General quality of HD IP Camera will use a higher pixel sensor chip manufacturing, infrared light products in Taiwan, the lens 200 million or 300 million pixels high-end lens, and is equipped with IR cut filter, thereby improving network monitoring the performance of the IP Camera.
    
5 compatibility
     Previously, the majority of HD IP Camera manufacturers are fighting each other, and did not form a uniform standard, the front-end and back-end products down to the different vendors can not be compatible with, to a large extent, prevent the pace of high-definition network monitoring system to promote the application of . The current major manufacturers and users have realized that the lack of this problem, various manufacturers in the industry is also actively involved in and stepping up the development of high-definition network surveillance system interface standards, and through secondary development to meet the user more product compatible. Currently, the most widely used high-definition network surveillance system is ONVIF-compatible protocol, and is expected to become the domestic network cameras unified management platform standard. HD network camera, vendors should be able to support the latest version of the ONVIF protocol, which is compatible with more use of the product and unified management to achieve interoperability, data sharing.
    
6, the back-end solutions and products and services
     A complete set of high-definition network monitoring system includes a front-end video equipment, network transmission, back-end storage, display control, decoding on the wall, a large platform management applications, the availability of the overall application solutions is a measure of a HD network monitoring products supply commercially important criteria. Require suppliers have the appropriate technical strength and has an overall capacity of the solution, in order to ensure to provide customers with professional, fast service. Therefore, the supplier's product lines and after-sales service system can also be used as an important basis for customers to choose products.
    
Conclusion:
    
Through the above points, I believe we will be able to choose to meet their own needs of HD IP Cameras and supplier jointly launched the development and application of high-definition network surveillance products!
