HD IP Camera advantages and challenges facing the
After years of market-driven, it is for the advantage of IP Camera, has already heard, the network camera has the main advantages include the following:
The signal processing is more efficient: pre-coding, the original image to distance coding compression greatly shortened effectively reduce signal loss;
Used directly or indirectly with progressive scan technology: effectively enhance the ability to restore the dynamic image to reduce image distortion;
Network power supply (PoE): a single network cable to transfer data, but also for power supply, convenient wiring, can effectively reduce maintenance costs in the long term;
Supports two-way audio: provides high compression ratio audio & video streaming, integrated audio capture and speaker products to meet a variety of audio mining, voice intercom demand;
Integrated convenience of a variety of functions: intelligent analysis, alarm linkage, WIFI, 3G, ISP technology, technology integration provides a more open platform;
Information Security: IP Camera available data encryption, watermarking technology and authentication technology video information security management, video detection, alarm linkage mechanism to prevent network outages, vandalism and other fault occurs;
Standardization: network camera easy integration PSIA, ONVIF standard protocol effectively promote video surveillance in international standardization process;
High definition: HD IP Camera monitor, from 100 million pixels to 500 million pixels, even the future of 800 million pixels, 10 million pixels promotion details for each industry monitoring to provide technical support to provide basic support for high-definition monitor.
Have the advantage, but the technical differences between the old and new systems, also makes HD IP Camera is also facing a number of obstacles and difficulties in the application. For example, system updates, there is a mix of analog cameras and HD IP Camera hardly compatible; addition, high-definition image transmission of high-definition network camera is the need for greater network bandwidth; massive high-definition image data so that the rapid expansion of storage space; massive data retrieval focus, coupled with some program designers reasons for higher network camera recognition, making high-definition IP Camera encountered great obstacles in the promotion process.
