Ease insufficient bandwidth HD monitoring solution

Ease insufficient bandwidth HD monitoring solution
HD IP Camera to get large-scale application, in addition to passive network operators expect to make some adjustments, but we need to take some proactive alternatives to alleviate HD IP Camera network bandwidth is not enough of contradictions.
The use of advanced video compression standard
Active use of advanced video compression standard, to ensure that with the least amount of data to achieve the best image quality, but by the image coding technology and intelligent technologies, the use of local coding method that can considerably reduce the required HD image transmission network bandwidth. Currently, there are three mainstream compression format, namely, JPEG, MPEG-4, H.264. JPEG is a single-frame image compression, a single picture works best, but a large amount of network bandwidth resources; MPEG-4 and H.264 is a continuum between the frames compressed. Wherein the most popular compression formats H.264 highest compression efficiency, H.264 compressed video data through the network during the transmission bandwidth required less.
Provide dual-stream support
In the realization of high-definition local recording while using dual-stream technology can both reduce the long-distance transmission bandwidth usage and ensure that local better image quality. HD IP Camera remote monitoring environment that provides all the way to high-bit-rate HD stream for local storage, such 720P/1080P coding, all the way to low bit rate streams for network transmission, such as QCIF / CIF encoding, taking into account local storage and remote network. Flexibility to choose according to network bandwidth stream format, to local HD storage, while the back-end low stream network transmission. Users can obtain in the case of limited network resources, to ensure stable operation of the transmission system.
Smart technology to improve added value
Smart technology can improve monitoring efficiency, it can bring value to more than that, through the pre-coding and intelligent analysis, embedded intelligent analysis module definition network camera can grab from the source of valuable information and then spread to the background, can reduce the transmission pressure, truly effective transmission. HD IP Camera capture images on their own to analyze and judge, and the alarm signal is transmitted to the back-end system, which is different from the smart technology to transfer images to the back-end system and then analyzed by software alarm mode. Conventional method needs to occupy too much bandwidth and storage space, and as the image signal during transmission loss exists, prone to false alarms. The HD camcorder since all signal processing inside the camera in the preceding paragraph, the signal is the most complete, so greatly enhance the accuracy of the alarm, while reducing bandwidth.
Complete front-end caching technology
Front-end caching technology designed to ensure the equipment images are not lost. HD camcorder itself data storage capacity is limited, depending on the communication transmission and back-end storage devices. We can front-end caching mechanisms designed to prevent loss of data communications failure. For example, in high-definition network camera system design, optional on-board memory or other storage device, and supports offline. In the case of abnormal network interruption, data can be temporarily stored locally, such as the network returned to normal after the server returns. But also through network technology, network front-end cache temporarily interrupted until the network is restored automatically upload recorded data, thereby ensuring the integrity of the video.
Establish and adhere to industry standards
Monitoring market is necessary to unite the manufacturers to develop some of the prevailing norms, seeking common ground while reserving differences. Currently Onvif, PSIA standardization organizations such as the emergence of people see video products and systems standardization of hope. Video Surveillance "plug and play" era believed to have been far away.
Summary: surveillance network camera represents the future of surveillance cameras. At this stage, our optical transmission system, represented by a high-speed network transmission technology applications are gaining popularity across large geographic range ultra high-speed backbone network and high-speed local area network has become the norm facilities, a large stream through a network of high-definition images real-time transmission has become possible, but also constantly tariff reduction. These are high-definition monitor to open a broad space for development.
