With the continuous improvement of pixels of megapixel network cameras, it also brings with it the problem of video occupying more bandwidth and storage. Although current manufacturers have correspondingly broadened the bandwidth and increased storage space, the useless data generated during the video surveillance process has increased the burden on the entire monitoring system and caused troubles for the contractor. Therefore, how to improve the stability of bandwidth guarantee products has become one of the focuses of the R&D of manufacturers.
"This year we have a new "SVC"--extended video coding technology. This technology obtains a complete data stream from the network camera and transmits it to the back-end RELAYSERVER. According to the visitors' specific needs, it provides different screens. The combination of data rate/rate/resolution for the visitor is worth mentioning: “AAS†– Smart Bandwidth Adjustment Technology, which reduces the frame rate from the original setting of 30 frames/second when the video surveillance screen is at a standstill. For 1 frame/second, and when the object motion appears on the monitor screen, the frame rate will quickly return to 30 frames per second, and the entire process bandwidth changes only about 3 Mbps, and the device is in the “silent†state while the frame rate is reduced while storing , real-time browsing and screens are still continuing. This technology can save 4/5 resources for the entire system, said Zeng Chunwei, a technical engineer at Shanghai Pesston Computer Technology Co., Ltd.
