移动监控应用领域将如何面对高清问题（How will mobile monitoring applications face HD issues）

移动监控应用领域将如何面对高清问题（How will mobile monitoring applications face HD issues） The survey of the lack of high-definition network camera in the application reflects real-time and high-definition display problems, non-standard protocols, resulting in difficulty in integration, no unified format standards, the three most reflected. The signal real-time display on delay is the main reason for the high demand of products of high bandwidth, IP video signal flow packet over high packet loss rate, bandwidth shortage caused by the delay, and the current Chinese network transmission more expensive... At this stage of the IP million HD (720P@30fps) transmission can pressure at 2-3Mbps, while 1080P@30fps can also control pressure in bandwidth below 6Mbps, the transmission and storage burden of IP HD can be said to be greatly reduced. But with the conventional transmission monitoring equipment as an example, the current 720P specifications based on the calculation, the stream is about 2 times of D1, the bandwidth is about 3M, and take 1080P calculated bit streams is 5 times that of D1, the bandwidth is about 6M, the storage disk capacity is the same. As the high-definition video equipment investment compared to the past, CIF and D1 cameras will increase exponentially, other ancillary products are the same, especially the storage equipment costs increased more. At present the relevant policy around the promotion of the video surveillance equipment most require definition above D1, promote the application of HD mainly depends on large government related projects, the local government in the land finance difficult to continue under the pressure of funding is very tight, funded by the government or government funded, need to monitor the implementation of the project (such as safe city intelligent transportation, safe campus, safe hospital etc.) number, a huge amount of funds required, had to reduce the layout of the high-definition camera. With the construction of safe city to the 3 and
