The disadvantage of the HD IP Camera

The disadvantage of the HD IP Camera
HD monitoring time has come, HD IP Camera almost become the mainstream surveillance products, does not know that HD IP Camera has its unavoidable shortcomings.
      
The first is bandwidth usage. 1080P HD IP Camera, 5 times the amount of information D1 camera, the optimized encoding compression, bandwidth usage about 2M, higher than the D1 Network Camera more than doubled. If the internal network is also not a big problem, but the long-distance transmission, you have to use the line, ADSL is not good enough.
      
The second is occupied by the large memory capacity. 2M stream, each image per hour to be occupied by the 0.9G space, the same higher than D1 Network Cameras, more than doubled.
      
Again is demanding on the computer, because the decoding of high-definition images to spend more CPU resources, decoding a HD Network Camera, roughly equivalent to the decoding four SD Network Cameras.
    
In addition, some high-definition IP Camera illumination is less than standard definition. Here mainly refers to most of the CMOS HD products, but this problem has been a significant improvement in, and before long, this problem does not exist. CCD high-definition Network Camera does not exist the problem of illumination, but the cost is too high, it is still CMOS for mainstream products.
      
In summary, storage, computer requirements, which can be ignored only increase the cost of a little. Bandwidth problems, not a problem in a local area network (LAN), wide area network or a major obstacle. Illumination problem is solved step by step, indoor use infrared light to basically solve the long-range view of the scene outdoors, then use the CCD HD Network Cameras as well.
      
Even HD IP Camera these shortcomings, but we still have a lot of ways to circumvent some of the problems such as bandwidth, even if there is not a good solution, but to the development point of view, it will certainly be solved. At first our computers to 1M of memory, at least 1G. The speed of development of science and technology can be seen far beyond our imagination. Friends, with the development of the attitude towards the new things, the courage to do the beach-goers of the times!
