How to build HD surveillance system for a small factory or store?

How to build HD surveillance system for a small factory or store??

The surveillance products are rapidly changing to high definition megapixel IP network video surveillance, old standard definition analog camera + DVR mode is out. You can use the following two type solution to build HD(high definition video surveillance system) for your small factory or store.

1.    HD IP camera + NVR (network video recorder) solution: it is use 1080P 2 megapixel IP camera with IR function and 1080P high definition embedded Linux standalone NVR(network video recorder) + HD monitor, you don’t need to buy additional computer. But you can use mobile phone and computer to remote view the video. The features is based on open IP network, any computer and network device can access any camera, it is open and flexible. Now IP camera and NVR manufacturer has resolved the network setting problem, you don’t need to do complex network setting.

2.    HD analog camera + HD DVR: If you don’t use open network system or you don’t want to do any network setting, you can use analog HD camera and DVR, now there are many HD analog camera and DVR, its use coax cable to transmit the video.


Budget: if you directly buy all products from China IP camera and NVR, switch manufacturer, or you buy its from online store, you can save a lot of cost. For example, Sysvideo as China professional IP camera and NVR manufacturer, China’s price is only half of other countries local market.

H.265 IP Camera and H.264 IP Camera difference

As increasingly demand in users on the surveillance video quality, high-definition video applications in the security surveillance is becoming increasingly popular, which brought a sharp increase in storage space and costs. Compared with the H.264 encoding technology is now being used, a high compression rate characteristic of H.265 can save about half of the storage space, thereby significantly reducing the cost of storage of the video. Compared with H.264, H.265 best advantage is under the premise of maintaining the image quality, make data transmission bandwidth is reduced to half of H.264. At the same time it supports up to 7680 × 4320 resolution, so even 2160P even higher levels of ultra-high-definition video can be encoded by H.265  format.

Due to limitations H.264 macroblock, resulting in the video processing load is also increased significantly. HD eventually face the problem of the high frequency treatment, bloated feeling. And with respect to the H.264, H.265 macroblock type in the full lifting of a hierarchy, the original module type 16X16 raised to the highest 32X32,64X64, even 128X128 macro blocks. Thereby reducing the number of high-definition digital video macroblock, the macroblock is used to describe the content of reducing the parameter information, and the transform block size corresponding shaping expanded repeat the compression efficiency of the device.


In addition, H.265 is also used to update the motion vector of the test. In addition to the above-mentioned aspects, H.265 achieve a more breakthroughs in multicore parallelism ,in some new technology under the WPP, such that it can be a higher degree of parallelism in order to meet a variety of needs under the premise, can achieve high compression efficiency in the work process.

 

Through technical analysis above, we find that H.265 has a lot of technology to over than H.264. In terms of functionality and performance, H.265 is better than H.264 , H.265 come to world just a time .

In short, H.265 bring new hope  to us for high-definition monitor, many areas can not wait  for it. From this perspective, although the current application status for H.265 popularity is still very far away, but birth of H.265 is also destined ,and for problems it may bring also  waiting for solve, but H.265 in the future dominance is the undisputed facts.
