Which camera and HD SDI million more cattle
With the continuous improvement of security technology, technical content security products is also greatly improved from the original CMOS to CCD, then from analog cameras into network camera , and from millions of ultra- high-definition network camera to SDI SD cameras . As video surveillance network camera manufacturers , if a little inattentive , will be followed by a new technology far behind.
Security camera industry because a lot of low-end products into the market . Most companies do start feeling was very difficult. Then high tide will follow. The market also spared a . Definition of further development, not only the front-end video capture device replacement has changed , thus bringing high definition video data traffic surge , but also on the back-end storage management equipment put forward higher requirements. It is said that the rapid development of high-definition , and finally inevitably encourage IP Camera replace analog cameras , NVR replace DVR, from the whole industry to see, HD network does have a distinct advantage , because in this era HD is an inevitable trend . But the industry also so few can really achieve positive overall solution , the lack of or a lot . Each company under various slogans and sang their own songs definition , small businesses also followed the booing , a price war will start , the market also shaken. What is plug and play, what remote viewing , and what low noise ? , And other customers with the future is not only to find what we want . In addition to satisfactory results during the day outside the definition of the other may only sing .
2012 HD-SDI camera turned out , making the field of video storage devices and the emergence of new opportunities and challenges, the network effect can be comparable to HD . Fully meet the high 200W1080P effect. Let us look to the eyes and HD-SDI and HD. Because the simple and convenient, and all aspects of analog cameras entirely consistent . So HD-SDI DVR storage needs in this definition came into being . In SDI-DVR surveillance system management device as more prominent advantages , first in the current platform compatibility with other devices is good , SDI cameras only through coaxial cable can directly access SDI-DVR, NVR did not like the video data after repeated compression and conversion , better contrast picture quality , but also to ensure stability as the traditional DVR . But the overall price more expensive than the high-definition network camera half.
After HD-SDI cameras to the network, the difference between analog cameras feature HD-SDI camera is a digital image signal obtained by the image sensor chip through the ISP to do image processing, is converted into uncompressed HD-SDI serial data, and then transmitted through the cable ; IP Camera after the image is also a digital signal obtained by the image sensor , and then do the image processing chip through an ISP , and then compressed and then transmitted via Ethernet . Since the HD-SDI camera without compression chip that can reduce the cost of this session .
If only from the point of view of the effectiveness and stability of the words . So SDI undoubtedly more dominant than the network cameras. But speaking from the words of the cost price , SDI cameras simply can not match. Now most of SDI HD cameras are just part of the Government and other projects to use. SDI to realize civilians, still have a long way to go. Therefore , we look forward to the next technology upgrades and updates to bring us more affordable and high- quality products it.
