Why do you need to use SDI converter in HD surveillance?

At present, many HD monitors in China use HD-SDI high-definition digital serial interface to transmit video messages associated with transmission. Since HD-SDI may directly expand with the imitation flag monitoring system, this is about some monitoring sites of some historical history. It may be possible to reduce the cost of improvement as much as possible. With the growth of skills, video skills grow fast, video interfaces are also more and more, such as HDMI interface, CVBS interface, VGA interface, DVI interface, etc., then use in the defense monitoring How do we blend these different video settings into this type of video interface? 

 The fortification monitoring system often divides the five departments. In this case, there are three departments that touch the transmission of the banner. The first is the front-end search, the banner transmission and the monitoring of the message. So in these three departments, our front-end search may take HD. -SDI high-definition camera, using this kind of camera, it is good to shoot high-definition surveillance images and capture the fine-grained department. In the flag transmission department, it is to sing the audio and video messages, manipulation and shape flags of the front-end. It is possible to use optical fiber for transmission, or use the network to carry out transmission. The overall situation may be implemented by the actual situation of the license. The cost of the two is different. If the network transmission is used, then the corresponding video encoder product is required. Then there are some plans that can be adjusted in the display department. If the HD-SDI video flag is transmitted, and the SDI monitor display is relatively expensive, and the intention is to obtain a compromise plan, then the display of other interfaces can be considered. The SDI alternator is used to transfer the SDI video flag to other associated video interfaces.

Except for the above situation, there is another kind of situation. For example, if a high-definition camera such as an HDMI camera is used at the front end, then the HDMI digital flag is transmitted, and the transmission department adopts SDI-related cable transmission. It is possible to use the HDMI to SDI alternator.

 The above is why the HD monitoring boundary needs to use the SDI converter related message. In summary, the SDI converter is also a kind of dedicated video processing setting, there are some parameters and other technical aspects, so the requirements are adopted. Ask the associated skills staff to get a better service.
