Seen through the network HD clear outlook upcoming era
A sensor chip demanding
Over the years , high-definition Network camera has become a hot word in the field of security fired . It seems in the current network monitoring , if not with "HD " word , then almost had earlier declared the era of the fate of being eliminated . However, shouting Network HD for so long , but also enjoy a lot of network HD , but if we want to suddenly asked : Network HD in the end is what configuration ? It also more than ordinary standard definition cameras to achieve what is progress? Here , we have to thin the HD IP camera "Anatomy " to see the Network camera in the end has a kind of magic.
A sensor chip demanding
For a surveillance camera , its sensor chip is undoubtedly the most important. Under normal circumstances, we often find the shadow of the CCD chip in an ordinary analog camera. But for high-definition IP Camera , it may not have such a " picky " the. Currently , high-definition cameras for both the CCD chip or CMOS chip , it belongs to an application surface relative to the average state.
Therefore, it can be expected that in the future for a long period of time , these two types of sensors will be a major force in high-definition camera. Only because CMOS cheaper to produce more convenient features, so in a relatively low-cost surveillance cameras , we always can often see its shadow . And because the CCD sensor is more sensitive responses in color , clarity and more good, so for some of the higher -pixel , high-end cameras integrated more capable , we will see more of the shadow of the CCD chip .
In addition , the sensor chip size is also very important but often overlooked aspect of the different sizes of lenses, the lens has a correspondingly different amount of light . So high-definition Network camera , the lens with it is very important , if not with words , it is likely both will be other HD efforts destroyed. Thus , with the most appropriate lens , it is actually an important part of the sensor can not be ignored .
More delicate image processing
Since it is a high-definition camera , then the corresponding picture processing capacity is certainly indispensable. For a high-definition IP Camera , the quality of the decision by many factors , but the most important manifestations mainly lies in three areas: compression technology , the effect of TV lines , and the role of the ability to stream .
Ability to enhance compatibility terminal control
First is compression technology. As we all know , after experiencing a long-term development , MPJG-4, and H.264 is our current most commonly used compression techniques. If you compare the features from the horizontal , the latter for the continuity of the video can provide more help , and for a single video imaging capabilities , the former has a stronger performance. However, as a rising star in compression technology, H.264 overall performance is still a lot higher than MPJG-4 . And with the advent of H.265 technology, we have reason to look forward to in the compression part , we can achieve a more perfect.
In conventional surveillance cameras , the 480 line is a well-recognized definition baseline. With Sony, Samsung and other high-end devices continuously released. Numerical HDTV line is constantly refreshed with . In the current market , more than 600 lines of surveillance cameras is no longer fresh. However, the face of the current 1000 line has grown to hundreds of TV resolution, I am afraid that the current definition cameras, does not make us wait too long .
HD Network camera
Because of the lag is also a complex network transmission processing time HD equipment unavoidable problem . Now, with the development of the overall IP Camera technology, the delay has been able to control the basic equipment within 300ms, thus maximizing technology ensures real-time . For a more extensive network monitoring applications is also a very effective foreshadowing .
Ability to enhance compatibility terminal control
As networks become increasingly widely used in high-definition equipment , in order to obtain a more convenient control and maintenance, how to improve their products for compatibility with web browsing devices has become the focus of attention of many manufacturers . From the current application trends, replaced by common browsers has become a lot dedicated software development orientation of the device , which is used to maintain user and device , compared to the traditional common devices are undoubtedly a revolutionary advancement .
At present, China 's high-definition network surveillance system is actually still in a very early infancy. But as the future pillars of the mainstream that we do not already become an indisputable fact. But especially in the SDI products come under the same immature status quo, which is both a challenge for network HD , but it is also a facilitator . In such a competitive environment and needs , we have every reason to believe that the network will in future high-definition applications, bring us more surprises.
