从“水晶球”中看高清网络摄像机的未来 - 安防知识网

2010年5月的时候高清已经做好了准备，但是网络视频监控市场向更高分辨率发展的步伐有多快呢?2010年大家肯定看到了高清和百万像素网络摄像机出货量已经大幅增长，然而，标清网络摄像机的出货量仍然比它们的更高分辨率的同行来的高，约为4：1。

　　在IMS Research的《世界CCTV及视频监控设备市场-2010年版》报告中，预测在2011年HD和百万像素摄像机的出货量可占到网络摄像机出货总量的30%。展望未来，IMS Research预测高分辨率安防摄像机当中，HD摄像机所占比重要高于百万像素摄像机。

　　高分辨率摄像机的需求不断增加，HD解决方案让人尝到甜头。HD可以提供更高的分辨率，但并没有达到让存储和带宽的成本变得难以控制的程度。此外，在消费电子领域中对高清的偏好已经带动了视频监控市场对高清的需求。

　　高清网络安防摄像机的销售量大大超过标清网络摄像机的临界点在什么地方呢?IMS Research预测，到2015年，超过网络安防摄像机的出货量的60%将是由高清和百万像素贡献的。

Looking Into the High Definition Crystal Ball

　　2010 may have been HD ready, but how fast did the network video surveillance market move towards higher resolution cameras? 2010 certainly saw significant growth in the number of HD and megapixel network security cameras shipped; however, standard definition network camera shipments still outsold their higher resolution counterparts at a factor of four to one.

　　In IMS Research's “World Market for CCTV and Video Surveillance Equipment – 2010 Edition” report, HD and megapixel cameras are forecast to represent nearly 30% of network security camera shipments in 2011. Going forward, IMS Research forecasts an increasing proportion of high resolution security cameras will be HD rather than megapixel types.

　　The requirement for high-resolution cameras is increasing and HD has emerged as the resolution sweet sort. HD offers increased resolution but not to the extreme level where the cost of storage and bandwidth becomes unmanageable. Furthermore, the preference for HD in the consumer electronics space has driven the demand for HD in the video surveillance market.

　　At what point will the tipping point occur when a larger number of HD network security cameras are sold than standard definition network cameras? IMS Research forecasts that by 2015, over 60% of network security cameras shipped will be HD and megapixel resolution.
