The largest market share is a megapixel IP camera market is said to have appeared 8 million pixels of surveillance cameras. However, in the HD era, the higher the pixels of the camera, the effect will certainly better?
In the survey, the largest market share of megapixel IP cameras, accounting for about 65%, the 2 million accounted for 15% the 3 million accounted for 10%, 4 million and 5 million respectively, 5% each . It is said that the market has 8 megapixel network cameras. However, in the HD era, the higher the pixels of the camera, the effect will certainly better?
High-definition biggest advantage is that pixels high, high-definition, but that does not mean that the higher pixel on the better the performance. Light sensitivity, i.e. the illumination performance is extremely important parameter in another of the camera. Under in some photoreceptors effective area, pixel size and low light performance is often inversely proportional to that the higher the pixels, the worse the low light performance. Security Industry camera installation environment is extremely complex, and the light is not good many surveillance applications, therefore, should also be considered in the pursuit of high-pixel camera, while its low light performance.
In fact, the simple security monitoring camera pixels is not difficult, but to consider the hard disk occupy network bandwidth and video compression to deal with stress, low light, large data processing stability, back-end host and supporting, the current situation can not excessive covet pixel too high.
The explosive growth in high-definition products today, many security manufacturers regarded R & D focus on the front-end camera pixels wide dynamic, low-light performance, research and development of back-end products, but not enough. HD effects presented, the front camera and back-end products, software perfect match to achieve. For security manufacturers to increase R & D front-end product, and should be strengthened on the research and development of back-end products, and strive to front-end and back-end products done best match.
