Megapixels network camera pixels the higher the better?

Megapixels network camera pixels the higher the better?
Many of the works in the exhibition feeling megapixels network camera the exhibition various manufacturers of digital ring, 1300000, 2000000 too common, 300 million, 500 million or 16 million pixels have the show. Well, megapixels network camera is not pixels the higher the better?
Megapixels network camera is a very complex product, like the barrel from the lens, photographic original, chips, transmission, etc., any piece of plate gap will affect the rendering of the image. "The higher the pixels of the camera screen is not necessarily the sharper the pixel is just a manifestation of a quantity, the quality of each pixel is the key to determine the image quality. Some manufacturers do each pixel quality, its 1.3 megapixel camera may be even better than some 200 million camera image quality. "
In addition, works in the application should not blindly pursue the number of pixels of the camera should be combined with their actual needs and application environment to select millions of HD IP Camera. "Monitoring megapixels camera is different from an ordinary camera really applicable or practical million cameras should be between 1000000-3000000, especially 720P and 1080P, which is more in line with the existing network transmission, decoding capability, as well as storage space, integrated use of the environment. "
Megapixels network camera is very expensive?
Engineering costs, product prices has been a the Contractors concern. Megapixels network camera from its inception, the price has been Contractors promotion of difficulty to the user, but the high price of megapixels network camera does not necessarily mean that it is very expensive. "In the broad environment is relatively stable areas, such as city streets, parking lots, squares, etc., due to the megapixels network camera than the SD camera monitoring area wider, the image clearer, you can use a megapixels camera instead of several standard-definition cameras, money but spend less. " In addition, many manufacturers have also introduced different price megapixels HD IP Camera, product prices closer to the SD cameras.
Megapixels network cameras have higher requirements for transmission, storage, decoder, and transformation projects cost is difficult to avoid. "In old Lee occasion, the proposed works to New monitoring points used in all HD IP Cameras, at the same time, some of the original control points, you do not need to overthrow once the project has been built to select the correct video monitoring and management platform, whether it is high-definition monitor new or existing analog monitoring points are centralized monitoring and management, to the maximum extent possible to protect the user's investment. "
Megapixels network camera where can?
The development of any product requires a process megapixels network camera is in the development stage. Megapixels HD IP camera use is more concentrated in the low light, corner sharpness issue in overcoming megapixels network camera night vision effect is uncertain shortcomings, some manufacturers have adopted a mandatory color to black and white screen, slow shutter The speed of the ways to solve. But in such a way there are some deficiencies, reduce the quality of the images collected, the loss of high-definition advantage; Once the shutter is slow, prone to the problem of monitoring objects smear. "Although many manufacturers are in the camera processor to improve, but in low light issue, millions of HD IP Camera still has its disadvantages, some light variation, just do not pay attention to the needs of a wide range of monitoring the details of the place, If the highway is not suitable for use megapixels IP Camera is mainly used in factories, bayonet, financial and other places. "
Products very clear, why after installation effect is much lower?
"This is mainly static images and dynamic images between misleading. General dynamic video processing than the static image processing requires a higher data processing capabilities, there are network cameras, dynamic video processing reach megapixels level, or can not achieve full frame rate. "
In addition, the demonstration of 5,000,000 pixels or more cameras, more inclined to capture instead of shooting. , 5 megapixel stream from the practical, not suitable for transmission through the network, so the resolution to show what equipment is still a problem. From a practical 2-megapixel Full HD 1920 x 1080P, the bit rate to 4Mbps to 6Mbps, standards-based H.264 compression, is currently the most valuable resolution in the security market.
A product is good or bad, and ultimately rely on the application of the effect of the decision. Million HD IP Cameras as well, although the pixel technology continues to improve, on a technical point of view should be given applause, but if you can not meet the contractors, the practical application of the user, then the pixel can only foam. Megapixels network camera suppliers technically improve at the same time, it should sink in the heart to listen to the voices of contractors pass the correct concept to engineering companies to produce their products, better services for engineering companies is the future of millions pixel HD IP Camera development trend.
