HD triggered megapixels surveillance camera disputes
Is popular with a surge of high-resolution boom megapixels digital camera lens became the most important accessories. In many cases, the end user wishes to obtain the image quality and higher resolution video quality. However, there are too many monitoring systems manufacturers and vendors still do not realize that, for megapixels IP Camera, the lens is not simply the lens. In China, some security vendors have opened the Pandora's box of megapixels lens.
Irreversible trend
From 2010 onwards, HD high-definition equipment has begun to be applied to the basic monitoring facilities, network upgrades and broadband broaden let megapixels see room for growth in the Safe City project. According to statistics, megapixels lens output accounted for 30% of the total output of the lens, reflect this phenomenon can, the next 3 to 5 years HD lens in the market will be dramatically increased.

Obviously, megapixels IP Camera demand continues to increase, the traditional optical imaging device can not give full play to the CCD HD; megapixels HD IP Camera lens with the traditional analog cameras, high-resolution cameras with high quality lens. Dealer or user, the future trend of megapixels is no doubt; many manufacturers, high-definition contrast normal lens is more conducive to monitoring.

There is no doubt, a standard analog camera lens megapixels lens imaging results are very different. In practical applications, such as license plate recognition, face recognition using a HD IP Camera, thereby obtaining a high resolution image and presents some of the necessary details.
Traffic, for example, the use of megapixels IP Camera can not only capture the license plate information, or even the appearance of the crash can be seen clearly. The event of a hit-and-run problem, high-definition images can help the police quickly locked the suspect. In addition, high-definition probe can cover more space, you can replace multiple traditional analog cameras. The initial construction cost savings, while also able to reduce ongoing maintenance costs.
In practical applications, high-definition lens digital zoom the image to enlarge, including the part of the image edge. Unlike monitoring fish-eye, fish eye is the use of ultra-wide-angle lens, View ultra-wide field has a better image resolution, the situation of a barrel distortion.
Technical challenges
Non-edge definition is premised on the image resolution continues to increase. Aspherical lens plays a very important role in the case of a measure of edge sharpness. Aspheric lens can be effectively added to the edge enough fiber largely avoid the blurring of the surface of the dome. However, some manufacturers use a small focal length lens, of the aspheric lens, the the marginal glass must be carefully polishing, the reason is because of the particular material, can not supply.
Even so, the grinding technology is still bottlenecks caused to real-world applications. Rarely been seen in the mass production of aspheric lens coated with a layer of expensive materials, of course, is a selling point, but also a necessary technical indicators.

Typically, different from the ordinary lens megapixels resolution and edge sharpness, aspheric lens in addition to the central clear edge to maintain a high-resolution imaging through a special optical design to achieve ultra-low dispersion lens.
In general, the lens manufacturers will focus on three areas: sharp, the lighting and the integrity of the image. These are also the Buyer test standards. Megapixels lens requires strict assembly and complex materials and equipment program.

Domestic test of the overall strength of the lens
Compared to a single product, than the natural lens manufacturer Tamron Japan's Fuji. It had to be sure, the Japanese lens in purity, to spend the accuracy and layer technically better than us. But compared to the overall strength of the lens in Japan, mainly domestic. The domestic purposes Walking customized service and cost-effective cost control, management easier.
HD digital high-definition prevalent in the security industry, to allow more users to understand the importance of image quality. When selecting a product, the overseas Mao judgment is a comprehensive cost-effective, even if the lens of Japan in China also has a price advantage, but the performance stability should not be ignored.
Surveillance camera lens can mix and match
Accordingly, by the intelligent edge device may achieve better image quality, high-definition video in low broadband transmission and can reduce the storage capacity.
Megapixels lens design still faces enormous challenges, higher than the ordinary lens assembly process and the accuracy of the machine. In any case, megapixels aspherical lens structure characteristics to achieve true HD plays a vital role. So far, it has achieved it comes to network monitoring Full HD front end to the back-end equipment. HD-SDI still stuck in the front-end solutions provider. Megapixels lens mature HD IP Camera solution, you need to completely solve the back-end issues, through the continuous upgrading of technology, this desire is just around the corner.
