HD agitating lens market expands monitoring applications

High-definition lens in the design, assembly process, processing accuracy and Other aspects than the ordinary lens requirements are more stringent, in the process of extensive application of high-definition lenses, some technology is not in place, the standard is not up to standard lens manufacturers are likely to be in this high-definition The lens is eliminated and the competition in the HD lens market share in the security industry will be concentrated among a few brand lens manufacturers. The competition among the lens manufacturers is even more fierce, and they are also facing more challenges. The lens manufacturers are constantly strengthening their R&D efforts in respect of security monitoring requirements at different levels.

From the actual use of the effect point of view, high-definition lens image quality display more favored by the user, different lens products show the effect is completely different. Take traffic monitoring as an example. By using a high-definition camera, you can not only see the license plate and the driver, but also can see the details of the driving situation in the car. Once a traffic accident occurs, it has a great effect on the investigation and investigation of criminal cases by the Public Security Bureau. According to Gu Chenggang, Phoenix Optical Brand Sales Minister, “The e-police in intelligent transportation has the highest requirements for the camera. Due to its special needs, it needs to use a large 2/3-inch 5-megapixel camera and has very strict distortion control on the lens. With clear results, good center-to-edge brightness ratio, it also requires sufficient depth of field, convenient focusing, and cost-effective consideration."

According to Zhang Lianshan, Fujifilm's optoelectronics division, “Infrared and day/night functions have been added to the original 3 megapixel HD lens. This is the focus of the company’s launch of a series of products this year; in addition, many cameras are now used. It is a non-standard target, such as 1/2.7, 1/2.8, or even 1/1.8, so the company's focus this year is also to target this non-standard chip, to make the target surface bigger and make our lens target You can gradually cooperate with these cameras."

In addition, for different areas of the security industry, such as road monitoring, intelligent transportation, safe city, factories, hospitals, etc., the demand for the lens is not the same. For example, fixed-focus lenses are generally used in indoor, hall, traffic jams and other fixed-distance surveillance sites; manual zoom lenses are generally used in outdoor areas where monitoring distance is not fixed, factories, schools, road traffic, etc.; general application of power zoom lens In outdoor long-distance occasions, such as urban security, high-altitude, highways, railways, rivers, maritime, border defense, forest fire prevention and so on.

In the face of such a complex demand, some lens manufacturers can only look to the world. In fact, the lens market share of the security industry has long been divided by several lens brands at home and abroad, and it is very difficult to change the existing pattern. However, there are also some lens manufacturers taking a high-definition ride, the opportunity to launch high-definition lens brand. Liu Liyan, a sales manager of Tuilei Optical CCTV lens, mentioned: “With the advent of the security HD era, the market structure of the lens will be affected to a certain extent. Whoever continues to innovate in the field of high-definition lenses, do not fool, not fraud, who can go Faster and more distant. There are also Japanese brands that focus on high-definition lenses in the past two years. Although brand awareness is not high, they still can quickly build a world by relying on a relatively comprehensive high-definition product line."
