Mainstream products on the front end equipment, "all-in-one" has become another important domestic camera development indicators, "all-in-one" development so far, however, there are actually its technical development space, especially on the lens application development field, as the technology of ascension and the market demand, the development of the "all-in-one" space there is improvement, diligence. We will look in the technology principle and application of all-in-one, for all-in-one PC, what can be improved.

Define and product advantages

First let's take a look at the actual definition of all-in-one, "all-in-one" is short for integrated automatic focusing the camera. Refers to the camera body and special zoom integrated together, which has the function of automatic focusing and lens changing times the camera.

"All-in-one" will zoom lens and the camera together, and have the function of automatic focusing, through the fuselage control button or remote control mode, according to the observation of the picture is the object of the characteristic of flexible image vision and the change of the close shot Settings, greatly simplifies the camera installation and operation. As the front end of the product monitoring system, all-in-one integrating the function of the camera, lens, and have the function of automatic focusing.

The hardware part of the "all-in-one" mainly cameras and special zoom lens; Software part mainly automatic focusing, varying times technology. , of course, its USES include: cooperate with the use of intelligent ball (the current intelligent ball market demand is growing, especially the demand is larger in the "safe city" project) and yuntai using, electronic projectors use (this is monitor outside the market, the market demand is larger than the current security monitoring market at least) are currently the most demand of products.

In fact, "all-in-one" product advantage mainly lies in the fact that you can achieve 480 TV (or even 540 TV), high-definition graphics, with functions of automatic focusing; And has strong function of optical variable times, common, such as 16 x, 18 x. x 22, 23 x, 32 x, 35 x; This kind of product integration is high, the price advantage is obvious. While the current all-in-one products mainly include SONY (FCB 48 bp / 480-45 bp/bp; FCB - 980 bp model), HITACHI (vitamin k - S214ER / 274 er; VKS454ER model), LG, SAMSUNG SAMSUNG (SDZ - 310/300 type), CNB, Lin this several big, Japan and South Korea imported products, the brand is dominated the all-in-one product market of China, and become the mainstream.

"All-in-one" product deficiency

However, from the point of the overall technology principle, improvement and innovation of all-in-one thinking of have the following: 1, the hardware has shortcomings. Such as cameras, everyone know now are using 1/4 "CCD camera products, because the camera CCD target surface limit, makes the basic technical indexes of integration in the camera is insurmountable bottleneck. Basic technical indexes of clarity, intensity of illumination of the camera, signal-to-noise ratio and so on will appear different degree of application problems, such as technical parameters of nominal 480 TV horizontal resolution, the actual minimum only reaches 430 TV - 430 TV, color turn black minimum illumination nominal (SONY EXview HAD chips) 0.002 Lux, chip makers are original parameters is only 0.01 Lux/pro series, 1/4 "of the whole machine but how also can not reach such a low intensity of illumination. Even there is accumulation of functions, practical applications is not large, and in the actual application of citic to noise ratio of the difference is not obvious, also need professional test equipment.

In addition, in terms of the lens, the lens is derived from the original in use all-in-one home video camera (that is, we often say "DV"), the camera is not tailored for monitoring "all-in-one" product. Now use the lens of the product is 1/4 "on the surface of the target product, in the lens of basic technical indicators such as: F value, are insurmountable bottleneck in the field of view Angle. Cause lack of light, of the application of viewing Angle is narrow small, etc.

For example: a lot of aspherical lens in the field of today's CCTV lens, infrared corresponding new technology, so that the direct effect is the F value greatly reduced lens, from the usual pro series, allows to F0.95, F1.0, intensity of illumination of the same light camera significantly improved, and the infrared lens focus when auxiliary light source is not offset, clear images of the night and day also.

And in software technology, high-end brands such as SONY, usually HITACHI automatic focusing has been doing very well. Basically the focal length can be change, automatic focusing action one can focus on clear, all-in-one products of other brands in terms of automatic focusing speed has improved space.

All-in-one alternative thinking of competitive advantage

As said earlier, under the current all-in-one technology platform structure, certainly has the potential to improve camera hardware, after all the camera itself has 1/4 ", a third ", 1/2 "series of CCD, 1/4" in all-in-one CCD can do, a third ", 1/2 "CCD certainly can do it better. The problem lies in the lens, because without a third ", 1/2 "on the surface of the target, so must be made to order. Once the lens technology bottleneck breakthrough, cooperate with the CCD 1/3 ", 1/2 ", the function of the all-in-one will be substantially improve. To develop a third ", 1/2 "on the surface of the target, the investment of time and development cost is opposite bigger, to strength is strong manufacturer to operate.

Therefore, in the current all-in-one technical structure framework, a third "all-in-one product or has the potential to achieve, and it is likely to exist in most is 1/4" all-in-one hardware configuration under the condition of limited, as China's security market a "dark horse", high-end customers and meet market demand for more powerful all-in-one.

Overall, the current "all-in-one" product is derived from household (DV) camera machine concept, is not is tailored for the needs of security monitoring products, so, from the perspective of security dedicated, launched a special products suitable for the security monitoring demand will greatly welcome by the market.
