The security industry is experiencing the development of “digital, networked, high-definition, and intelligentâ€, and the all-in-one movement is no exception. With the improvement of the performance of the high-definition integrated machine movement, the high-definition fast-ball machine and the integrated camera and other related products can be upgraded, and the HD integrated machine movement market is ideal. Similar to the traditional analog integrated movement, the HD integrated machine movement is more suitable for long-distance monitoring, and is a better choice for monitoring of traffic, ports, and safe cities. After experiencing a major breakthrough in technology, the demand for high-definition integrated movements has increased dramatically.
Market growth accelerates the demand for high definition
Millions of high-definition all-in-one movements are developing rapidly. Many manufacturers with R&D strength have invested a lot of manpower and financial resources to develop and produce one-piece movements, and the Million HD integrated machine movement can be used in a variety of product forms. Such as high-definition fastball, high-definition infrared ball, high-definition integrated camera, high-definition cloud platform, etc., so its market prospects are very broad, and the amount is huge. Thanks to the high adaptability and flexibility of the Million HD integrated machine movement, it can be applied in many industries and fields, such as safe city, road monitoring, community monitoring, plant monitoring, campus monitoring, etc.; in some sub-sectors For example, the public security industry, the power industry, etc. are involved.
High-definition screen and full digital breakthrough
Simulated movement on the market 1. HD picture; 2. Real digitalization. Products still dominate the market, but from the development of the industry and a series of trends of manufacturers can be informed that the role of high-definition movements in the monitoring market is increasingly increasing. Compared with analog movement products, high-definition movement products involve changes and upgrades of multiple module technologies, but in essence, the advantages of high-definition movements are nothing more than two points:
Sensor, lens, DSP core technology innovation
The hardware module structure of the HD movement is no different from the analog product, but the core hardware such as sensor, lens and DSP is a qualitative leap: the megapixel high-definition machine movement mainly continues the CCD sensor, the most representative Nothing more than Hitachi's DI-SC110-C130 megapixel HD all-in-one movement, this movement has a high-definition movement, its excellent clarity, depth of field performance, excellent low-light performance, telephoto zoom, one Launched the market, immediately favored by many high-speed ball manufacturers, one machine manufacturers, quickly occupied the market. However, the movement of more than 2 million pixels is mainly based on CMOS. Exmor CMOS, which is a high-sensitivity CMOS, is a high-sensitivity CMOS. Its low-light effect is comparable to that of CCD, which completely overturns the CMOS nighttime effect that people had previously imagined. Cognition
In terms of lenses, some manufacturers have begun to introduce higher-magnification HD lenses such as 22X and 28X to meet the market demand, but because of the relatively high threshold of telephoto lens technology, and corresponding to the ability to manufacture corresponding HD lenses. There are relatively few manufacturers, so the price is relatively high.
DSP is a key point to test the technical strength of each technology. The processing of 3A (automatic white balance, automatic exposure, auto focus) is an important indicator to measure the merits of a movement. Generally, the good manufacturer white balance function is used in various scenes. The control is very good, and the focusing speed is also very fast, no more than 1S during the day and night. In addition to 3A in the DSP part, there are also technological innovations such as wide dynamics, fogging, and intelligent analysis. Currently, there are manufacturers promoting it, but at this stage, the composition of Shantou is bigger.
HD important stability is still the key
As the eyes of the monitoring system, the stability of the movement is very important. With the advent of the high-definition era, in recent years, many high-definition manufacturers have emerged in China, and high-definition products on the market are also emerging one after another. However, due to the fact that domestically can achieve independent research and development, there are not many manufacturers supporting front-end products and back-ends. Most manufacturers use a third-party backend, which causes poor compatibility between the front-end camera and the back-end, which affects stability. Moreover, there will be a small number of high-definition movement manufacturers that have not done sufficient tests during the development process, resulting in numerous failures in practical applications.
The movement products need to work normally in various environments. Some prototypes produced by powerful manufacturers must pass a certain range of high and low temperature test, aging life test, and 30 days of faultless stability test to ensure each batch of factory shipments. The movement can achieve the best results, in order to ensure the stability of the monitoring system. Therefore, when choosing a high-definition movement product, a good brand will be better.
HD and smart are inseparable
Since 2006, the domestic security industry has shown an increasing trend of 45 degrees. Security products are changing in technology or in appearance. This is due to the domestic demand for security products, which is promoted by the government, media and enterprises. It has reached a new height, coupled with domestic full capacity for new technologies and new products, thus stimulating changes and innovations in technology and product requirements in the security market. Under the hurricane of high-definition, the HD all-in-one movement, one of the main forces, is naturally the same.
With the rapid development of high-definition sensors, DSP and other technologies, and the addition of more lens manufacturers, the optical zoom is getting bigger and bigger, the pixels are getting higher and higher, and the image resolution is getting bigger and bigger. Nature is a development trend. Specifically, at present, the high-definition movement market is mainly dominated by 1.3 million pixels and 2 million pixels, and the multiple is generally only 20 times. The core components of the movement, lens, sensor, image processing technology, focusing technology, etc., each module restricts the development of the movement. With the development of movement lens and sensor technology, a higher resolution, higher magnification, lower illumination movement is required to meet the higher monitoring needs of users. Furthermore, the intelligent development of image processing technology makes image restoration better, such as the wide dynamic function of the movement. The shortcoming is that it needs to be manually turned on for wide dynamic scenes and adjust the intensity, while the intelligent application can do it. Automatically identify wide dynamic scenes and adjust image parameters to achieve fully automatic intelligent processing, saving time and cost, and focusing faster and faster.
HD has two trends, one is digital HD and the other is network HD. The main difference lies in the way data is transmitted. Higher definition means higher data traffic and higher requirements for data transmission. Therefore, the development of high-definition all-in-one movements also depends on the development of back-end transmission technology.
