In 2010, the industry was dubbed "HD Year One" due to the launch of a large number of high-definition network products; only one year later, the industry has undergone earth-shaking changes. With the advancement of technology, the integration of other industries, the network HD is no longer The only master of high-definition security, such as 960H <960 (H) × 576 (V)> analog HD and HD-SDI digital high-fiercely born, want to network with high-definition three world.
Analog is covered by digital This year's analog cameras have almost been overshadowed by digital products, but the 960H analog high-definition products are blooming everywhere, which in turn allows us to see that the analog products still have a lot of room for improvement. The 960H quasi-HD solution was jointly defined and developed by Techwell and Sony under the Intersil umbrella. The analog camera uses Sony's new generation 1/3", 1/4" wide dynamic, low illumination 960H CCD Sensor and Effio ISP solutions, DVR. The end uses Interwell's Techwell's newly released TW9960 analog quasi-HD A/D solution. The new 960H standard is not only fully compatible with traditional SD video standards, but also can increase the image resolution by more than 30%, making the video image preview up to 650 lines, video playback up to 540 lines, regardless of preview or playback image quality is higher than The quality of the traditional D1 image (preview 540 line, playback 480 lines), while meeting the real-time, further meets the user's requirements for higher image quality.
At the same time, since the resolution of the 960H is 960×576, which is exactly 1/4 of 1080P, the user can also smoothly transition to the 1080P system. The 960H's camera can also be used with traditional DVR equipment; the DVR with the TW9960 solution is also compatible with traditional D1 analog cameras.
Before the advent of high-definition project reconstruction project 960H, many contractors wanted HD projects. It was not only the front-end cameras but also lines and storage devices that could be replaced with network HD solutions. This brought great difficulties to the project transformation; 960H Breaking the status quo that simulation can not achieve high-definition monitoring, it only needs to replace the front-end camera, the original remaining equipment does not need to be replaced, the construction is convenient, and it is greatly favored by the engineering companies. 960H products also have a major feature, that is, it inherits the advantages of analog products, image transmission without delay, the image quality because there is no codec, image reproduction realistic.
At last year's security exhibition, SDI model products took shape. The only manufacturers exhibited were Tiandi Albertson, Huiyou and Skyworth. At last year's security exhibition, SDI was no longer eye-catching. Instead, it was high-definition. SDI product - HD-SDI. Not only the front camera, in the signal transmission link, Youtepu has taken the lead in the introduction of optical fiber, twisted pair, and coaxial line transmission solutions for SD-SDI, HD-SDI, and 3G-SDI, forming optical fiber transmitters. , Multiplexers and signal converters that convert SDI and MDMI signals to each other, such as a complete product portfolio. At the same time, UTP's SDI fiber optic transmitter not only extends the transmission distance to 20 kilometers, but also embeds RS485 control signals, which is particularly suitable for security surveillance SDI dome camera applications, so that SD technology and security have been more in-depth integration. According to rough statistics, more than 80 manufacturers of SDI-related products were produced and manufactured this year. Products include cameras, optical transceivers, storage devices, and displays. From a few of last year to more than 80 this year, they are dozens of times. The annual growth rate also makes us unexpected. SDI technology has its obvious advantages. Although it is a digital signal, it is compressed without coding and decoding, and the image is displayed directly on the wall. The data is transmitted without loss, the sharpness of the picture quality is high, the transmission is not delayed, and full HD rendering can be achieved. It is also more flexible and can be completed with existing coaxial cables. Construction simplicity and excellent monitoring results make it the first choice for demanding monitoring solutions.
The introduction of digital technology into security Digital broadcasting technology has been showing strong growth momentum since it was introduced into the security industry. Although due to its expensive cost and storage bottleneck, it once caused many people in the industry to disregard its development prospects, but only pay attention to it. Real-time monitoring, such as the application of military drills, using high-definition signal sources directly on the wall, compressed storage, its disadvantages will be ignored, this is the main SDI storage solution used by manufacturers at this year's show.
From the perspective of this year's show, manufacturers are focusing on HD-SDI products and very few SD-SDI cameras. In response to high-definition demand, some manufacturers have introduced 3G-SDI products that support higher-resolution image quality such as 1080P and digital cinema, further promoting the growth of the SDI family. Especially worth mentioning is that JVC has also introduced a concept-level 4K-SDI camera with a resolution of 3840×2160. Its ultra-high definition makes the image extremely delicate and clear, which can be suitable for TV broadcast applications. According to the manager of JVC Han Xiaozhou, the highest number of SDI cameras currently appearing is 7K-SDI, showing rapid and advanced technology development.
Digitalization into the future trend Most people in the industry believe that network is the development trend of the times, security must keep up with the times, and network digitization is imperative. Existing defects are there, but the solution needs a breakthrough process; some manufacturers believe that simulation Security is still the mainstay, and the emergence of analog high-definition is a very good response to the network; while SDI technology can avoid the network delay and data loss problems and can achieve digital applications, therefore, the development of SDI is also unstoppable. Network high-definition, analog high-definition, digital high-definition at the same time, indicating that the three high-definition technologies have their own advantages and disadvantages, their respective advantages can not have both, their respective disadvantages but make up for each other, a single technology can not completely solve the existing problems in the short term, in the absence Under the circumstances of who is superior or inferior, there are three kinds of high-definition technologies coexisting.
