Analyze what impact million HD will have on the security industry

In recent years, with the development of digital video surveillance, the security industry has begun to undergo drastic changes. The security industry began with front-end lenses, cameras, video servers, access control, optical transceivers for intermediate transmission, twisted-pair cables, and back-end hard disk video recorders. Matrix, video wall decoders, heads, alarms, monitors, etc., the longer the product line, the bigger and bigger the industry.

In recent years, the security industry has been increasing at a rate of 25%-30% each year. After the initial stage of profiteering, the security industry has gradually begun to mature in the market. Today, the security industry market concept hype into the "high-definition" speculation period, but also to the security, especially the video surveillance product line has brought a huge impact, let's look at the following from the concept of each product to see what will happen:

1) Lens Million HD Cameras, generally recommended to use more than one million high-definition lens with high-definition performance, the domestic currently in this also need to strive to enhance, and provide a full range of millions of high-definition lens species to adapt to the development of millions of HD .

2) All-in-one in the simulation era, high-end camera movements such as one machine mainly controlled by foreign manufacturers, and domestic manufacturers of high-speed ball are usually imported Sony and other movements, and the arrival of millions of high-definition era, will change this situation At present, there are already a few strong R&D companies in the country that have developed their own one-piece movement that is used to make millions of HD domes. Domestic high-definition integrated machine will gradually replace the imported one.

3) Analog Camera The highest quality of the analog camera does not exceed D1, and the resolution is far inferior to that of a digital high-definition camera. In addition to the great disparity in resolution and resolution, it is also in the aspects of anti-jamming, wiring cost, wiring difficulty, signal to noise ratio, etc. Unlike digital cameras, as the sales volume of digital high-definition cameras increases, the cost and price will become closer and closer to analog cameras, eventually bringing analog cameras out of the stage of history.

4) Ordinary network cameras Traditional common network cameras, although the back-end output is digital compressed video like a digital high-definition camera, but its front end is essentially a CCTV analog camera, followed by a network and video processing module. It has many of the same drawbacks as analog cameras, but it does not have much advantages compared to digital high-definition cameras. Therefore, this kind of transitional network cameras will be more affected and replaced by digital high-definition network cameras.

5) Video Server An ordinary network camera, popular understanding, is equivalent to a single video server + analog camera. However, video servers are usually rarely single-way, or they are completely replaced by ordinary network cameras. Most of the video servers are made into multiple channels. When the types of domestic network cameras are not complete and the quality is not satisfactory, they can be solved using video servers and imported analog cameras.

6) Optical Multiplexer Because digital HD network cameras transmit digital signals instead of CCTV analog signals, long-distance transmission uses optical fiber switches instead of optical fibers. Therefore, in the security monitoring and wiring, the use of optical fibers will become less and less. While fiber switches use more, and fiber switches are also cheaper than optical transceivers.

7) DVR

DVR DVR, whether PC or embedded, its video input is a traditional CCTV analog camera, limited by the quality of the analog camera, while the current video capture chip can only handle the D1 resolution, so the DVR's painting Quality does not go and HD is the eternal pursuit of video surveillance. With millions of high-definition digital cameras replacing analog cameras in large quantities, it is inevitable that DVRs will be replaced by hybrid DVRs, pure digital PDVRs and millions of high-definition NVRs.

8) Monitors In security eras where analog cameras are predominant, monitors use mostly lower resolution traditional CRT monitors. With the application of digital HD, including millions of high-definition walls, these are all ordinary monitors. Can not use, need to use high resolution, such as 1920X1080P, or 1366X768 and so on more than 1 million resolution monitor. Although it is not a technical problem to say such a high-resolution monitor at present, the product category will be more biased towards high-definition LCD monitors in the future.
