Three HD leading double security monitoring stores

After the double festival, security monitoring stores are still surrounded by high-definition atmosphere, from IP network high-definition, analog high-line high-definition to HD-SDI cross-border HD. For the three high-definition monitoring products, the current high-definition monitoring equipment in the store is still based on analog monitoring, ranging from 540 lines to 700 lines, of course, there are businesses to launch 800 lines and even 1000 lines, anyway, I did not hear the "so high-definition" The simulation equipment, whether or not there are tricks we still need to determine.

Civil HD: 700-line analog HD is supplemented by high-definition IP. We divide the surveillance market into two major parts, one is a small-scale surveillance system based on the civil security market, which includes homes, chain shops, communities, and schools. Currently, in these areas, analog high-definition monitoring equipment occupies more than 70% of the market. Of course, in addition to analog high-definition equipment, home-based single-point IP surveillance cameras and IP networks used on campus monitors intelligent networked alarms. There are also many devices. But overall, in the civil security market, analog HD is still the mainstream in the next three years.

Industry HD: IP network is mainly HD-SDI supplemented with the civil security market. The industry-wide monitoring market is dominated by high-definition IP networks. Up-and-coming HD-SDI HD equipment is an auxiliary project. Of course, according to insiders, in the safe urban road monitoring project, the multi-point camera equipment is also not all high definition. When considering the project cost, select some IP standard equipment.

In addition to IP surveillance cameras, some high-end industrial applications have selected HD-SDI HD surveillance cameras. Taking the financial sector as an example, HD-SDI devices can provide images with a network delay of less than 100ms, and the images are non-compressed to restore the most real situation in front of them.

Three high-definition monitoring equipment to pursue different believe that many people for the IP network, high-definition, 960H analog HD and HD-SDI digital high-definition some scratching their heads, let us carefully distinguish the difference between these three!

1, network HD pursuit of value-added services For the future development trend of network high-definition monitoring equipment, Matsushita Electric Co., Ltd. Wang Ke mentioned on the Security Forum, in the continuous increase of ultra-high resolution images and value-added information transmission environment, to achieve system operation Stability and operation accuracy. For the processing of value-added information, it is through the direct communication between the device and the device to easily implement back-office operation and management.

2, HD-SDI and network high-definition long-term coexistence is the same, in the face of new products HD-SDI high-definition surveillance cameras, due to the high degree of restoration of images and connection methods, completely follow the analog HD and IP HD, HD-SDI The smooth upgrade of the original analog system to a high-definition system is more suitable for project applications requiring high reliability, real-time performance, and simple operation and maintenance requirements.

The comparison of the three mainstream high-definition monitoring equipment for the analog monitoring system, in fact, the clarity of the image is a major obstacle to the development of the device, I have done tests, a 1.3 million-pixel IPC imaging level in the 700 lines, with the current 960H Analog surveillance, in the EffioDSP with the new CCD can also reach the level of 700 lines. At the same time, under this scheme, high-resolution image quality can be provided, the signal-to-noise ratio of surveillance cameras can be improved, and the degree of color reproduction can also be improved.

In addition to front-end devices, of course, we can not ignore the back-end storage devices. Due to the different front-end devices, there are also significant differences in the natural back-end storage devices. IPC corresponds to NVR, HD-SDI corresponds to SDIDVR, and 960H analog HD corresponds to 960HDVR.

It is not difficult to see from the comparison of the two figures above and below that for these three high-definition monitoring devices, there are pros and cons in terms of application, cost control, and post-maintenance. In fact, for the three high-definition surveillance products, currently in the security market in a more obvious separatist battle, their respective areas in the development of smooth sailing, there will always be another high-definition products threaten its status. Perhaps this is the market and there is competition before it can move forward.
