Energy saving has a significant cumulative effect. As far as the security industry is concerned, due to the small scale of the previous market, the demand for energy conservation and energy saving effects are not obvious, but with the continuous expansion of the security market, the advantages of energy-saving products are becoming increasingly prominent.
According to Wang Xiaohu, chief business executive of WD Shenzhen Representative Office, with the rise of large-scale projects, the application of electronic surveillance systems has become increasingly popular, resulting in more and more back-end storage and higher demand for energy consumption. At this time, the difference between the energy-saving and cost-effective use of energy-saving products and general products is very obvious.
It is understood that Western Digital's green monitoring and control hard disk (GreenPowerAV) has obvious advantages in vibration damping. WD's GreenPower energy-saving technology enables the hard drive to reduce heat, noise and vibration during working hours, making the operation reliable without affecting performance.
As the hard disk capacity increases, the required power for the hard disk also increases. At present, the power consumption of the current 1TB hard disk is usually higher than 13.5 watts. WD has designed a 3.5-inch hard drive with energy saving as the main attribute. Western Digital's introduction of green hard drives compared to standard desktop hard drives on average saves 4 to 5 W of power while maintaining stable performance.
If a power-saving hard disk can reduce power consumption by 4W, it can save about 10 yuan in electricity a year, and a system with 5,000 hard disks (small centralized back-office storage scale in China) can save a very considerable amount of money in a year. At the same time, too much heat will bring problems such as cooling of air conditioners and thickening of cables. Using energy-saving products can also reduce these hidden costs.
Hard disk is an important aspect of the stable and reliable DVR. Although hard disk technology for DVR applications is already available on the market, hard disk hibernation technology is still a very important technology in DVRs. It is relatively easy to do in the embedded DVR, because the embedded DVR is the embedded system to control the hard disk to run, as long as the operating system can provide such an interface to complete the hard disk dormancy. However, on the PC, the entire hard disk system is managed by Windows. The system does not provide peripheral management of hard disks. Windows itself has a hard disk hibernation system. However, this system cannot meet the application requirements of DVRs.
Zhang Haifeng, deputy chairman of Hanbang Hi-Tech Co., Ltd., said that in the Windows hard disk management system, Hanbang Gaoke has done a lot of research and development work, successfully broke through the limitations of Windows management, can fully realize the artificial control of the hard drive dormancy, the significance of this technology is Greatly improved the life of PC-type hard disk recorders, improved system reliability and reduced operating and maintenance costs. And can support embedded DVR and PC DVR hard drive sleep. The power consumption of a hard disk is about 15W. In addition to the improvement of reliability, the application of hard disk hibernation technology is also very energy-saving.
It is understood that 2 to 4 hard disks are usually installed in the DVR, and 8 hard disks are usually installed for long-term storage environments. After the hard disk hibernation technology is used, only one hard disk is powered on. All other hard disks are hibernated. When the hard disk needs to be replaced, the specified hard disk is woken up. The hard disk that does not need to work can be put to sleep to achieve power saving.
