硬盘是高度复杂尖端的装置,它结合了电磁、机械和电子方面的技术,以非常高的密度存储信息。硬盘技术使个人电脑、电影点播、数字录影机和数字音乐点唱机的开发成为可能。作为视频监控系统中的后端处理设备,DVR在整个安防系统中发挥着非常重要的作用,而硬盘又是DVR的核心组成部分。对于视频监控系统而言,它需要的是能在高负荷条件下保持高稳定性能的硬盘。
Hard drives are highly sophisticated devices that combine electromagnetic, mechanical and electrical technologies to store information at a very high density. Hard disk technology makes the development of PCs, movies on demand, digital video recorders and digital music jukeboxes possible. As a back-end processing device in video surveillance systems, DVR plays a very important role in the entire security system, which is also a core part of DVR. For video surveillance systems, what it needs is a hard drive that can maintain high stability under heavy load conditions.
