In video surveillance storage products, there are differences between sub-divided hard drives and ordinary hard drives. In the security video surveillance project, the storage of surveillance videos requires the use of hard disks. However, ordinary hard disks do not support long-term read/write operations of 7*24 hours. After a certain period of time, they are prone to problems. Therefore, in video surveillance projects, it is recommended that Monitoring level hard disk. The IP-SAN, network storage and other devices used in large-scale video surveillance projects are also recommended to use more stable enterprise-class hard disks. What is the difference between the monitor-class hard disks, enterprise-class hard disks and ordinary hard disks? operating hours In the design process, the monitor-level hard disk must meet the monitoring equipment 7*24 hours video storage, while the ordinary hard disk design is 5*8 hours, which means that one week use five days, one day use eight hours. However, if an ordinary hard disk is used on a monitoring device, it will take a long time to read and write, which will inevitably affect the service life of the hard disk. Instant start voltage The momentary starting voltage of the ordinary hard disk is generally more than 2V, or even higher, while the monitoring level hard disk is slowly started, and the voltage is controlled below 2V to prevent the hard disk from being damaged due to the high instantaneous voltage. Instant start current The instantaneous starting current of the ordinary hard disk is between 2.8A-3.2A, while the control current of the monitoring hard disk is below 2A. Because the monitoring equipment saves the monitoring video for a long enough time, the number of hard disk installations is large, and the instantaneous startup current and voltage are small, which greatly reduces the startup power consumption of the hard disk and increases the service life of the hard disk. Operating power The operating power of ordinary hard drives is about 14 watts, while that of monitor-class hard drives is about 8 watts. Cooling Because the operating power consumption of the monitor-class hard disk is lower than that of the ordinary hard disk, most of the operating power is converted into heat energy, and the heat dissipation of the monitor-class hard disk is better than that of the ordinary hard disk. Shock resistance Because the monitoring equipment installation environment is relatively complex, such as on-board monitoring, the anti-vibration requirements for hard disks are relatively high, so the monitoring-level hard disks fully consider the anti-seismic conditions during the design process, and ordinary hard disks have poor anti-seismic performance and are easily bumped or beaten. damage. reliability Because the monitor-level hard disk is mainly used for storage of video surveillance video, the security and reliability requirements of the monitor-level hard disk are relatively high, and important video files are prevented from being lost due to the damage of the hard disk. The safety and reliability of ordinary hard disks are also high, but they are slightly worse than that of monitor-level hard disks.
