Here we give an example to analyze the important role of monitoring dedicated hard disk in high-definition monitoring system:
First, the life of the hard disk: Storage life is the key to control the cost of the monitoring system, the ordinary hard disk will start at full speed when starting, the instantaneous current may reach 2A. The monitoring hard disk will start slowly and the starting current will be controlled below 2A. Because the monitoring system usually installs more than one hard disk, it will generate a large starting current at the instant of startup. If it is an ordinary hard disk, the power supply will be unbearable and even burned. The theoretical average failure-free running time of monitoring hard disks is much longer than that of ordinary hard disks, and the stability and reliability are even higher.
Second, the difference between continuous working time: ordinary PC hard drive is not suitable for long continuous reading and writing, especially high pressure monitoring system storage pressure, using ordinary PC hard drive for a long time continuous reading and writing will greatly damage the hard disk, so that the hard disk Abnormal sounds, read/write errors, work stoppages and other issues have occurred and the hard disk has eventually been damaged. For years of continuous operation, it is required that the hard disk must be able to work continuously for a long period of time. To meet this requirement is to monitor a dedicated hard disk.
Third, power consumption and heat dissipation: As high-definition monitoring media, the general storage pressure, the average PC hard drive operating power is generally about 14.5 watts, monitoring dedicated hard drive operating power is generally about 8 watts, only equivalent to ordinary PC Hard disk power consumption is 55%. About 75% of the operating power will be converted into heat energy. Using dedicated hard drives for monitoring will not only reduce power consumption but also generate much heat. ----Reduce system cooling requirements and adapt the system to the environment. More powerful.
IV. Transmission and Performance Differences: In addition to the transmission mode of the traditional PC hard disk, the monitoring dedicated hard disk also introduces an updated transmission mode—uninterrupted transmission mode. The maximum transmission mode is 65 MB/s. Through the introduction of uninterrupted transmission mode, the support of the hard disk for streaming media is more reliable, which fully guarantees the fluency and stability of the playback of the digital hard disk recorder while recording, which is a feature not possessed by other hard disks. In addition, high-definition stream optimization is also a unique feature of the monitoring hard disk for high-definition monitoring, which can better enhance the performance and stability.
