Many people have doubts, saying that the hard disk in the monitoring system uses a dedicated monitoring hard disk, but also the ordinary computer hard disk. What is the difference between the two? Is the effect different?
Under normal circumstances, unless the customer requests, the engineering company will install the ordinary computer hard disk on the hard disk recorder. If you want to say something different, it is actually the difference between the comprehensive performance of stability and reliability.
In fact, about 50% of the causes of DVR failures are from the hard disk read and write failures. According to professional tests, the use of monitoring dedicated hard disks reduces the read and write failures to less than 6%. That is to say, the use of ordinary computer hard drives will greatly increase the failure rate, increase the cost of maintenance services, and also have a loss of its own brand image.
So how do you distinguish between a dedicated hard disk and a normal computer hard disk? what differences are there?
The monitoring dedicated hard disk is customized according to the system characteristics of the digital hard disk recorder. It can support the recording and playback of the recorder very smoothly, optimizes the storage and reading and writing of the streaming media, and is more stable than the ordinary computer hard disk in terms of system data and mathematical image information.
The power-on start mechanism of the ordinary hard disk is instantaneous full-speed start, and the current will reach about 2 amps or even higher. The monitoring dedicated hard disk startup is slowly accelerated, and the current will be controlled at about 1.5 amps. If a VCR is installed with multiple hard disks, this will inevitably cause damage to the power supply.
In addition, the monitoring dedicated hard disk is optimized on the read and write structure to extend the life of the head.
The monitoring dedicated hard disk is designed and developed to install 24×7 enterprise-level environment requirements, which is 24 hours a day and 7 days a week. The general computer hard disk design is designed with 8×5 environment requirements, which means 8 hours of work per day and 5 days of work per week. All ordinary computer hard disks are not suitable for long-term continuous reading and writing. If forced to use, it will damage the hard disk, and the hard disk will be abnormally sounded, read and write faults, work stop, video data loss and other problems.
Therefore, all engineering companies, especially in large-scale monitoring systems, still try to use monitoring dedicated hard drives. Because monitoring dedicated hard drives has an average trouble-free running time that is much longer than a normal computer hard drive, stability and reliability are higher.
