[ Huaqiang Security Network News ] In addition to some technical problems, the hard disk recorders are stuck, and many of them are caused by software. Such as: 
1, virus infection virus is a major problem in the operation of hard disk recorders, almost everyone is evil. Viruses can drastically reduce the efficiency of DVRs, causing frequent crashes, data loss, system crashes, and even damage to motherboards, hard drives, CPUs, and more. Therefore, when we find a virus, we need to use anti-virus software such as kv3000, Rising and other excellent anti-virus software to comprehensively check the virus and disinfect the DVR, and upgrade the anti-virus software in time.
2, cmos improper settings This phenomenon is very common, such as hard disk parameter settings, mode settings, improper memory parameter settings, etc., will cause the hard disk recorder can not start. If the memory without the ecc function is set to have the ecc function, this will cause a crash due to a memory error.
3, the initialization file is destroyed Because windows startup needs to read system, ini, win, ini and registry files, if there are config, sys, autoexec, bat files, these two files will also be read. As long as there are error messages in these files, there may be a crash, especially the four files system, ini, win, ini, user, dat, system, and dat are especially important.
4, dynamic link library files (, dll) lost in the Windows operating system, there is a class of files is also very important, this is the extension, dll dynamic link library files, these files are by nature a shared class file, also That is to say, a dll file may have multiple software that needs to be called at runtime. If we delete an application, the anti-installer of the software will record the files it has installed and prepare to delete them one by one. At this time, it is easy to delete the dynamic link library files and also be used by others. In the case of software, if the missing link library file is a more important core link file, then the system will crash or even crash. At this time, we can use tool software such as "Super Rabbit" to delete the useless, dll files, which will avoid accidental deletion.
5, the hard disk has too little free space or too much fragmentation. Because some applications require large memory and hard disk space, if the hard disk has too little free space, when these applications need a lot of memory and there is not much memory on the machine, Virtual memory is needed, and virtual memory is provided by the hard disk, so the hard disk needs to have enough free space to meet the virtual memory requirements. Therefore, when we are equipped with a hard disk recorder, we must configure a larger hard disk. In addition, we must develop a good habit of regularly arranging the hard disk and clearing the junk files in the hard disk. This will not only avoid the crash caused by insufficient free space or debris, but also increase the speed of normal operation.
6, bios upgrade failure Operators should back up bios to prevent accidents, but if the DVR system needs to upgrade the bios, then before upgrading, it is best to determine whether the bios version you use is consistent with your pc. If the bios upgrade is incorrect or there is an unexpected power outage during the upgrade process, the DVR system may not be able to start. So before upgrading bios, you must figure out the bios model. If you are using the bios upgrade tool to back up your current bios, you should copy the previous bios to disk. Also see if the system supports bios recovery and know how to recover.
7. Inappropriate software upgrades Most people may think that software upgrades will not be problematic. In fact, some components shared in the upgrade process will also be upgraded, but when other programs may not support upgraded components, There will be various problems leading to the crash. Therefore, you should pay attention to the operation when upgrading the software. First understand the features, performance and troubleshooting methods of the upgrade software, and then upgrade.
8. Abuse of the beta software There are a lot of operating software on the market for some beta software to check the software's operation and stability, so that it can be properly improved when it is officially published. Therefore, the test software usually has some bugs or In some respects, the software in the beta version is not considered to be fully mature software. Therefore, when we are not very good at DVR, it is best to use the test version of the software to avoid unnecessary errors such as program errors, crashes, or system failures after use. trouble.
9. Illegal Uninstalling Software Because there are so many softwares running on DVRs, people always like to download, install and uninstall software frequently. This is not good. Do not delete the directory where the software is installed directly. If you delete it directly, there will be a lot of garbage in the registry and the windows directory. Over time, the system will become unstable and cause a crash. Therefore, do not download and install software that is not necessarily needed.
10, the use of pirated software is now very pirated software, almost all software has been pirated, because these pirated software may hide the virus, once executed, will automatically modify your system, so that the system crashes during operation. But if you use genuine software, I am afraid it is not realistic, so you can only use pirated software as little as possible, especially if you don't use software and some low-priced software, you don't have to use pirated software.
2, cmos improper settings This phenomenon is very common, such as hard disk parameter settings, mode settings, improper memory parameter settings, etc., will cause the hard disk recorder can not start. If the memory without the ecc function is set to have the ecc function, this will cause a crash due to a memory error.
