Top 10 Reasons Why DVRs Are Dead

In addition to some technical problems, many of the hard disk recorder cards are still caused by software. Such as:

1, virus infection

Viruses are a major cause of hard disk recorders operations and are almost evil for everyone. The virus can make the hard disk recorder work efficiency drop sharply, causing frequent crashes, data loss, system crashes, and even damage to the motherboard, hard disk, cpu and so on. Therefore, we must use anti-virus software such as kv3000, Rising and other excellent anti-virus software to conduct comprehensive virus scanning and anti-virus on the hard disk video recorder when discovering the virus, and timely update the anti-virus software.

2. Improper setting of cmos

This failure phenomenon is very common, such as hard disk parameter settings, mode settings, memory parameter settings, etc., will cause the hard disk recorder can not start. If you set the memory without the ecc function to have the ecc function, it will cause a crash due to a memory error.

3, the initialization file is destroyed

Because windows starts to read system, ini, win, ini and registry files, if there are config, sys, autoexec, bat files, these two files will be read. As long as there are error messages in these files, they may crash, especially the four files of system, ini, win, ini, user, dat, system, and dat are particularly important.

4, the dynamic link library file (.dll) is missing

There is also a class of files in the windows operating system is also very important, this is the dynamic link library file extension, dll, these files belong to the shared class file in nature, that is, a, dll file may be more The software needs to call it at runtime. If we delete an application, the anti-installation program of the software will record the files it once installed and prepare to delete them one by one. At this time, the deleted dynamic link library file will easily appear In the case of software, if the missing link library file is the more important core link file, the system will crash or even crash. At this time, we can use tool software such as "Super Rabbit" to delete unwanted dll files, which will avoid accidental deletion.

5, the hard disk space is too little or too much debris

Since some applications require large memory and hard disk space, if the free space of the hard disk is too small, virtual memory needs to be used when these applications require a large amount of memory and there is not enough memory on the machine, and virtual memory is used. Is provided by the hard disk, so the hard disk should have enough free space to meet the needs of virtual memory. Therefore, when we are equipped with hard disk recorders, we must configure larger hard disks. In addition, we must also develop a good habit of regularly arranging hard disks and clearing junk files on hard disks. This will not only avoid crashes due to insufficient spare space or too much debris in the hard disk, but also increase the speed of normal operations.

6, bios failed to upgrade

The operator should back up the bios in case of an accident, but if the DVR system needs to upgrade the bios, it is better to determine whether the bios version you are using matches your pc before upgrading. If the BIOS upgrade is not correct or an unexpected power failure occurs during the upgrade, the hard disk recorder system may fail to start. So before you upgrade bios, you must figure out the bios model. If you use the bios upgrade tool to back up the current bios, you should copy the previous bios on disk. At the same time see whether the system supports bios recovery and how to recover.

7, improper software upgrade

Most people may think that the software upgrade will not be a problem. In fact, some of the shared components will also be upgraded during the upgrade process. However, when other programs may not support the upgraded components, they will have various problems. Caused a crash. Therefore, when you upgrade the software, you must also pay attention to the operation, first understand the characteristics of the upgraded software, performance, and possible troubleshooting methods and then upgrade.

8, abuse test software

At present, there are many operating software on the market for some beta software to check the feasibility and stability of its software operation, so that it can be properly improved when it is officially published. Therefore, the testing software usually has some bugs or is not stable enough in some respects. No version of the software can be considered fully mature software. Therefore, when we are not very expert on hard disk recorders, it is best to use less software test version, so as to avoid data loss after the use of program errors, crashes, or the system can not start and other failures, to their own unnecessary trouble.

9, illegally uninstall software

Because the hard disk recorders now run a lot of software, people always like to download, install, and uninstall software often, which is not good. Do not delete the directory where the software is installed. If you delete the directory directly, there will be a lot of garbage in the registry and windows directory. As time passes, the system will become unstable and cause crashes. Therefore, do not download and install software that is not necessarily needed.

10. Use pirated software

There are so many pirated softwares nowadays. Almost all softwares are pirated. Because these pirated software may hide viruses, once executed, it will automatically modify your system and cause the system to crash in operation. However, if genuine software is used, I am afraid it is not realistic. Therefore, it is only possible to use as little pirated software as possible. In particular, software that is not commonly used and software that is not expensive are not required to use pirated software.
