Reducing Security Concerns and Vulnerabilities with Tips from Hikvision to Protect your Home Network


Cybercriminals are growing in sophistication and businesses face new challenges and security concerns. Security Sales & Integrations (SSI) provides guidance on several ways to enhance security in the story, “7 Cybersecurity Essentials to Help Protect Your Business in 2021.”

From the article: “Anyone who follows the news or social media knows how scary the cybersecurity landscape is nowadays. The madness of 2020 and the “instant” Work-From-Anywhere lifestyle has only made this issue worse as our home machines are rarely as secure as those at work. With all of this bad news out there, what is the good news? For the most part, it is that getting back to IT security basics covers most of these [security] concerns.”

Here are several essential ways you can improve security, according to the SSI article:

  • Create good passwords: There are many approaches to creating complex, hard-to-hack passwords, but the article’s author recommends creating passwords that have 8 or more characters. “Complex passwords have upper and lower case, numbers, and punctuation marks too. Passphrases are even more secure. You can also create passwords from passphrases: NowistheTimeforStrongPassWords@2021 becomes ‘NitTfSPW@21.’”
  • Enable MFA wherever possible: Multi-factor authentication (MFA) requires a user to provide an additional means of authentication or verification, in addition to entering a username and password, to log into an account or website. This makes it more difficult for threat actors to hack your accounts.
  • Update software with patches: All software programs require updating from time to time. Computers, mobile devices and even home routers need to be updated with patches when they become available.

Hikvision covered ways to reduce security concerns and address vulnerabilities in this blog: “Part 2, Hikvision Senior Director of Cybersecurity on Protecting Your Home Network from Vulnerabilities.” The article includes tips to enhance security for your home router.

IMPORTANT! This model requires non-standard firmware. Do Not Install standard firmware (e.g. v.4.1.xx) on this model. Doing so will permanently damage your system. You must use custom firmware v.4.1.25 from the iDS-9632NXI-I8/16S product page.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.


Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.


After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.


Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.


Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.


Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.



Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.
