Hikvision On Zero Trust as a Method to Mitigate Security Concerns


Hikvision noted in an April 2020 blog that “Barracuda Networks researchers have seen a steady increase in COVID-19 coronavirus-driven phishing attacks, and since the end of February 2020 they found a 667 percent rise in these attacks.” This trend continued throughout 2020. So how can organizations address security concerns related to coronavirus-driven cyberattacks? In the Security magazine article, “Companies need to enhance cybersecurity amid the continuation of COVID-19 in 2021,” the author offers several actions that can be taken to boost cybersecurity in the pandemic’s wake.

From the article: “Cybercriminals love a good crisis. So, it’s no surprise that they jumped at the opportunity to take advantage of the COVID-19 pandemic to exploit tens of millions of home-based workers who have provided new access points to malware, cyber viruses and phishing attacks. The attack surface for attackers has never been wider.”

The article offers several steps organizations can take to mitigate cyber threats:

  • Educating employees is critical. If they are trained to recognize signs of malicious emails or phishing, they will be less likely to click on links that may download malware. Read an overview of phishing by Hikvision’s senior director of cybersecurity here.
  • Organizations with substantial portions of work-from-home staff should balance typical firewall and endpoint protection with an increased investment in “detection and response, managed endpoint and response, and vulnerability management services.”
  • Ensuring that employee devices as well as company software and systems are up to date can boost cybersecurity. The author recommends pushing updates onto operating systems, instead of waiting for users to be notified of a security patch and then take action.

The article also quoted a cybersecurity professional who cited Zero Trust solutions to boost security. Hikvision covered use of Zero Trust as a method to mitigate security concerns in this blog: “Hikvision Senior Director of Cybersecurity on Using Zero Trust Network to Address Security Concerns.”

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.
