Hikvision Senior Cybersecurity Director on Addressing Work From Home Concerns & Vulnerabilities


Security challenges have increased with the pandemic as threat actors take advantage of remote workers and coronavirus concerns by ramping up cyberattacks such as phishing. The rapid transition to work-from-home and other impacts have highlighted cyber vulnerabilities. In the Canadian Security magazine story, “Five cybersecurity lessons from 2020: COVID-19 has brought some cybersecurity challenges into sharper focus,” the author covers key security lessons and vulnerabilities the pandemic brought to light.

“We’ve seen two years’ worth of digital transformation in two months. From remote teamwork and learning, to sales and customer service, to critical cloud infrastructure and security,” said Satya Nadella, Microsoft CEO, in the article.

Some of the 2020 cybersecurity lessons covered in the story include:

  • The definition of resilience has changed since the pandemic. Referencing London’s St. Bartholomew’s Hospital—which survived many crises including two world wars—cancelled more than 2,500 patient appointments in 2017 when WannaCry ransomware hit. While organizations may be facing new or heightened vulnerabilities with digital transformation and work-from-home cyber threats, it’s still quite a feat that we were able to shift to online learning and remote work very quickly. This rapid change would have been nearly impossible twenty years ago, according to the article.
  • Multi-factor authentication (MFA) can greatly reduce the success of cyberattacks. MFA adds two or more pieces of verifiable evidence or factors to the authentication process to greatly reduce security concerns by lowering the chances of an account being accessed by the wrong person.
  • Zero Trust network architecture, designed to improve security and reduce risk of breach, is the direction organizations are taking. “Organizations that were successful in making the rapid transition to most employees working remotely had invested in a Zero Trust architecture, including MFA, device management, and conditional access enforcement,” said the article.

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.
