Security Concerns and Cybersecurity Trends to Expect in 2021

Reduce Concerns and Risk with Hikvision Recommendations to Boost Your Home Security


Hikvision wrote several blogs about how the pandemic fueled a shift to remote work and an uptick in cyberattacks during 2020. The Security magazine story, “Cybersecurity in 2021—what can we expect?,” covers trends that may impact security concerns and cybersecurity in 2021.

Cybercriminals sought to take advantage of people’s coronavirus fears and the growth in remote workers, leading to a significant increase in phishing, ransomware and other cyberattacks. The article predicts that this trend will continue: “In 2021, we can expect cybercriminals to finetune their attack strategies and adapt to the ‘work-from-home economy,’ pursuing remote workers even more so than in 2020.”

As home remains a workplace, the author of the article expects that cyber attackers will target home machines that can be used to exploit corporate devices. As a result, VPNs may decline as the trusted solution to protect networks. It is also likely that demand will increase for more sophisticated cybersecurity solutions, such as web-filtering (prevents viewers from loading certain websites), intrusion detection, and endpoint protection.

The story’s cybersecurity predictions encompass potential breaches in the healthcare sector and the growth in ransomware attacks and techniques. And phishing attacks on individuals and businesses will continue.

While many continue to work from home, tips to prevent security concerns can be helpful. Hikvision posted a blog about securing your home network with recommendations to boost your home security. Visit the link to read about how to conduct firmware updates and more.

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.
