Hikvision Cybersecurity Director Discusses Password Management Strategies, Using Password Managers to Reduce Security Concerns

In our recent blog, Hikvision discussed the challenge of creating complex passwords and provided three rules for creating good ones to reduce security concerns and hacking risks.

In that blog, we talked about how we all hate passwords and how the cybersecurity wonks tell us that we have to do unreasonable things like:

  • Make passwords so complex that we can’t possibly remember them (long and multiple character sets)
  • Make a unique password for every one of the tens or hundreds of sites and applications that we use. Oh, and they all have to be long and strong which means we won’t remember them.

Today we are going to explore how you can achieve this and actually make your digital life more secure and much easier than when you had to remember all of those passwords or look them up on a spreadsheet on your computer’s desktop. Welcome the Password Manager!

First, we’ll look at an overview of common password management strategies below, then discuss password managers as a tool in more detail.


Common Password Management Strategies

Below are some of the common password management strategies that people use today:

  • Reusing simple passwords (i.e. monkey123), which is high risk because it is easy to guess (by guessing, I mean using a super-fast password cracking/guessing tool).
  • Reusing complex passwords (i.e. My dog likes to eat at 8 a.m.). This is high risk because while the password is good, if anyone guesses or learns it, they can use it on other sites as well. For example, if your LinkedIn password is discovered, the bad guys/gals will try that username and password on every social media and popular website to see if you used it elsewhere.
  • Saving unique passwords in an unencrypted document or spreadsheet on your computer. While you are protected against someone getting access to your passwords document unless they are logged into your computer, if someone does get access to your files or malware gives access to an attacker, then it is game over.
  • Creating unique but predictable complex passwords for each account (i.e. Facebook**pw4224). These are good passwords, but expect that if someone gets one of your passwords, they can likely figure out the rest of your passwords.
  • Writing all of your passwords in a book and keeping it locked up. If the book is properly secured, then this might be low risk. Locked in a desk at your house is much better than locked in a desk at work. However, if there is a fire or flood, you would lose all of your passwords.
  • Using a password manager with unique, complex passwords for every site. This is low risk. The risk here is if you forget your master password or if someone else gets your master password. More details about password manager tools below.


The Password Manager: A Tool to Reduce Password Security Concerns

A Password Manager is a software tool that is used to store all of your passwords in an encrypted file so that you, and no one else, have very easy access to them, helping to minimize security concerns. Most modern password managers have additional features such as cloud storage, auto-filling fields, and password generators that make very good passwords.

The cloud storage feature of password managers provides easy access to your passwords from different devices. While it sounds scary to have all of your passwords stored online, a good password manager will encrypt all of your password data before it is uploaded to the cloud and will make sure that only you have the keys (the master password that you set) to decrypt your passwords on each device. All of this security is great unless you forget your master password. In that case, you would lose everything.

The autofill feature is convenient because when you go to a site, such as LinkedIn, the password manager’s browser plugin recognizes the URL and sees the username and password fields then enters your username and password automatically. This is not only convenient, but it also helps defend against keystroke login malware, that could learn and share your passwords. It also ensures that your username and password are not entered into a doppelgänger domain website, like rather than This feature has however been abused and used for some creative attacks. By hiding the username/password fields on a web page that are not viewable by the person visiting that page, some attackers have been able to harvest account credentials. This Wired article goes into greater detail about this type of attack.

The password generator is a very important part of this whole solution. The password manager can’t help you much if you create simple passwords such as 12345678 or monkey123. So, the password manager will recommend passwords for you and if you accept them when creating an account, it will automatically store that in your password manager. For example, here is a screenshot from the password generator in LastPass. You can see that it is 24 characters and is using all four-character sets (uppercase, lowercase, numbers, and special characters) to create a difficult password to guess and a nearly impossible password to remember. Good thing you don’t need to remember this password!

There is certainly debate over the problems with password managers: What if you forget your master password, or what if someone gets your master password and uses it to hack your account? These are valid questions, however, with the rapid growth of account compromises and data security breaches, the risk seems far greater for someone is using simple passwords and trying to remember them or reusing those passwords on multiple accounts.


The Password Manager: A Tool to Reduce Password Security Concerns


Here are a few articles that compare and contrast the leading password managers.

In closing, I’ll say that password managers will greatly help to secure your accounts, but are they enough? In the next blog post about passwords, I’ll explain Multi-Factor Authentication (MFA), and how and why you should use it almost everywhere you can.

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.

K-Series DVR upgrade instruction
The Turbo 4 Hybrid DVR K series has multiple models and across different platform and chipset. It also has similar firmware development of other recording product line; DVR K series has also introduced the GUI4.0 to ensure the series to be compatible to the newest technology available. The new database architecture is also brought into the DVR firmware v4.0 to be future proof and for better recording search experience. 

Database Optimization and Repair

As more affordable cameras 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 optimize. If you are experiencing issues, where playback is expected but not found, please make sure to perform "Database Rebuild" as indicated in the procedures and scenarios below.

Preparing the Upgrade

Before proceeding with upgrade, it is recommend exporting DVR configuration file from the DVR over the network or on to a local USB drive.


Action after firmware upgraded 

1. Upgrade the DVR according to the chart above. 

2. Reconfirming Channel's Recording Schedule 

    - Confirm channel's recording schedule is enable. 

    - Check if the channel is on correct recording schedule.

3. Double Check Storage Setting

    - Make sure all channel are assigned to record on its HDD group when the Storage setting is under Group Mode. 

4. Perform Database Rebuild locally. 

    • Some version above support Database Rebuild via web access - K51 and K72

    • Perform Database Rebuild regardless if system is having any database issue symptom. 

    • Database Rebuild process is average ~30 to 60min per TB. The process may still varies depends recording data.

    • After Database Rebuild - Check log to confirm Database Rebuild has went thru properly. 

    • If Database Rebuild Started and Stopped log has been log only within few minutes. Database rebuild may not has been completed properly. It is strongly recommend performing the Database Rebuild again.

    • To check log > System > Log > Information > Database Rebuild Started and Stopped.

    • If the log option is not available - access system via SSH can also obtain similar result.

5. Recording Data is still missing after database rebuild process. 

If the data has not been recorded or has been overwritten, Database rebuild process is not able retrieve those lost data. Have the system upgraded to the latest available firmware version above to prevent any future data lost is strongly recommended for all application.





In light of the global semiconductor shortage, Hikvision has made some hardware changes to the DS-76xxNI-Q1(2)/P NVRs, also known as “Q series.”


These changes do not have any effect on the performance, specifications, or the user interface of the NVRs. For the ease of reference, these modified units are known as “C-Version” units. This is clearly indicated on the NVR label and on the box by the serial number.


The only difference between the “C-Version” and “non-C-Version” is the firmware. The firmware is not interchangeable:


  • The C-Version NVRs must use firmware version v4.31.102 or higher.
  • The non-C-Version (Q series) NVRs must use firmware version v4.30.085 or older.


Please do not be alarmed if a “Firmware Mismatch” message pops up on the screen during the firmware upgrade. This simply means that the firmware does not match the NVR’s hardware. Simply download the correct firmware and the upgrade will go through without any issue.
