Best Practices

Making smart choices about cybersecurity will help you more effectively protect the valuable assets you are already guarding with physical security. Here are ten tips to help guard against a potential cyber attack.

  1. Keep appliances current: update software and firmware regularly. As vendors find issues, manufacturers work to create fixes that will help prevent issues later. Your due diligence is required.
  2. Passwords as a minimum should be at least 8 characters long and be a combination of letters, numbers, and special characters. Everyone should be assigned their own username and password. This ensures accountability
  3. Each user account should only be given the authority to access the resources required to fulfill their specific responsibilities.
  4.  Every transaction that occurs on the appliance should be logged so that there is a record kept for forensics later. This accounting is a must.
  5. Whenever possible, use a firewall appliance between your IT assets and the Internet. At the very least use NAT at your Internet gateway.
  6. Use uncommon ports: “security through obscurity.” This creates an additional step when someone is trying to access your appliances.
  7. When possible, put your network and IT assets behind locked doors to limit unnecessary access.
  8.  Make sure you are using password lock-out features for invalid login attempts and if possible, receive notifications of these attempts.
  9. Design a plan of who to notify in the instance of your appliances being compromised (or simply if you suspect that they have).
  10. If you suspect a vulnerability is due to a flaw with the manufacturer, notify the manufacturer so that they can test. If an issue is found they can also work to fix it.

 

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

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.
