How to upgrade the NVR system?

by ChenJanice 25 Apr 2023 9 Comments

Firmware updates are crucial for the proper functioning, security, and performance of an NVR system. They provide bug fixes, feature enhancements, and often address known vulnerabilities. Here are some important points to consider regarding firmware updates for an NVR system:

  1. Regularly check for updates: Manufacturers periodically release firmware updates for their NVR models. It's essential to visit the manufacturer's website or check their support portal regularly to see if there are any available updates for your specific NVR model.

  2. Backup your data: Before performing any firmware update, it's critical to back up all data and configurations on your NVR system. This ensures that in case anything goes wrong during the update process, you can restore the system to its previous state.

  3. Read the release notes: Always read the release notes or changelog provided with the firmware update. This document will detail what changes, fixes, and improvements are included in the update. It will also often contain instructions on how to apply the update.

  4. Follow update instructions: Manufacturers usually provide specific instructions on how to update the firmware for their NVR models. These instructions might involve using a web interface, USB drive, or a dedicated update tool. Follow the provided steps carefully to avoid any issues.

  5. Stability vs. cutting-edge: Some firmware updates may introduce new features but could still be considered beta versions. If your NVR system is in a production environment, it may be wiser to wait for a stable release rather than rushing to get the latest features.

  6. Security patches: Security vulnerabilities may be discovered in NVR systems over time. Manufacturers often release firmware updates to address these vulnerabilities. It's crucial to promptly install these updates to protect your system from potential threats.

  7. Update all relevant components: Some NVR systems have separate firmware updates for various components like cameras, switches, or additional modules. Ensure that you update all relevant components to keep the entire system up to date.

  8. Test after the update: After applying the firmware update, thoroughly test the NVR system to ensure that all cameras are functioning correctly, recordings are being made, and any new features or improvements are working as expected.

  9. Keep a record: Maintain a log of all firmware updates applied to your NVR system, including the date, version, and any issues encountered. This log can be valuable for troubleshooting purposes and for keeping track of the system's maintenance history.

  10. Professional assistance: If you are uncertain about how to perform a firmware update or encounter any difficulties during the process, consider seeking assistance from the manufacturer's support team or a professional with experience in NVR systems.

By keeping your NVR system's firmware up to date, you ensure that it remains secure, stable, and capable of delivering optimal performance for your surveillance needs.

Guys please don’t buy their product. Don’t expect any support from their team. Go for HIKVISION. I had to change my NVR to HIKVISION as they are not supporting.

I would like to upgrade the system and they are fine if you send the FW for my system. Tried resetting the NVR but it didn’t help.

i have recorder NVR K8208-3WS, SW version: Do you have any software update, because I tried to update online, but the recorder downloads something→ resets but→ installs something but nothing happens. It’s the same version after all. I am currently trying to add a camera to the recorder that was described as your company’s model: XM-PT817-50W.
