Part 2: Identifying Your Current Firmware Version

Rule #1 of firmware updates: Never update without knowing what you have now.

Follow these steps to check your current firmware: Support for up to 8 IP cameras Recording

  1. Login to the NVR via a monitor connected directly to the HDMI/VGA port, or via web browser (default IP: 192.168.1.108).
  2. Navigate to Main Menu > Settings > System > System Info > Version.
  3. Look for three critical fields:
    • System Version: (e.g., V4.000.0000000.0.R.210707)
    • Build Date: (e.g., 2021-07-07)
    • Web Version: (Indicates compatibility with browser plugins)

Pro Tip: Write down the entire string. If your search for "dhi-nvr4108h-8p firmware" leads you to a file with a build date older than your current one, do not install it.

1. Security Vulnerabilities

In 2021, a critical backdoor (CVE-2021-33044) was discovered in older Dahua firmware. Attackers could remotely log in with a specially crafted cookie. The dhi-nvr4108h-8p firmware released after 2022 patches this.

Step 1: Identifying Your Current DHI-NVR4108H-8P Firmware Version

You cannot update what you do not understand. Installing the wrong firmware version can brick your NVR. Follow these steps precisely:

  1. Access the NVR Interface: Connect a monitor to the VGA/HDMI port on the NVR, or log in via a web browser by entering the NVR’s IP address (e.g., 192.168.1.108).
  2. Log in as Administrator: Use your admin credentials (default is often admin / admin or admin / no password, though you should have changed this).
  3. Navigate to System Info: Right-click to open the menu, go to Main Menu > System > System Info.
  4. Locate the Version String: Look for a field labeled System Version, Firmware Version, or Software Version.

A typical version string might look like: V4.002.0000000.0.R.220630. Let’s decode that:

  • V4.002 = Major release version.
  • 220630 = The build date (June 30, 2022). This is the most critical part for determining age.

Important Distinction: Do not confuse the Web Interface version (shown in your browser) with the System Firmware version. You need the system firmware version.
