Firmware __exclusive__: Ds-7104ni-sn P

Understanding the Model and Firmware

• Model Number: "ds-7104ni-sn p" seems to be a model number, likely from a specific manufacturer's product line, possibly related to surveillance or networking equipment given the format.
• Firmware: Firmware is the software that is embedded in a hardware device. It controls the device's operations and provides low-level control over the device's hardware.

Problem 2: NVR Stuck at “Upgrading, Do Not Power Off” ( >30 minutes)

Cause: Corrupt firmware file or USB drive failure. Solution:

• Perform a power cycle (unplug for 10 seconds, plug back in). If it boots to old firmware, try a different USB drive (FAT32, <16GB).
• If it remains bricked, you may need to use TFTP recovery (advanced – see below).

Issue D: PoE Ports Not Detecting Cameras

Fix: After update, the internal PoE switch VLAN may reset.

• Go to Network > PoE Configuration.
• Set the camera IP range to 192.168.254.x (default).
• Or manually add cameras via the “Custom Add” button.

Problem 3: Cameras Go Offline After Update

Cause: Update reset the ONVIF port or encryption settings. Solution:

• Go to Camera Management → Custom Protocol → Reset ONVIF ports to 80/8000.
• Re-enter camera passwords if using Hikvision’s “Enable Stream Encryption”.

7. If something goes wrong – recovery

You’ll need:

• TFTP server (e.g., TFTP64)
• Correct digicap.dav
• Direct Ethernet cable between PC and NVR

Process:

1. Set PC IP to 192.0.0.128
2. Run TFTP server, point to file directory
3. Power cycle NVR – it will pull the file automatically
4. Wait 10 min, then restore defaults.

Safe Sources:

1. Hikvision Global Portal (hikvision.com):

   • Go to Support > Tools > Firmware.
   • Search for DS-7104NI-SN/P.
   • Note: The global site often removes old models. You may find only the final release.

2. Hikvision Regional Distributors (USA, EU, Asia):

   • US: Hikvision USA (requires login for some files).
   • EU: Hikvision Europe’s download center.
   • Pro tip: If the global site shows “No results,” try DS-7100NI-SN series (general firmware often works).

3. Official Technical Support:

   • Create a ticket. Provide the serial number (S/N) on the bottom sticker. They will email you the correct .dav file.

Why Users Search for This Specific Firmware

The search for "ds-7104ni-sn p firmware" is typically driven by three distinct needs:

1. Bug Fixes and Stability: Early revisions of NVR firmware often contain bugs—such as unexpected reboots, loss of camera discovery, or email notification failures. Manufacturers release updates to patch these issues.
2. Security Patches: In the post-Mirai botnet era, surveillance devices are notorious targets for cybercriminals. Hikvision regularly releases firmware to close backdoors, harden SSL/TLS encryption, and disable default credentials. Searching for firmware is, therefore, a cybersecurity measure.
3. Feature Enhancements: A firmware update might unlock ONVIF compliance for third-party cameras, improve the streaming efficiency of the Hik-Connect mobile app, or add edge storage recording formats.

Part 2: Identifying Your Current Firmware Version

Before updating, you must know your baseline. Here’s how:

1. Via Local GUI (Monitor/Mouse):

   • Right-click on the live view.
   • Go to Main Menu → System Configuration → System Settings → System Information.
   • Look for Firmware Version (e.g., V4.30.010 build 210625).
   • Also note the Hardware Version (e.g., V1.0). This is critical because the same model may have different hardware revisions requiring different firmware.

2. Via Web Browser (Remote Access):

   • Log into the NVR’s IP address using Internet Explorer (or Edge in IE mode – Hikvision still requires legacy browser support for many features).
   • Navigate to Configuration → System → System Settings → Basic Information.

3. Via SADP (Hikvision’s Search Tool):

   • Download SADP from Hikvision’s website.
   • Run it on a PC in the same LAN.
   • Find your NVR by serial number. The firmware version is displayed in the table.

Write down these values. Mismatched firmware (e.g., using a DS-7104NI-SN firmware on a DS-7104NI-SN/P) can brick your device.

Part 7: Security Implications – Why You Must Update

In 2021, Hikvision disclosed several critical vulnerabilities (CVE-2021-36260, CVE-2021-36261) that affected many NVRs including the DS-7104NI-SN/P. Attackers could remotely execute code, disable recording, or add the device to a botnet.

Firmware versions older than V4.30.000 are at high risk.

• Fixed in V4.30.010+ – Disabled backdoor accounts, enforced HTTPS, added password complexity rules.
• Recommendation: Even if your system is air-gapped, update for stability. A power surge or HDD failure can corrupt older firmware’s file system.
