EZVIZ security cameras are known for their user-friendly interface and reliable cloud features. However, firmware updates—intended to improve security and performance—can sometimes introduce bugs, remove specific features (like RTSP support), or cause connectivity issues with NVRs. When this happens, users often seek to revert to an older version.
Downgrading EZVIZ firmware is a technical process that requires precision. If done incorrectly, you risk "bricking" the device, rendering it unusable. Below is an exhaustive guide on how to navigate this process safely. ⚠️ Important Considerations Before You Begin
Before attempting a downgrade, keep the following risks in mind:
Warranty Voidance: Manual firmware manipulation may void your manufacturer warranty.
Bricking Risk: Cutting power during a flash or using the wrong file will break the camera.
Security Vulnerabilities: Older firmware lacks recent patches against cyber threats.
Auto-Update: EZVIZ cameras are designed to auto-update. You must disable this in the app immediately after a successful downgrade. 🛠 Prerequisites for Downgrading
You cannot downgrade directly through the EZVIZ mobile app. You will need: A Windows PC: Most EZVIZ tools are Windows-based.
Ethernet Connection: Stability is vital; never flash firmware over Wi-Fi.
The Correct Firmware File: This is the hardest part. You must find a .dav or .bin file that matches your exact model and hardware version.
Batch Config Tool or Hikvision SADP Tool: These utilities help identify and communicate with the camera on your local network. 📂 Step 1: Identifying Your Hardware Version
Flashing firmware meant for a different version of the same model will fail. Open the EZVIZ App. Go to Device Settings > Device Information. Note the Model Number and the current Firmware Version.
Check the sticker on the camera body for the Version (Ver) or Serial Number (SN) prefix. 💻 Step 2: Finding the Firmware
EZVIZ does not publicly host an archive of old firmware. To find a downgrade file:
Official Support: Contact EZVIZ support via email. If you explain a specific bug, they may provide a link to a stable older version.
Hikvision Cross-Compatibility: Since EZVIZ is a subsidiary of Hikvision, some models can use Hikvision firmware, but this is highly risky and for advanced users only.
User Forums: Check IP camera communities (like IPCamTalk). Users often mirror firmware files for popular models like the C6N, C3W, or TY2. 🚀 Step 3: The Flashing Process (Using Batch Config)
Once you have the firmware file (usually named digicap.dav), follow these steps: 1. Connect the Hardware
Plug your camera into your router via an Ethernet cable. Ensure your PC is on the same network. 2. Locate the Camera Proceed at your own risk – EZVIZ support
Open the Batch Config Tool. Click Online Devices to see your camera. Check the box next to it and add it to the managed list using your admin password (the verification code on the camera sticker). 3. Upload the Firmware Select the camera in the tool. Navigate to Remote Configuration > System > Update. Click Browse and select your downloaded firmware file. Click Upgrade. 4. Wait for the Reboot
The camera will progress through a percentage bar. Do not touch the cable or power. The camera will reboot automatically once finished. 🛠 Troubleshooting Common Issues
"Update Failed": This usually means the firmware file is not compatible with your hardware revision.
Device Not Found: Ensure your Windows Firewall is turned off temporarily so the Batch Config tool can "see" the camera.
Constant Rebooting: If the camera loops after a downgrade, try a Hard Reset by holding the physical reset button for 15 seconds. 🛑 Post-Downgrade: Disabling Auto-Updates
If you successfully downgrade, the EZVIZ app will immediately try to "fix" it by updating again. Open the EZVIZ App. Enter the Settings for the camera. Look for Firmware Version.
Toggle off Auto-Update (if the option is available) or ignore the "New Version" prompts. The exact model number (e.g., CS-C3W-A0-3H2WFRL)
The reason you want to downgrade (e.g., lost RTSP, image quality issues)
Do you have access to a Windows computer and an Ethernet cable?
The upgrade takes 3-10 minutes. You will hear:
Do not power off during this process.
Before proceeding, it is crucial to identify why you are rolling back. Common reasons include:
| Symptom | Likely cause | Fix | |--------|-------------|-----| | No response after power-on | Wrong firmware file | Recover via TFTP (Method C) | | “Upgrade failed” in Batch Tool | Firmware version not older (same or newer) | Find an earlier build | | Flashing orange LED forever | SD card not FAT32 or wrong filename | Reformatted as FAT32, use exact naming | | Camera offline after downgrade | Network settings reset | Reconfigure WiFi via app (hold reset to enable AP mode) |
Post-update issues are widespread. Reports include:
While manufacturers encourage users to stay up-to-date, there are legitimate reasons why users seek older firmware versions:
If you have the firmware file (usually a .bin or .zip file provided by the community), you can attempt a local upgrade, which sometimes allows downgrading depending on the bootloader security.
Official EZVIZ policy states that no downgrade methods are provided once firmware is updated for security reasons
. However, technical workarounds exist for advanced users, primarily to restore compatibility with Hikvision/HiLook DVRs or enable ONVIF support. Prerequisites for Downgrading EZVIZ PC Studio : You must use the Windows version of EZVIZ PC Studio Advanced Mode
: The downgrade option is hidden in the "Advanced Settings" menu, which often requires manual activation (e.g., through a specific configuration file in the app directory). Local Connection : The camera and PC must be on the , preferably via Ethernet for stability. Firmware File : You must obtain a compatible If you want
