For advanced users: Ezviz formerly released a Batch Configuration Tool for Windows that could push custom firmware.
Note: Newer cameras block this method unless you enable "Enable downgrade" in the hidden maintenance menu (not available on most consumer models).
Ezviz cameras are renowned for their reliability, crisp image quality, and seamless integration with smart home ecosystems. However, like all connected devices, firmware updates are a double-edged sword. While manufacturers release updates to patch security vulnerabilities and add features, sometimes an update can break more than it fixes. You might experience Wi-Fi disconnections, a clunky new interface, reduced two-way audio quality, or even compatibility issues with third-party software like Synology or Blue Iris.
When this happens, users find themselves searching for one specific solution: Ezviz downgrade firmware.
In this comprehensive guide, we will explore why you might need to downgrade, the risks involved, step-by-step instructions for various Ezviz models, and critical safety tips to avoid bricking your device.
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.
Downgrading firmware on EZVIZ cameras is often pursued when new updates accidentally disable useful features like RTSP or ONVIF support, which are essential for connecting the camera to third-party Network Video Recorders (NVRs).
Since the official mobile app only supports upgrades, a downgrade requires using the EZVIZ PC Studio software and a specific "Advanced Mode". ⚠️ Essential Precautions
Risk of Bricking: Installing incorrect firmware can permanently disable your camera.
Stability: Always use a stable power source and, if possible, a wired LAN connection during the process.
Verification Code: You will need the 6-digit verification code (found on the camera's sticker) to access advanced settings. Step-by-Step Downgrade Guide 1. Preparation: Get the Right Tools
Download EZVIZ Studio: Install the desktop version of EZVIZ Studio from the official EZVIZ Download Center.
Acquire the Firmware: You must find an older .dav firmware file specific to your camera's model (e.g., C6N, C3A).
Note: EZVIZ does not publicly host older versions. Many users find these on community forums like IP Cam Talk or specialized local support sites. 2. Enable "Advanced Mode" in EZVIZ Studio ezviz downgrade firmware
By default, the upgrade/downgrade menu is hidden. To reveal it:
Navigate to the installation folder of EZVIZ Studio on your PC (usually C:\Program Files (x86)\EZVIZ Studio\config). Find the file named AppConfig.ini and open it with Notepad. Add the following lines under the [LocalOperation] section: Show=1 Use code with caution. Copied to clipboard Save and restart EZVIZ Studio. 3. Perform the Downgrade Log In: Open EZVIZ Studio and log into your account.
Access Advanced Settings: Look for the "Advanced" button under your camera's thumbnail. You will likely be prompted for your camera's 6-digit verification code.
Navigate to Maintenance: Go to System -> System Maintenance.
Upload Firmware: Select your downloaded firmware file and click "Upgrade" (even though you are technically downgrading).
Wait: The camera will reboot once finished. Do not disconnect the power. 4. Disable Automatic Updates
If you do not disable auto-updates, the camera may automatically re-install the newer firmware overnight. Open the EZVIZ mobile app. Go to Device Settings -> Device Version. Toggle "Auto-Upgrade" to OFF. Alternative: Restoring RTSP Without Downgrading
Some recent updates allow you to re-enable features like RTSP through the app's LAN Live View settings without a full firmware rollback:
In the mobile app, go to your Profile -> Settings -> LAN Live View. Scan for your camera and enter the verification code.
Look for Local Server Settings and manually toggle RTSP back on.

Navigating EZVIZ Firmware Downgrades: A Balancing Act Downgrading firmware on EZVIZ devices is a complex topic that sits at the intersection of user control and digital security. While modern tech companies typically push users toward the latest updates for security reasons, certain technical needs—such as maintaining compatibility with older recording hardware—drive a segment of the community to seek ways to roll back their software. The Challenge of Modern Security Policies Officially, EZVIZ maintains a strict policy does not provide firmware downgrade methods For advanced users: Ezviz formerly released a Batch
once a device has been updated. This stance is primarily driven by security; newer firmware often contains critical patches for vulnerabilities that older versions lack. From a manufacturer's perspective, allowing downgrades would expose users to known risks and potentially compromise the integrity of their smart home ecosystem. Why Users Seek Downgrades
Despite the risks, there are practical reasons why a user might attempt a downgrade: Legacy Hardware Integration
: Some users find that new firmware versions disable specific protocols (like RTSP) or features required to add cameras to older Hikvision DVRs or NVRs Feature Regressions
: Occasionally, an update may introduce bugs or remove a specific interface layout that a user preferred. Third-Party Software Compatibility
: Specialized surveillance software might only be compatible with a specific older version of the camera's internal software. Technical Methods and Risks Since there is no "one-click" downgrade button in the , advanced users often turn to manual methods: Manual Flashing via SD Card : This involves downloading a specific firmware
file, placing it on a microSD card, and using the camera's hardware reset button to trigger a manual flash. EZVIZ Studio (PC) : Some older versions of EZVIZ Studio
offered more "Advanced Settings" than the mobile app, occasionally allowing for firmware management that is now restricted.
These methods carry significant risk. Flashing the wrong firmware or experiencing a power failure during the process can "brick" the device, rendering it permanently unusable. Firmware Upgrade and Support Policy for EZVIZ Products
If the downgrade fails and the camera only flashes red:
Use if camera is stuck in boot loop with steady red LED.
Sometimes the new firmware demands a newer version of the Ezviz app. If you are running an older phone or prefer an older app version, the camera may refuse to connect.
The upgrade takes 3-10 minutes. You will hear:
Do not power off during this process.
