It is the classic Friday afternoon security headache: you are standing in front of a client’s server rack, or troubleshooting your own office surveillance system, only to find yourself completely locked out of your Network Video Recorder (NVR). You try your standard passwords, then a few variations, but you keep getting hit with a login failure screen.

As a security technician, I can tell you that password lockouts on Uniview (UNV) NVRs are incredibly common. Fortunately, Uniview has built robust, secure, and professional pathways to reset and recover administrator access without deleting your precious video recordings.

In this comprehensive 2026 guide, we will walk you through the professional methods on how to reset Uniview password credentials for NVRs. Whether you have access to the original recovery email or need to request a master recovery key from the official manufacturer portal, we have got you covered.

The Critical First Step: Inspecting the Login Interface

Before attempting a reset, you must first determine which recovery options are available on your specific Uniview NVR.

Walk up to the physical monitor connected directly to the NVR (or pull up its local IP address on a web browser). Go to the login screen and click "Forgot Password".

Take note of what displays next:

A QR Code with a Partially Masked Email: This indicates a recovery email was linked during setup. If this email is yours, you can complete a self-service reset in under five minutes.
A QR Code with "Email Not Set" or "Please set linked Email": You must generate an official recovery request using the NVR’s Serial Number and system date.
Security Questions: Older or non-cloud firmware versions may prompt you to answer the security questions established during installation.

Method 1: The QR Code Recovery Method (Using EZView or UNV-Link)

If a recovery email was linked to the NVR during its initial configuration, you can use Uniview's mobile apps (EZView or UNV-Link) to instantly send an unlock code to your email inbox.

1.Access the Forgot Password Screen:Step 1.

On the NVR's local interface monitor or web browser page, click the Forgot Password link. A window containing a unique QR code will appear.

2.Open Your Mobile App:Step 2.

Launch the EZView or UNV-Link app on your smartphone.

On EZView: Navigate to Me > General > Forgot Device Password.
On UNV-Link: Navigate to Me > Tool > Forgot Device Password.

3.Scan the QR Code:Step 3.

Grant the app camera permissions and scan the QR code displayed on the NVR's monitor. The app will instantly signal the server to transmit a security reset code.

4.Retrieve and Enter the Code:Step 4.

Check your registered email inbox (and spam folder) for a message from Uniview containing a 6-digit verification security code. Input this code directly into the Security Code box on your NVR screen and click Next.

5.Generate Your New Password:Step 5.

Create a strong, new administrator password. Once confirmed, the system will update, and you can log back into your NVR without losing your configuration settings or recording archives.

Method 2: Official Portal Reset (If the Recovery Email is Inaccessible)

If you have inherited a Uniview system from a previous property owner, or if the original installer used an email address you no longer have access to, Method 1 will not work. Instead, you must request a temporary master password directly from Uniview's support infrastructure using their official reset portal.

Retrieve Device Info: Download and install the free EZTools software on a computer connected to the same local network as your NVR. Run a search to identify the NVR's exact Serial Number (SN) and the current System Date.
Pro-Tip: The NVR's internal clock is crucial. If the internal CMOS battery has drained, your NVR might think the year is 2000. You must use the exact date displayed on the NVR screen for the security code to validate.
Take a Photo of the QR Code: Go to the "Forgot Password" screen on your local monitor and take a clear, high-contrast, straight-on picture of the QR code with your smartphone.
Visit the Portal: On a computer, navigate to the official Uniview Product Password Reset Portal.
Submit the Request: Fill out the verification form by entering the NVR Serial Number, Model Number, Current System Date, and uploading the photo of the QR code.
Apply the Master Password: Uniview's automated support system will verify your request and email a temporary security code or master override password directly to you (typically within a few minutes to an hour). Use this temporary key to log into the NVR immediately and set a fresh, permanent password.

Method 3: Resetting via Security Questions

If your NVR is not connected to the internet (a common scenario for highly secure offline networks in local commercial warehouses), it cannot transmit emails to a cloud server.

For offline units, you can click on "Security Questions" on the Forgot Password interface if they were configured during setup. Successfully answering these security questions will immediately unlock the interface and prompt you to set a new admin password.

What Happens to the Cameras After an NVR Reset?

One of the most common issues after an NVR reset is that all of your connected IP cameras suddenly drop offline. Why does this happen?

┌───────────────────────────────┐
│       Uniview NVR             │ (New Admin Password: 'MyNewSecurePW123')
└───────────────┬───────────────┘
                │
     [PoE Switch Subnet]
                │
┌───────────────▼───────────────┐
│      Uniview IP Camera        │ (Still locked to Old Admin Password!)
└───────────────────────────────┘

When you reset the NVR, you change its administrative password, but the physical IP cameras plugged into the back of the recorder (or on your local network switch) are still expecting the old password. To fix this, you must log into each camera's web interface individually, perform a hardware button reset on the cameras themselves, and re-add them to the NVR with your new credentials.
