Understanding Dahua DVR Recording Storage

Before diving into deletion methods, it’s important to understand how Dahua DVRs store recordings. Most Dahua DVRs use internal hard drives to save video footage from connected cameras. The amount of storage depends on the hard drive size and recording settings (resolution, frame rate, compression).

Dahua systems typically support continuous recording, motion-based recording, or scheduled recording. When the hard drive reaches capacity, the DVR can either stop recording or overwrite the oldest files—this is called “circular recording” or “loop recording.”

Knowing your recording mode helps you decide whether to manually delete files or rely on auto-overwrite. However, manual deletion gives you more control, especially if you need to remove specific footage quickly.

Method 1: Delete Recordings Using the Dahua DVR Local Interface

The most direct way to delete recordings is through the DVR’s built-in interface using a monitor, mouse, or remote control. This method is ideal when you’re near the DVR and want full control.

Step 1: Connect a Monitor and Mouse

First, ensure your Dahua DVR is connected to a monitor via HDMI or VGA. Plug in a USB mouse if one isn’t already connected. Power on the DVR and wait for the login screen to appear.

If you haven’t set up the DVR before, you may need to create an admin password. Use a strong, memorable password and store it securely.

Step 2: Log In to the DVR

Enter your username and password. The default username is usually “admin,” and the default password may be “admin” or blank—check your model’s manual. For security, change the default password during initial setup.

Once logged in, you’ll see the main live view screen showing camera feeds.

Step 3: Access the Playback Menu

Click the “Playback” button on the screen or press the corresponding button on the remote. This opens the playback interface, where you can view and manage recorded footage.

Alternatively, right-click on the screen and select “Main Menu” from the context menu. Then navigate to “Playback” or “Record” > “Playback.”

Step 4: Select the Camera and Time Range

In the playback menu, choose the camera channel you want to review. Use the calendar and time selector to pick the date and time range of the recording you wish to delete.

For example, if you want to delete footage from Camera 3 on June 10th between 2:00 PM and 4:00 PM, select those options.

Step 5: Locate and Select the Recording

Click “Search” to load the recordings for that time period. The system will display a timeline or list of available clips.

Hover over the recording you want to delete. Some models allow you to preview the clip before deletion.

Step 6: Delete the Recording

Right-click on the selected recording and choose “Delete” from the menu. Confirm the action when prompted.

Note: Some Dahua models may require you to select multiple recordings or use a “Delete All” option for a time range. Be cautious—this cannot be undone.

Step 7: Confirm Deletion and Exit

After deletion, the recording will be removed from the hard drive. Exit the playback menu and return to the live view.

Tip: Always double-check the time and camera before deleting. Mistakenly removing important footage can be costly.

Method 2: Delete Recordings via Dahua Web Interface (Remote Access)

If you’re away from the DVR or prefer using a computer, the web interface is a convenient option. This method requires the DVR to be connected to your local network.

Step 1: Find the DVR’s IP Address

On the DVR, go to “Main Menu” > “Network” > “TCP/IP.” Note the IP address (e.g., 192.168.1.108).

Alternatively, use the Dahua ConfigTool software on your PC to scan for DVRs on the network and retrieve the IP.

Step 2: Access the Web Interface

Open a web browser (Chrome, Firefox, or Edge) and enter the DVR’s IP address in the address bar. Press Enter.

You’ll see a login page. Enter your DVR username and password.

Note: Some browsers may show a security warning. Click “Advanced” and proceed if you trust the device.

Step 3: Install the Web Plugin (If Required)

Dahua’s web interface often requires a plugin for full functionality. If prompted, download and install the “WebComponents” plugin from the Dahua website.

This plugin enables video playback and management features.

Step 4: Navigate to Playback

Once logged in, click on “Playback” in the top menu. Select the camera channel and date.

Use the timeline or calendar to find the recording you want to delete.

Step 5: Delete the Recording

Right-click on the recording in the timeline and select “Delete.” Confirm the action.

Some models may require you to select a time range and click “Delete” in the toolbar.

Step 6: Log Out Securely

After deletion, click “Logout” to end the session. Close the browser.

Tip: Use a private or incognito window to avoid saving login details on shared computers.

Method 3: Delete Recordings Using Dahua Mobile App (DMSS)

The Dahua Mobile Surveillance System (DMSS) app lets you manage your DVR from a smartphone or tablet. This is perfect for on-the-go access.

Step 1: Download and Install DMSS

Download the DMSS app from the Apple App Store or Google Play Store. Install it on your device.

Step 2: Add Your DVR to the App

Open the app and tap the “+” icon to add a device. Choose “DVR/NVR” and enter the following:

– Device name (e.g., “Home DVR”)
– IP address or domain name
– Port (usually 37777)
– Username and password

Tap “Save” to add the device.

Step 3: Log In and Access Playback

Select your DVR from the device list and log in. Tap on the camera you want to review.

Swipe left or tap the “Playback” icon to enter playback mode.

Step 4: Select Date and Time

Use the calendar to pick the date. Slide the timeline to find the recording.

Tap on a recorded segment to preview it.

Step 5: Delete the Recording

Tap the trash can or “Delete” icon. Confirm the deletion.

Note: Not all Dahua models support remote deletion via DMSS. Check your DVR’s firmware version and app compatibility.

Step 6: Exit the App

Close the app or log out when finished.

Tip: Ensure your phone and DVR are on the same network for local access, or use P2P (peer-to-peer) for remote access.

Method 4: Format the Hard Drive (Full Reset)

If you want to delete all recordings at once, formatting the hard drive is the fastest option. This erases everything—use with caution.

Step 1: Back Up Important Data

Before formatting, copy any essential recordings to a USB drive or external hard drive.

Step 2: Access Storage Management

On the DVR, go to “Main Menu” > “Storage” > “HDD Management.”

Select the hard drive you want to format.

Step 3: Format the Drive

Click “Format” and confirm the action. The process may take several minutes.

After formatting, all recordings will be permanently deleted.

Step 4: Reconfigure Recording Settings

Once formatted, set up your recording schedule and motion detection again.

Tip: Formatting is irreversible. Only use this method when setting up a new system or performing a full reset.

Best Practices for Managing Dahua DVR Recordings

To avoid frequent manual deletions, follow these best practices:

Enable Circular Recording

Go to “Main Menu” > “Storage” > “Record” and enable “Overwrite.” This ensures the DVR automatically deletes the oldest recordings when space runs out.

Set Recording Schedules

Use motion-based or time-based recording to reduce unnecessary footage. For example, record only during business hours or when motion is detected.

Use High-Efficiency Video Coding (H.265)

H.265 compression reduces file size without sacrificing quality. Enable it in “Main Menu” > “Camera” > “Encode” to save storage space.

Regularly Back Up Critical Footage

Export important recordings to a USB drive or cloud storage. Use the “Backup” feature in the playback menu.

Monitor Storage Usage

Check available space in “Main Menu” > “Storage” > “HDD Info.” Plan deletions or upgrades before the drive fills up.

Troubleshooting Common Issues

Even with clear steps, you might encounter problems. Here’s how to fix them:

Can’t Log In to the DVR

– Reset the password using the Dahua ConfigTool or by pressing the reset button on the DVR (if available).
– Ensure the username and password are correct. Default is often “admin/admin.”

Playback Menu Not Loading

– Check network connection if using remote access.
– Update the DVR firmware from the Dahua website.

Delete Option Grayed Out
