Dahua Surveillance Mirroring Setup392

Introduction

Mirroring is a critical functionality in video surveillance systems. It allows users to create redundant recordings of video footage, ensuring that data is protected against potential hardware failures, software errors, or malicious tampering. In this article, we will provide a comprehensive guide to setting up mirroring on Dahua surveillance devices.

Prerequisites

Before configuring mirroring, ensure that you have fulfilled the following prerequisites:*

Dahua surveillance device (NVR, DVR, IPC) with firmware support for mirroring*

Two or more storage devices (hard disk drives, RAID arrays, or NAS)*

Network connectivity between the surveillance device and storage devices

Steps to Configure Mirroring

Step 1: Prepare Storage Devices

Format the storage devices as NTFS or EXT4 file systems. Create a folder specifically for the mirror function on each storage device.

Step 2: Add Storage Devices

On the Dahua surveillance device, add the prepared storage devices as additional storage paths. Specify the IP address or hostname of the storage devices and the folder paths created in Step 1.

Step 3: Enable Mirroring

Navigate to the Storage Management section of the surveillance device's interface. Locate the Mirroring tab and click on "Enable" to activate the mirroring function.

Step 4: Select Source and Target

Select the primary storage path that contains the original video footage as the source. Choose one of the additional storage paths as the target for the mirrored footage.

Step 5: Configure Mirroring Mode

Dahua surveillance devices offer two mirroring modes:*

Primary and Secondary: The target storage device acts as a backup, recording only new footage. When the primary storage device is full, the system will automatically switch to the target device.*

Active/Standby: Both storage devices actively record the same footage simultaneously, providing real-time redundancy.

Step 6: Set Mirroring Interval

Specify the frequency at which the footage is mirrored, such as every 15 minutes or every hour.

Step 7: Verify Mirroring Status

To verify that mirroring is working correctly, go to the Live View section and select the mirrored channel. You should see the footage being displayed from the target storage device.

Troubleshooting Mirroring Issues

If you encounter any issues with mirroring, check the following:*

Ensure that the storage devices are properly formatted and have sufficient free space.*

Verify the network connectivity between the surveillance device and storage devices.*

Restart the surveillance device and storage devices.*

If the issue persists, contact Dahua technical support.

Conclusion

By following the steps outlined in this article, you can effectively set up mirroring on your Dahua surveillance device. Mirroring provides peace of mind by ensuring that critical video footage is protected against data loss. It is a highly recommended feature for any video surveillance system, protecting valuable evidence and ensuring reliable operation.
