Is there a function that can allow me to delete the NVR recordings manually?


Is there a function that can allow me to delete the NVR recordings manually?


There is no specific function the NVR that allows users to manually delete recordings in the NVR. While there isn’t a dedicated command for this function, you can manage your recording storage effectively by setting the number of days the recordings should be kept on the Hard Disk Drive (HDD).

Please follow the next steps to configure the video retention settings for your NVR device.

Step 1. Log in to your NVR device’s interface.

Step 2. Access the NVR configurations by clicking on the gear icon in the web interface.

Step 3. In the configuration interface, go to the Camera > Recording section

Step 4. Select the camera you would like to configure and locate the section titledKeep recording data‘. Here, you can set the number of days you wish to retain the recordings on the HDD of this specific device.

When you modify the retention settings, the system will begin deleting recordings starting from the oldest folder. This means you won’t lose your most recent recordings in the process. If you choose ‘1 day,’ the NVR will wait until one full day is recorded and then it will start deleting. For example, if recordings were performed on Monday, 1/1/2023, the recordings will be deleted on the next day, Tuesday, 2/1/2023.

new NVR to default and power it off
Export old NVR configuration and power it off*
Remove the disks from old NVR and remember their order
Insert disks to new NVR with the same order and power it on**
Import old NVR configuration to new NVR***

*Our NVR doesn’t support hot swapping, please remember to power it off before remove or insert disks.
**If you operate above steps via local monitor not web browser, please clickSkip setupto avoid disk being formatted.

Not showing correct playback interval


When using VAST-playback to playback the recordings in ND8322P/ND8422P, it didn’t show the recordings in 00:00~01:00.
Please see the attached picture “wrong_playback_interval.jpgfor the problem symptom.


The customer’s time zone settings is GMT+5:30 without daylight saving time.
We found that NVR reply the wrong timezone value(GMT+05:00) to VAST-Playback.


We released a firmware that can solve this NVR problem. Please upgrade to the latest version on the official website.


Why the used space still shows 0 GB even though there are some recordings in that disk?

For our NVR, the used disk volume will only shows integer instead of decimal.
So when the used disk volume is smaller than 1 GB, it will show 0 GB.

How to export videos from NVR HDD to a Windows PC


How to export videos from NVR HDD (Linux based) to a Windows PC?



This guide will explain how to export or copy files from the NVR’s HDD (Linux based) to a Windows PC. A ND8322P and Windows 7 PC will be used for this guide. Important note: turn the NVR OFF before extracting the HDD otherwise it could get damaged.


Step 1. Connect the HDD to a Windows PC (you can use an external enclosure or connect it directly to the Mother board)

Step 2. Download a Linux reader to read ext4 files contained in the HDD, in this guide we will use Diskinternals Linux reader (Download link: ).

Step 3. After you open the Linux reader, it will automatically read all the drives connected to your PC

Step 4. In the Hard Drive section, you will find two Linux Ext drives, each one of them represents a partition in the NVR HDD.

Step 5. One partition contains the media data in where all the videos are stored (/opt/medi/volume0) and one partition contains database information (/opt/database).

Step 6. After opening the /opt/medi/volume0 partition you will find multiple folders, each one containing the recordings accordingly to the camera numbers (Please see NVR camera number designation).

rtaimage 2021 05 09t141648 478 697w512h


Step 7. For example, If you want to export the recordings of camera 11, open the REC-10 file (Note: Cameras are denominated starting from 0, not 1),

rtaimage 2021 05 09t141652 162 585w430h

Then select the folder with the recording you are looking and click theSavebutton.

rtaimage 2021 05 09t141655 675 639w442h

Step 8. Select a folder in where you want to save the recordings, then click theNextbutton.

rtaimage 2021 05 09t141659 505 692w487h

Step 9. After you select the destination folder, the wizard will show you a list of the documents that are going to be exported.

rtaimage 2021 05 09t141847 213 615w494h

Step 10. When the exporting process if finished, you can go to the destination folder and play the recordings.

Important NotesIf the NVR was configured in RAID 3 or 5 you will need to attach all the disks otherwise the software won’t be able to read the partition.

If you were recording with single disk, without doing RAID
You could directly remove the HDD from NVR to other PC, and read the content with LINUX reader e.g

When installing or configuring the NVR HDD for the first time, you will need to create volumes. These volumes will serve as the area used for recording. When syncing an HDD to a volume, the NVR reformats each data block to conform to the volume’s format. Data blocks are like bricks that make up the volume. Depending on the volume configuration (RAID 0, 1, or 5), the blocks will be assigned differentlysome will be divided, while others will be combined.

The syncing process time depends on the size of the HDD used and the time it takes to write each block of data (HDD format).

The NVR’s format at a rate of 20MB/s (block write speed) in order to avoid affecting the NVR functionalities. So, by using the above formula, if you have a HDD of 4TB it will take 27.8 hours to finish syncing.
