Description
Generally, NVR setup steps can be divided into: HDD installation, Startup, Initialize HDD, Add cameras, Record schedule setup, Start recording. This is usually how an NVR works. However, sometimes when you want to check the playback or record file, you find nothing recorded or get an error, which may be that you are encountering the record fail issue. The causes of the issue may be: storage issues, network issues or software configuration. Please check the figure below:
NVR record fail causes
Though record fail is the main issue, it’ll also put us in different situations, let’s check them one by one.
Cause
1. Storage issues
The record data is all stored on the hard disks. If the NVR can power on normally, then we need to turn to the hard disk checking.
1.1 Check hard disk status
Go to Status-Disk Status page, check Hard disk current status:
HDD status
lIf the status is abnormal (offline or error), please check the hardware connection (for HDD).
HDD offline
HDD error
For this situation you can try to re-plug the SATA cable, or exchange the cable/port to locate the issue. Also you can replace another HDD for testing.
HDD hardware connection
lIf you configured an NAS storage device, please make sure the NAS server is online,
and the NVR has the permission to access the shared file.
lIf you install the HDD for the first time, it’ll request to initialize the HDD first, click to start , please note that NVR will format the HDD during the process.
HDD uninitialized
lIf you upgrade NVR firmware from 7x.8.0.xx to 7x.9.0.xx, the file system will be changed, it’ll also request to format HDD, please back up record before upgrading.
1.2 Check free storage space
When the NVR runs out of storage, the record will stop if the setting is not correct.
Please check if the Recycle mode is enabled on the NVR.
HDD storage
Recycle mode
Another place to check is Storage mode setting. The Quota and Group setting will also affect the record. Make sure the remaining space for the channels is still sufficient.

2. Network issues
If there is no storage issue on the NVR, the HDD status is all normal, then we move to network part.
2.1 Channel connection status
Please view the Camera Management page and check the status. If it displays , it indicates the status is OK. If it shows , there might be an error. Please make sure the camera is still online, and the login info is still correct.
Camera status
Login authentication
2.2 Check stream type
Go to Setting-Video Record-Record Settings page and check the record stream type. Make sure the selected stream type is available on the live view page. The same when you check the record on playback page, select the correct stream type to get the record data.
Record stream type setting
Also check if the stream type is enabled on the camera:
Camera stream type setting
Playback stream type setting
3. Software configuration
3.1 Check time setting
Please make sure the schedule time and NVR system time can match each other. Otherwise the record will not start correctly.
NVR system time setting
Camera system time setting
Record schedule setting
Note:
- 1. The record schedule is based on the NVR system time.
- 2. It is suggested to set the NVR and camera to the same time zone. If not there would be time difference in viewing the playback.
3.2 Check the record type
Please make sure the record type in schedule is correct. You can check the color on the right side, each color standing for different record type.
Record type setting
Note: General record contains the Event record. But if you only setup the Event record, the record will only be triggered when the event happens.
3.3 Event record
Milesight NVR supports event record feature. After setting up the event record, the NVR will start to record when an event happens. Here we take the common event motion detection as an example, to see how to make event record work correctly.
Motion detection configuration
Milesight camera
For Milesight camera, it’d be easy to setup motion detection on NVR interface. Firstly, please check the Motion detection setting, make sure motion detection is enabled and the detect schedule setting is correct.
Enable motion detection
Motion detection schedule
Third party camera
For most of third party cameras, the configuration steps are similar to Milesight cameras.
Please try steps above first and check if it could work, please make sure the camera is added via ONVIF protocol.
Sometimes due to the different code framework, some interface might not be matched between NVR and third party camera. Take Hikvision camera for example, the camera can be added successfully via ONVIF protocol.
Hikvision camera is added successfully
However, NVR cannot read its motion detection configuration normally, shown as below picture:
Data match fail
For this situation you can configure the motion detection from camera directly:
Motion detection setting on Hikvision camera
Note: To confirm if the setting is correct and effective, you can check if NVR can receive motion detection notification from the cameras successfully. Go to logs:
Event log
Record schedule
After the motion detection configuration is done, please don’t forget to setup the record schedule. We can select Event record or Motion record in this case.
Event record schedule setting
Others: If you are using third party cameras with Milesight NVR, and you meet record fail issue, please try troubleshooting methods above first. If all doesn’t work please contact Milesight support team.
