Question: The SD card was originally used normally, but suddenly it failed to mount and needs to be formatted repeatedly?
Reason 1. SD card quality issues:
If the quality of the SD card itself is poor, or does not reach the Class-10 level, or the inner size is too small, the SD card may be vulnerable. As the usage time increases, the storage effect of the SD card will get worse and worse, and problems such as inability to write or mount may occur.
Solution:
- Buy a well-known brand SD card
- Make sure the standard is at least Class-10
- Make sure the memory is at least 32GB (supports up to 128GB)
Question: The correct way to insert an SD card?
- Make sure there is nothing in the SD card that you need to backup
- Cut off your device power
- Insert SD Card (Class-10; 32-128GB)
- Connect Power
- Access the "Replay" page of your device, you might need to format it.
Question: No card is displayed in the APP after it is inserted?
- Make sure you’ve inserted the SD card correctly according to the above process
- Power off and restart the camera
- If still fail, try again with another SD card.
Question: No video has been recorded to SD card?
- Make sure you’ve access the right page (replay page) on Netvue App to watch recorded videos.
- If you just inserted the SD card, the device may not start recording, please wait 10 minutes and check again.
- Access the “Micro SD Card” page in the device settings to check the remaining space. If the memory is too small, please replace the SD card; if there are other files in your card, please format it.
Question: SD card recording time?
SD card usage time:
The quality of the SD card and the number of reads and writes will affect the life of the SD card.
SD card maximum write data volume (GB) = capacity (GB) x theoretical maximum write times (500-1000)
SD card recording time:
To record 1 hour of video, requires about 600M of memory.
The maximum recording time of an SD card = capacity (GB) x theoretical maximum write times (500-1000) / 0.6
| Capacity GB | Actual capacity GB | Recordable video duration (hours) | Lower recordable duration (hours) | Maximum recordable duration (hours) | Lower recordable duration (days) | Upper recordable duration (days) | Recommended Duration (days) |
