Hi, Robin
According to your version, this may be a known problem.
For details, see the following cases:
【Problem Analysis】：1. We checked the VCN server by remote, and found this is a software issue.
2. And the new version will solve this issue.
【Root Cause】：This is a software issue.
【Solution Description】：The new version V100R002C50SPC270 has come out.
You can upgrade to this version.
Other possible causes of video loss are as follows:
1. Check whether the disk space is full. Check the disk full coverage logic.
Table 1. Recording storage policy parameters
[tr]ParameterDescription[/tr]Insufficient Recording Space Policy
| The options are as follows:
- Stop if insufficient: Only recordings whose retention period expires are recycled. After the storage space is used up, recording stops.
- Overwrite if insufficient: Recordings are recycled in the following sequence until the available storage space is greater than the threshold: recordings whose retention period expires > recordings whose retention period is not configured > earliest recordings within the retention period.
|
Video recycle policy
| The options are as follows:
- Recycle by storage space: When the available storage space is less than or equal to the threshold, recording recycling is triggered.
- Recycle by expiration time: When the retention period expires or the available storage space is less than or equal to the threshold, recording recycling is triggered.

2. Check whether the recording plan is set correctly.
3. Check whether the hard disk status is normal.
4. Check whether the system time is inconsistent with the device time.
5. Check whether the video cannot be sent back to the VCN due to network exceptions.
6. Check the power supply of the camera.
7. Check the DCG and MU logs. Check whether the DCG receives the 0x0501 flow request from the MU.
8. Request R&D assistance.
According to the picture you have provided, the problem is likely to be caused by 5 or 6.
To solve this issue, you need to fix the network or power supply problems.
