Hello, Community!
Have a nice day to you!
This topic describes the solution to recording interruption.
Solution
Check whether video preview is normal on the iClient.
Log in to the iClient, choose Basic Operations > Live, and check whether the live video of the camera can be properly previewed.
If the live video fails to be previewed, rectify the fault by referring to the handling procedure in section Failure to Request Live Video.
If the video can be previewed properly, go to the next step.
Check whether a camera online or offline alarm is generated during the recording interruption period.
Log in to the iClient and choose System Management > O&M Center > Surveillance Platform Alarms > Alarm Query.
Set Alarm Type to Camera offline, enter the alarm source name, and set the alarm period. Then check whether the camera is offline when the recording is interrupted.
If a device offline alarm is generated and the camera streams pass through the DCG (the access protocol is HIKSDK or DHSDK), check whether the DCG offline alarm is generated in the time segment.
If so, the camera disconnection is caused by the DCG disconnection. Collect DCG logs and provide them to Huawei technical support.
If not, the camera or the network is faulty.
Run the ping command to check whether the network is faulty. If so, contact the network provider. If not, the camera is faulty. Contact the camera vendor.
If no device offline alarm is found, go to the next step.
Check whether packet loss occurs between the camera and server.
Log in to the iClient, choose System Management > Device Management > Main Devices, and view the MPU to which the camera belongs.
Log in to the CSP OM portal, choose Application Configuration > Configuration Management > Configuration > Application Name > Node, and check the Server IP of the MPU node.
Log in to the MPU node and run the ping Camera IP address command to check whether packet loss occurs.
If no packet loss occurs, go to the next step.
Check whether MU exception alarms exist.
Note:
When the MU is abnormal, the recording storage failure and video loss may occur. Users need to pay attention to the following alarms:
| MU offline | Database connection failure |
| Media server hard disk insufficiency | Storage stream request timeout |
| Stop recording for space insufficiency | Record state exception |
| Storage stream request exception | MU Full Load |
Log in to the CSP OM portal.
Choose Monitoring > Alarms > Active Alarms or Historical Alarms and check whether the preceding alarms exist.
If any of the preceding alarms exits, clear the alarm by referring to the handling procedure in section Alarm.
If no preceding alarm exits, go to the next step.
Check whether storage device exception alarms and other recording alarms exist.
If a slow disk exists in the recording disk, the recording storage failure and video loss may occur. Users need to pay attention to the following storage device exception alarms and other recording alarms:
| Record IO overload | MP storage space full |
| Storage Space Usage Exceeding Warning Threshold | record_integrity |
| Insufficient storage space for safevideo |
Log in to the CSP OM portal.
Choose Monitoring > Alarms > Active Alarms or Historical Alarms and check whether the preceding alarms exist.
If any of the preceding alarms exits, clear the alarm by referring to the handling procedure in section Alarm.
If no preceding alarm exits, collect related logs and contact Huawei technical support.
This is all, thanks for reading!
