1, Check if there is any error hint. Please move to step 2 if no error hint. If the error hint is ‘No link’, it indicates the problem is caused by IPC off line, please refer to IPC troubleshot. If the error hint is ‘No resource’, we can lower main/sub stream resolution to solve it.
2, If there is not any error hint, we could upgrade IPC firmware version and test again.
3, Besides, please go to Configuration / Live view / View to check if the IP channel is banned (‘X’ means banned).
4, If the problem remains after step 1 and step 2, please contact with technical support engineer for further support.
