[Troubleshoot] What does the error message "Device is busy" mean?
Please note that this message usually indicates that the camera or NVR/DVR has reached its maximum connection at the same time. Please check if you have shared your account or device with your family or friends. If so, please advise them to log out of the account. If not, please turn off the device and turn it on again, this should solve the problem.
