1. Check whether the device was working stably during the time period provided by the user, such as whether there were any offline or reboot events that affected the cloud storage event recording of the device. If there were any, inform the user. If not, proceed to the second step of troubleshooting.

2.It is recommended that users turn on the motion detection switch and adjust the motion detection sensitivity to the highest level. If there are still missed recording events, follow step 3 to troubleshoot.

3.Check if the motion detection alarm area switch is turned on, which may cause some events outside the area to not be recorded.

4. If all the above reasons have been ruled out, it may be that the changes in the screen caused by the event are not obvious enough or there is a malfunction in the device's motion detection function.
