You can purchase cloud storage service based on your requirements. For example, if you purchase a 7-day event package, the cloud stores your videos from the latest seven days and deletes the videos that have been stored for longer than seven days.
Event recording mode and continuous recording mode are different in how they trigger the video upload. An event recording mode uses the event triggering mechanism, that is, when a device detects a change in a video image, it uploads the video data to the cloud. A continuous recording mode uses the continuous upload mechanism, that is, a device continuously uploads video data to the cloud 24 hours a day.
The service may be valid for one month or year. Within the service validity period, you can view videos stored on the cloud.
Based on the above characteristics, you can choose according to your personal needs.
