HP7 Pro-8MP，How to resolve missing preview images in push notifications?

1 Check Video Encryption Status Go to Device Settings > Privacy Settings > Video Encryption in the EZVIZ App (for some models, the path is Device Settings > Image Encryption) to confirm whether video encryption is enabled. Please make sure the status is disabled; 2 Check Network Connection If encryption is already disabled (status shows "Unencrypted") but preview images are still missing, ensure that both the Wi-Fi network the device is connected to and your phone's mobile data network are stable with good signal strength. 3 Alternative Viewing Method If the issue persists after the above steps, or if the device does not support this feature, it is recommended that after receiving a push notification, open the EZVIZ App directly and go to Library or Event Page to view the full alarm images and video information.
