The time displayed can be a few hours ahead compared to the actual time.

This article goes about specifically the IP cameras which have the Model name S-CAM or GK-200MP2-B at the Device settings page. This article describes how to solve the issue.

The time should now be correctly displayed

After the installation of the new firmware has been finished the firmware upgrade file gets renamed to rootfs.bin.bak.

If the firmware upgrade fails then try to format the micro SD card at the Device settings of the camera in the eWeLink app first. Then repeat above instructions.
