If you're encountering difficulties charging your EZVIZ camera, here are some steps you can take to troubleshoot the issue:

1. Check the power source: Make sure the power outlet you're using is working properly. You can also try plugging the camera into a different outlet.

2. Check the power cable: Make sure the power cable is not damaged or frayed. You may also try using a different charging cable to see if that solves the problem.

3. Reset the camera: If there is still remaining power in the camera, you can try resetting the camera by pressing and holding the reset button for about 10 seconds. This will typically restore the camera to its default settings and may help resolve any charging issues.
