Charging my stickup outdoor cam gen 2

I just bought an AC adapter for my outdoor stickup cam gen 2 .

How do I tell if it’s charging. The battery level has been dropping daily.

This is the adapter i got,

Hi @Danuka. Make sure that the power adapter is firmly plugged in on both the Camera and at the power outlet. Ensure there is no dirt or debris on either side of the connection. After doing so, try resetting the Camera by holding down the setup button for at least 20 seconds. Once the reset is done, set your Camera back up in the Ring app using the steps under Set Up a Device. Test out a Live View or a motion event to see what the Device Health page is reporting.
