Changing wifi password

General
1

Hello, I have 16 Aosu Solar cams (C9C Model) on my property. I have 2 acres (mostly wooded) and I have the cameras along the boundary of my property line. I believe my password was breached. I know the quick way to resolve this is to change the password. It appears I have to physically walk the property and input the new password into each camera individually. Is there an easier way to do this? Thanks in advance!
