Clips for new Indoor Cam power cable wiring - What are you using?

I would like to find nail on / screw-on white clips to hold the power cable snug to the wall. I found some at Home Depot, but they do not fit snug to the wire, which allows for a lot of "slack" in the wire and looks rather unsightly. Has anyone found white clips that are small enough so the wire is snug between the clips and looks "neat" on the wall? I have attached a photo of what I am currently using. Ring does not include any wire clips for the Indoor Cam.
