Looking for child proofing help.

Our baby monitor camera is mounted above the curtain rod with the cord extending down the wall and across to the adjoining wall where it plugs into an outlet behind the crib. The outlet is secured so my daughter can't remove the plug.
However I need a solution for securing the cord to the wall.

The kicker is that is has to be easily removable because the monitor gets taken down and put back up multiple times a month when my daughter goes to visit her grandparents. So i can't install anything that attached to the wall permanently or can't be easily replaced. Picture with arrows to cord and circle where it plugs in. Thanks in advance for your brilliant ideas!
