"Door Thickness Compatibility 34 mm - 55 mm" (Door View Cam), my door is 60 mm

Hi, I have made an mistake, I made an 14 mm hole and thats ok, but my door is 60 mm. I have first seen that yours max is 55 mm, my standard door is 60 mm. Do anyone have any solutions for this, I hope that someone have an extender that I can buy or any other solutions, sine I have made the hole in my door (and my wife is not that happy)? Thanks, Nenad
