Spotlight Cam Pro Plug-In suitability

hi, im considerimg purchasing two of the above cams. They are to be fitted to an external stone wall where the cable hole to the internal power socket cannot be enlarged to enable a UK 240v 3 pin power plug to pass through. Will the power lead for this cam be able to pass through a small hole? I have asked ring customer services bu they have no information and no pictures of the power leads to assist .. thanks in advance
