Made myself feel better by researching the CCTV that I want installed.I will be able to get it done in January and pay be instalments by a good company in my area.
It is more than I wanted to pay but worth it for peace of mind,knowing my narc sister can't get into my house again unobserved.I am paranoid that she knows the keysafe code and can't work out exactly when she let herself in and stole the pictures,was it before I changed the locks when she had my spare keys or after and she read my mind for the keysafe code.I am so insecure about this.At least January is not that far away now so will have peace of mind soon.
