Find replacement part for spotlight Cam wired

Hello, I am writing to you as a customer from New Zealand. I purchased a Spotlight cam wired model **2520AH620L-B04FX** To make a successful installation i had to drill a hole in a brick wall, remove the end of the electrical cable and push it through the hole. After one end of the cable was on the outside of the house, i had to re-install the electrical part of the camera. I was successfully able to set up the camera. I moved house and i had to remove the cable once again. This time during the move, i lost a small part of the electrical wire. I am attaching pictures in case anybody know the name and where to get the replacement. please look at the pictures below.
