New Home Pre-Wire

Hi Everyone, I’m new to this forum and we are looking to build a new home. I met with the low voltage contractor, and they will pre-wire for the POE cameras at all the corners of the house. Is there anything else I should inform them? I’m a beginner and new to this whole process. If the contractor sets up the pre-wiring, is it easy for me to set up the cameras on my own? What else would I need? What questions should I have for them? I want to make sure I’ve got all the required cables, etc., as part of the pre-wire.

Thank you.
