I usually get my camera equipment from securitycameraking.com. But they have many learning videos you can view. Look at CCTV Learning center - then downloads - then Video Vault. There is a lot of setup and install information there. Might Help. You would have to decide lower resolution (DVR) or high resolution (NVR - using MP cameras with POE - power over internet) Powered both voltage and video over ethernet cable. I highly recommend POE cameras. Best wishes.
