I'm sure its either i need to change one option or the video in ports just aren't working right. I'll go through everything i've tested and how i did so.

I have multiple security systems set up and all of the cameras i'm putting into this DVR were working before i used this DVR. I bought it brand new but was unable to use it for a week because i ended up needing a new power supply for my cameras. After getting the new power supply and plugging everything in there was no video feed. I took the power supply to another Camera setup and tested the power supply and it worked so it can't be that. Then i (just to double check) took one of my cameras that was still in the box and connected it to the DVR with still no video feed. I'm not sure if there is anything outside of just assuming the ports don't work but if you guys have any ideas please let me know.
