NVR doesn't show IP cam image + weird wires

Hello,

First, excuse my English but I am from Belgium and I speak French...

I would like to thank you for your forum and videos on YouTube. They were very helpful for me for making my choice and I finally bought a Hikvision DS-2CD2042WD-I.

I thought that it would be better to have something dedicated for recording and not use my computer hard disk so I also bought a Hikvision DS-7604NI-E1/4P/A and I will be receiving Tuesday a Western Digital Purple 3Tb HDD.

If all of this will work...
