I know this is an old thread, but I had a similar problem and had to tear apart the old female connector to figure out the pin diagram. I wanted to post this to help anyone else in the future who has a similar issue.
I'm not sure if this will work for all Lorex IP cameras, but it worked for mine:
Lored HD IP Camera for an NVR system - pin diagram:
Lorex Connector - Cat 6 Connector
Orange - Stripe Orange
Yellow - Orange
Green - Stripe Green
Purple - Blue
Gray - Stripe Blue
Blue - Green
Brown - Stripe Brown
White - Brown
Hope it helps someone!
