I rang out one of the Micro USB to Ethernet cables that are supplied with the camera system. The four conductors at the Ethernet end are connected as follows:
Ethernet Pin Micro USB Pin
6 4 and 5
This is the official pinouts for the MicroUSB devices. In blue is the CAT5 side of the cable, green is the MicroUSB side of the cable. Orange column is the camera (we strongly recommend against cutting the ends off of the cable.
