Power supply wiring for Wansview W2 IP cam

Hi,

I'm wanting to use my Wansview 1080P W2 IP cam with Wifi and want to strip out the existing wiring to connect only DC power direct into the camera housing.
- that way I don't need the bulky RJ45 connector block etc.

Can anyone advise which 2 of the cables within the combined cabling supplied with the camera are the DC+ & DC- so I can correctly attach the power supply after removing the shopped cabling & connectors?

Thanks
