front view cameras anyone out there have Pyle view cameras

where is the ground is there One?

I am installing camera with my loc pic 2 front 1 rear, The rear comes with a ground the front do not not that i can tell they are pyle view they have a video cable a power wire and then there are 3 wires that are supposed to be to change the view from front to back and to remove the distance lines these are supposed to be red white and black but in reality they are blue white and black.
Questions do all cams have to have ground?
if so could the black wire with the other 3 be the ground?
In the instructions there is o mention of a ground wire, so I am confused, ?

What do you guys think>
