Thank You. this guy bypassed the monitor on his and it worked but guessing he can't adjust the camera .
There aren't any on-screen adjustments that I know of. They're built into the controller. You switch between 3 light modes and turn LED's up or down physically on the box. I was able to make adjustments while hooked to the TV.
I think this is the model I have. Not saying it's the cat's meow of the choices, it's just the one I have.
