I am using a camera at the top of the extensions of the grain hopper. I just went to an auto parts store and bought a $50 dollar back up for a vehicle camera and mounted that. No more cleaning up the pile of grain on top of the cab!!!!!!
I tried one that supposedly had night vision on the top of the grain tank and you couldn't see jack once the sun went down. It's little lights lit up but they didn't seem strong enough. Agree with you about the dust in the sieves, that was what I kind of meant, should have said dusty instead of dark i spose.
We put a Waeco colour cam on our CTS this summer. Mounted it near the end of the unloader. You can see your front trailer when your on the road and any cars that are behind you. When your unloading into tall trucks, you can see if you overflowing the other side. Going to fit another to view the grain bin & engine bay for next summer.
We run with two cab cam. systems , Our 9770 has three cameras on it's monitor ( 1st. in the Grain Tank , 2nd. for Backing Up & 3rd. pointing down into the grain cart ). The Grain Cart has two cameras on it ( one for backing up and the other pointing down into the truck box.The grain tank and truck box cameras are great !!!! Everything gets filled with no spills.
We've sold lots of the A&I Cab Cam system at the Deere dealer that I work at. Last fall and late summer we had trouble keeping enough in stock. One customer that I know of bought a complete system just for silage cutting. They set the camera aimed at the scale readout in their scale house and the display was placed in the window of the scale house so they could record their weights without getting out of the trucks. Saved them lots of wear and tear on backs and knees.
