Good question. If you do any kind of snow plowing you will want to keep the lens as high as possible. The machine I plow snow with in the winter is a Caterpillar with a factory camera. When driving the machine down the road, snow likes to build up on the lens. Which is located in the top center of the rear door, or just above the rear door, cant remember for sure. This camera has the option to turn on only when using reverse, or it can be left on all of the time. I found out the camera works better when its dark out vs daylight hours. Too much sun glare off the snow in the daytime makes for a pretty bright screen. I've never used this machine during the summer since its a rental.
