I am a farmer in central west NSW and have had 2 of the Oricom wireless reversing cameras for nearly 2 years. I have used them in some very harsh environments from inside and airseeder bin under pressure monitoring seed levels to loading trucks with grain so I can stay out of the dust and know how full the truck is getting. I use these turning a 2 man job of backing one semi trailer onto another to hookup as a road train into a single man job as farmers we only hook our trailers up as a road train once a year for the grain harvest so it is definitely not something we are very practiced in and I never have to get out of the cab until it is coupled into the ring feeder or turntable. I also use these moving oversized machinery on main roads where rear visibility is minimal due to the size of implement behind the tractor. I have used these to reverse grain trucks up to augers for unloading and even monitoring machinery in use to make sure drive shafts are turning as they should. I will eventually kill one of these as I use them in extreme conditions but will definitely be buying another one when I do. The amount of uses is endless on the farm and they are certainly not just a reversing camera they are a movable, relocatable multi use camera that can cope in severe conditions.
