I purchased the dual camera system from Tadi Bros as a wired solution for my Tsunami coach. I knew going to this I was going to have to run the cables which is always a challenge. However I felt the safety and convenience of good back up cameras was essential particularly when towing a 25 Ft horse Trailer. Tadi initially sent the wrong cameras but when I made them aware of this, they immediately sent the correct dual camera system. I was skeptical of the IR night vision capabilities. I endured the days of work and effort to run and snake the cables to the back of the coach. I then installed a simple toggle switch to select the video signal from one camera to the other on the drivers console. I now have had three years of faultless reliability of two rear cameras. One is pointed upward to view above towed vehicles for passing and checking the towed vehicle. The other camera is used when backing out of my heated workshop, backing up to a fence etc. and most importantly, facing towards the tow hitch, I can back onto any trailer without any assistance. I always use the back up camera when back also for safety purposes to ensure no one is behind the coach regardless of the reverse warning sounding off. This was the first modification I did to my coach due to safety concerns and it has paid dividends. If you go wireless or wired, spend the time to do it right as it makes traveling so much less stressful. Oh, I should mention I have 400hp so cruise about 80mph at night so tend to pass most of the rigs on the road hence the reliance on the camera for passing purposes. Hope this is helpful.
