ePathChina 2.4GHz Wriessless 7 Inch 800 x 480 TFT LCD Screen Car Rear View Monitor + 420TVL CMOS Backup Camera
It doesn't give me a picture from 40ft away! And the claim up to 70ft, that's a joke! Did alot of work to tap it into my travel trailer running lights and splice the monitor to a 12v cig outlet. Hope I can find  stronger antennas or something to boost the signal! Very unhappy with the product.
