The wireless system includes a rear backup camera with parking assist functions, featuring marker lines, so you can see obstacles and move around them as you park or backup your RV. The 7-inch touch-screen monitor can display output from up to four compatible cameras, so you can add functionality in the future. A wide field of view, night vision, and motion detection ensure the camera keeps you up to date with what's outside, and the 2.4GHz wireless digital connection supports high-resolution, stable images.
