 Backup camera

There are two types of RV backup cameras to be on the lookout for:
Wired and Wireless.
Let's dive a little deeper into each type.
Wired Backup Cameras
A wired RV backup camera can be used on literally any RV - motor homes, fifth wheels, utility trailers, travel trailers, and more.
Because this backup camera is wired into your RV, you don't have to worry about losing the signal as much as you would with wireless RV backup cameras (this is especially good if you have a longer RV, keeping the signal is harder the further away it is).
Wired RV backup cameras tend to cost a bit more than a wireless RV camera, however. Especially if you need to have it professionally installed.
Wireless Backup Cameras
Wireless RV backup cameras are the easiest to install. 
They need to be plugged into the DC (12 volt) inside of your RV and boom - you're good!
The monitor is plugged into the cigarette outlet in the console of your RV and come with a mounting bracket or a suction cup to sit on top of the RV dash.
The main problem with wireless RV backup cameras is how unreliable they can be (depending on the size of your RV). Many complain about the signal not being strong enough.
Which Is Better?  It's really up to you!
