I installed a Motorolla baby monitor in the trailer today.i have security cameras in the house but the nice thing about this one is it shows the inside temperature and you can set a parameter for the temp that will send you a warning if it is to high or to low. It runs off an app on your phone.you can remotely move the camera to view any part of the room it is in. It will support up to 4 cameras. We got it because we leave the dogs at home when we go out and it gives us the piece of mind should the power go out and the air shutoff.

I had the wireless Furion backup camera installed on the trailer at the rally and it worked flawlessly on the 2250 mile trip home. I was very nervous about getting the wireless one after all the negative reviews. May not have been this manufacturer. All in all worth the money if you do not want to hard wire one

No I did Not get the side camera. You need to drill a 3/4" hole in the cap to access the wiring for the marker lights that I tied the camera to. I wanted to be able to turn it on with the headlight switch There is not much to do in regards to programming.

There are some that you can have up to 4 cameras and a split screen monitor. The reviews on the wireless ones were not great. Hardwired work very well
