I have been wanting a backup camera or cameras, to aid me in hitching up... as well as stopping in the correct spot at the campground.
I have also been reading everyone's post on the camera(s) systems they use, or have experience with both wired and wireless. From what I have been able to ascertain with wireless systems is lack of range when mounted at the back of the trailer, which lead either to loss of pic or distorted/fuzzy pictures.
I didn't want to wire a system in, either on my tow vehicle or trailer.....so that left me with the wireless option. In my thinking, a wireless system didn't need the camera or monitor tied to a power supply...thus needed to be battery powered or rechargeable. Because of this requirement, it omitted many of the wireless home surveillance systems that might could have worked on the truck/trailer as well, because most of these require 120Volt power to use.
If I haven't bored you to death yet, here is what I found in my local Wally World the other day, the GE Wireless Home Monitoring Kit #45255 for $140.
GE Wireless Color Camera and Monitor: Surveillance Equipment : Walmart.com
Here is why I got it:
The color camera and handheld monitor can be run off of 120 volt with included power supplies, or the monitor has built in batteries that can be recharged, while the camera can run off of AA batteries.......thus they don't have to be hooked to a power supply.
The package says the connection is 2.4 Ghz with a 450 foot range. I have used it from one end of my house to the other and it works with no problem, as well as placing the camera on the back and underside of my camper (pics below) with no problem. The monitor has a flip up antenna to help the range.
The camera also has night vision, that works.....as well as a two way intercom built in so you can talk/hear from the camera and monitor....but from what I have been able to tell the sound may not be so great outdoors.
If you put in a micro sd card in the monitor, you can record video from the camera (which is what I did to get the pics below)
Another plus is, you can add up to three more cameras to the system for four total that can be seen on the monitor. However these extra cameras were $80 a piece.
What I did was just place the camera base into one of those magnetic base tool/parts bowls and run a few rubber bands around it. After that, I could just stick it on my tailgate (as seen in pics), or on my back bumper of the trailer, or underneath the trailer to see my rear electric stabilizers.
I took the three videos while the monitor was on the dash of my truck. I have lost some of the picture quality by taking screenshots of the videos while they were paused in windows media player.
Anyhow, I can't testify yet to the durability or life expectancy of the system....but just letting everyone know if they want to test it out. You can also use the system for other things once you get to the campground, and be able to record it.
P.S. The camera will also play four lullabies and has a built in nightlight, if you can't sleep on your camping trip.
