Took a trip to Hot Springs Arkansas earlier this week and the camera(s) did great. I ended up mounting one in the back window of the trailer, and it helped me a lot in seeing who was behind me and where.
I had previously added a 12 volt outlet to my trailer, that is controlled by my aisle light switch on the control panel. I leave the camera turned on at the camera itself, then just use the control panel switch to turn the camera on/off when traveling...thus don't need to raise my blinds or climb over the recliners to mess with the camera. Just reach inside the trailers door to turn the camera on/off. I also now have the camera powered by the trailer battery, and thus don't need AA batteries or a 120 volt connection.
Here is the forum where I added the outlet:
Adding a 12 volt outlet for the wireless camera
I went to Radio Shack and bought their 6 foot long Enercell cord #273-348 and then picked out the corresponding plug which is a type H, to fit the GE camera. Radio Shack gives one plug per cord, so it cost $12 for the cord and plug.
Note: when you look this model number up online it states it is a six inch cord, but it's six foot.
I then did as BarryD0706 has stated previously and found a 5 volt cell phone car charger I had from past phones (since most cellphones use 5 volts like the camera does) and cut the phone end off it. I also cut one end off the Radio Shack cord, then spliced the Radio Shack Cord to the car charger cord..........making sure I had the polarity correct.... which is positive on the tip end of the car charger and positive on the inside of the Type H end.
I mounted the camera to the back window by using a T-bracket screwed into the window frame, then covered this bracket with stick-on velcro, and placed the other velcro side on the camera base.
Here are some pics showing the mounting, and cord splices.
Make sure you do not use anything that supplies a full 12 volts to the camera, as it needs 5 volts.
