If you use a video monitor at home, what do you use when you are traveling? If we are staying somewhere besides a hotel (where we are all in the same room) we bring the monitor, but since it's mounted to the wall, it's a pain to unhook the camera and wires every time. I would like to just buy a second camera but they are at least $60 so it seems silly. Considering buying an inexpensive sound only monitor- any recommendations?

What do other people do? We definitely need something if I don't want to be tied to sitting within earshot of wherever she is sleeping.
