We have a Summer b/w video monitor. It works well for us. The monitor and the camera unit both plug into the wall, no batteries. If I had done my research, I probably would have gone with a portable unit. The monitor is bulky and you have to plug and unplug if you want to take it to another room. Summer does have a portable system which my friend has. It's a hand held device, in color, and they can take it anywhere in the house. It's a bit pricier, but I think worth it.
