Now you can get the thrill of seeing what it’s like to ride inside your trains. The WirelessMicroColorCam produces a full-color image and is available with or without sound. The wireless signal range is 300 to 1000' perfect for most home or club layouts. Tiny enough to be mounted on an N or HOn3 flat car or inside an unpowered HO locomotive (and it’ll fit in a few powered units too). Each system includes the camera, wireless receiver, AC power supplies for the camera and receiver, TV/VCR hookup cables, nine volt battery clip for the camera, one nine volt battery and complete instructions. 2.4 gHz receivers cannot receive 1.2 gHz signals and vice-versa.
