Model Railroading > Camera Loco ideas

I currently have a high quality camera in service that transmits a live picture to a projector for a simulator I have built.  The issue is the size/weight of the camera and the additional cars needed for power conversion from DCC to DC for the camera and the transmitter. I've watched the drone races and am amazed at the camera size, signal range and quality of picture and also the lack of any delay as this could cause crash issues with a very fast drone. I'd love to be able to fit a high quality camera and transmitter in a SD-45 using track power pickup for camera and transmitter power. I've seen something like that at the Springfield show on the large HO scale modular layout but have lost my contact info . Any ideas or leads would be appreciated.   ----------  Ken
