I also got mine from SJT Enterprises,

The camera comes with a 9-volt battery. I didn't want to mess with changing batteries, so I got the DCC-compatable power supply along with it. I mounted this in a Proto 1K R-17 subway car. This is one of the unpowered cars. Here's the car, camera unit and power supply board as they came originally. (Click on the pictures for a bigger view.)
No, this stuff didn't all fit. The jack at the end of the black wire coming off the camera takes another plug, and that connects up to the 9-volt connectors on the power supply. I couldn't fit all that connecting hardware, so I swapped e-mails with Jerry at SJT, and for $15 (really good deal) he rewired it to my specifications, including shipping it back. Note that there's a small circuit board embedded in the jack, so it's more than just snipping wires and re-soldering some connections. This is what came back about a week later:
The capacitor has been moved off-board, too. I installed the board inside the gray box in the center of the car. (That's where the motor is in the powered version.)
This is the nose-on view of the car. The camera is in the center porthole. The large gaping holes at the bottom are for the LEDs, which haven't been installed yet. I removed the original silly incandescents and put in small LEDs to get more lighting in the tunnels.
I installed small slide switches on the bottom of the car to independently control the lights and the camera power. I don't run the receiver very often, so I don't want to put more hours on the camera when it's not in use.
The camera is sensitive to heat. I had to remove the front window glazing, and take out the interior lighting at the front of the car, too. Even so, the picture does deteriorate after 10 or 15 minutes of running, but it recovers if I let it cool down again. (This is one good reason to just put it on a flat car, by the way.)
I run mine with a 30-inch standard old-style TV. It looks great, and always gets a big "Cool!" when I show it to visitors.
This is my YouTube video. It was taken some time ago, before I finished a lot of the scenery. At that time, the camera was sitting in a gondola, which is why it tilts a bit towards the end. There were no front lights on the gon, either, but you can get an idea of how these work.

It takes an iron man to play with a toy iron horse.
No i push it around the layout on a flat car in front of the Loco
It does have an amazing depth of field

Great little camera !
Takes about 2 hours to charge and will run about 50 min on one charge
the broadcast range will vary depending on the number of obstacles
About 200 ft max
it will transmit while going thru tunnels
And yes it has sound
