Here's my video setup on my Tiger. Added the figures too. The camera is an ebay micro camera. About $50 delivered. I attach it to the turret with double sided foam tape so I can take it off easily when I need. I power it with a 9V battery that easily fits inside the turret, even with my gun mods and laser. The receiver is shown, came with the camera. I just prop it up in a window. Next I bought this composite to USB 2 converter which allows me to stream live video to my computer in real time and export video files for editing. About $40 from Tiger Direct (ironic huh ).
So for my telepresence fun I sit in my home office and watch the screen like a tanker would see out their view port and drive around the yard. Even with the house around me the HL transmitter and camera still have about a 200 foot range.

Here's my first video with the setup so no great editing, plot, or carnage. The gun was disabled since the dog has a tendency to attack my tanks.
