Has anyone ever installed a camera inside a cab?

It can certainly be done.  I have one in an MTH snowplow, and I have a couple that I want to install yet, one in a caboose and the other in an engine.  I need a diesel like an F3 with dual headlights, then I'll use one of them for the camera and the other for the headlight.

Here's a couple of cameras I've used, I have a couple of the top ones waiting for a home, and one of the bottom ones as well.

gunrunnerjohn, how big are those cameras? Do you think they would be small enough to fit in the cab of 2013 MTH PS3 GP7?

Not having the GP7 to look at, I can't really say.  The camera is less than 1/2" square and the length is about 1 3/4" that you need behind it.  The wire and antenna can bend after that.  The other one is about 1" square and 1" deep.

forumite Leighline installed a camera in the cab inside his Williams Sd40. camera looks out the cab glass.

Forumite NTCjoe installed one in his MTH snowplow.

I installed a cube one like the GRJ's second one in the cab of a non-powered MTH SD45. It looks out from the engineer's position. I connected it to run on track power with an adapter available from microcam. Plenty of room in a dummy unit. I doubt it will fit in a powered unit with the can motor there.

do those cameras connect to a wifi?

Any videos of those installed running down the trackage?

I just have Ivor push a wagon containing an old Flip video camera. Fits snugly into one of Lionel's 'troublesome trucks' facing ahead. Or I can tow it from a look behind the train or adjust it to a sideline view. I've also used an old iPhone in the past. No wi-fi. Nothing live. Video exportable or uploadable after a run (then I can edit it a bit too)

Mine broadcast to a live monitor, so I haven't recorded any of it.  I use a small stand-alone camera for recording running sessions.
