I'll preface my question with the statement that I know this question has been asked before (I did a search) but the fact is that digital cameras and specifically HD video cameras are getting smaller and cheaper at a very fast pace.
So, I'm into making cab view videos (in addition to regular ones) of my layout. I email them (or upload them to the cloud) to my grandchildren who live several hours away. They like to see the layout construction progress but they really get a kick out of the view from the engineer's window. For the view forward I have gondola car running in front of an engine. I cut out a piece of pine that fits tightly into the car and inserted a 1/4" screw coming up from the bottom. I attach a small point & shoot camera to it, set it to video mode and I get fairly decent results, albeit it at low resolution. I'm finding that as scenery and tunnel portals are created, the camera is becoming a little too large. Also, I'd like to get better resolution.
I see that there have been a bunch of new tiny HD video cameras coming on the market, many of them under $100. I'm curious to know what others are using to shoot these kinds of videos and if anyone has bought some of those little ones recently, like this one here. I would appreciate a mini-review. I know the Go-Pro Hero's are very popular but they're a lot pricier. Since I have other high-end cameras for standard video, I don't want to spend more than $100 which would be just for this purpose.
