Several choices around
Pard007 as suggested
Tactacam5 newest model
The Orion cam is more like the Hero style camera so very good qualiy. Orion is right here on the forum and has put together an outstanding product.
Here is a link where it was discussed a few pages back

One reason I have not purchased a Pard007 or even looked into the Orion stuff is fps. 30fps is just enough for video. If you want to slow it down and have it be of much value for analysis of shots, you need much faster "
frames
per
second". Neither of the above mentioned devices offer that.
And, the GoPro option can get expensive too, because of the mount(s) required and GoPro doesn't have NV. But it does offer 240fps video.
Oh well, I have lived without all this up to now. (chuckle)
