I have not done a lot of hunting with video equipment because, I believe for a solo hunter, that it changes the focus of the hunt toward the video aspects of the hunt and not the game being hunted. Another family member or a friend can help or you can pay a camera man or you can get a Tactacam™ Video Camera and mount it to your scope as I am going to do and focus on the hunt.
The Tactacam 5 is “state of the art” has lots of options, is highly rated and looks like a very small spotting scope that can be attached to rifle, shotgun or bow or even a fishing rod. Admittedly, I am not a camera expert but a serious novice. The camera and scope mounting bracket will be arriving next week so I get to mount it on my Leupold Scopes on my .375 Ruger, Weatherby Rifles and on my Excalibur Crossbow scope. It is a push button on and off and can record an hour or more video they say. So stand-by and see what happens when I mount and try to use it.
In the mean time this video I found on the web is very helpful to see all the options this product offers.
Good Hunting!
