Hadn't thought about that aspect of the camera man, but do agree I've seen them in videos tip off the "shooter" on an incoming deer. What if they have a tag but it has been filled? Such hair splitting.
My understanding, FWIW, is that anyone without a license can accompany a licensed hunter while hunting, but CANNOT assist in the hunt in any way. But this is one of those scenarios that I suspect is interpreted differently by different CO's. (Don't get me started on that topic.

)
A prime example is two guys turkey hunting...one licensed, one not. Everything is cool until the unlicensed guy "participates in the hunt", which could include calling, spotting the game, advising the licensed hunter, etc. Two licensed hunters, even if one has filled his tag for that season, have a lot of freedom and the "tag filled" non-hunter, can assist in the hunt.
Technically, very technically, an unlicensed cameraman is stepping over the imaginary line a bit when he calls attention to approaching game for the licensed hunter...but I have yet to hear about that being pursued anywhere as a problem. Keep in mind, that it is common for the cameraman to also have a valid license for the season that is in, not always though, but pretty common. At which point, they can freely participate in the hunt, even if their tag is filled, as long as they are in the right season still.
Now then, pushing deer, rousting pheasants, calling turkeys, etc...that is well past the line and would likely draw a fine/warning. Again, this is probably one of those areas that you could get different answers on depending on who, and when, you talk to. But I went into this extensively back in the day with a CO because I often "guided" various friends and family members while spring turkey hunting...sometimes when I I had an active tag, or filled tag, but still in that season and sometimes just because some rookie hunter didn't know how to hunt them and/or have access to areas with turkeys and while I didn't have a tag for that season, I loved going out spring turkey hunting.
