I guess it depends on the quality of footage you want. A bow or gun mounted camera, isn't going to "consistently" produceanything more than sub-parresults. Plus the effects of the weight to the bow, can be a problem in itself. But for one just to look at or review the shot, etc. then it may be fine. To consistently get"good orprofessional"footage, a cameraman is needed. It can be tough to get good footage even withthe cameraman. Trying to hunt and camera at the same time, usually ends with one or bothitems(video and/or hunt)being deminished....

Just depends on the quality of footage you're looking for.
