I would like to be able to video hog hunting and shooting prairie dogs with a gun mounted camera. Hog hunting would not be through a scope, just regular video, but shooting from a vehicle, off-road, at speed, can be pretty rough on equipment, so would need to be pretty sturdy & hopefully pic rail mounted. Due to the distances in prairie dog shots, I would like to be able to video through a scope. I have a new i-phone & getting used to it after having a Droid, but know very little about what's available in video equipment. Any suggestions appreciated.
