Until now, if someone were interested in capturing video of their favorite hobby or sport, such as racing, cycling, skiing, Remote Control Cars & Planes, etc., they had no option but to mount a rather large appendage on say, a Helmet or a vehicle, or not use a video camera at all. Some of these sport cameras are the size of a small 35mm camera and protruded as much as 4-6 inches from the helmet. With the ActionCam, being no larger than the typical car remote control, the user hardly knows it’s there, and yet they are recording some great events and memories like never before.
The effects on the user of these large Helmet Cameras can be expressed by simple physics. Torque=Force x LeverArm. The TORQUE is the twisting force that will be acting on the helmet on the individual’s head wearing a large camera appendage. The FORCE comes from the LARGE frontal area of some of these cameras; (2”x3” =6sqin) passing threw the air (F, varies for different speeds). The LEVERARM is the distance the camera is from the mounting surface (approx. 2.5in). So, to fill the numbers into our simple formula; Torque=6F x 2.5, Torque=15F. A simple example of this can be demonstrated is by sticking a hand out of the car window while traveling at speed. As we've all done as kids, you will remember those forces are quite high.
Applying that same physics formula to the ActionCam we are able to see the difference. Torque=1.25F x 1. Torque=1.25F, as can be seen by the numbers, (15F vs. 1.25F) quite a substantial difference, less than 1/10th the amount of force can be seen compared to wearing a larger camera and mount.
Before selecting a Helmet/Sport Cam, individuals should ask the question, "is that the kind of force or distraction I want acting on my helmet while trying to focus or concentrate during my activity?" Sometimes very dangerous activities; check out some of the videos of guys flying in “wing suits”. Now there’s an extreme example! This can also attribute to fatigue as well as have an effect on performance.
