There's nothing you can't film. I realised this the other day when a hunter asked me which camera he would be best served with for wild boar hunting. There are no hide hunters in loden coats, but "action hunters" out and about through the undergrowth with full-face helmets and boar shotguns drawn.
During the freeride test in Dahab, we tested the cameras in a less martial way, specifically for their suitability for windsurfing. There are basically two design ideas: Firstly, cameras in an external housing modelled on the GoPro. The cameras themselves are usually quite dainty and not particularly robust, and are only protected by the housing, but then properly - 50 metres diving permission is the rule. The second type of camera relies on sufficient self-protection, all flaps and buttons are sealed, making more compact dimensions possible, especially for mountain bikers and snowboarders - but with a diving limit of one metre. This is already tricky for skidding or washing. Contour and JVC also offer additional housings. Sony, Contour and JVc for the helmet. If you want to use the camera not only for windsurfing but also for snowboarding, skiing or biking - and don't want to look like a remote-controlled R2D2 with the GoPro and base on top of your helmet - the flatter housing designs, which can be inconspicuously attached to the side of the helmet, are ideal. A Contour can even be used as a helmet lamp at best.
Two models are already "splash-proof" without an additional water housing. The Sony comes with a proper submersible housing as standard. Another interesting feature for different applications is a variable viewing angle. At least 170 degrees is useful for mounting on a board or rig, while on a bike you may want to look more "forwards", where 120 degrees often works better. Most cameras offer both viewing angles, but not always "full HD" at maximum wide angle. For the widest possible vertical viewing angle (important when windsurfing), the resolution in 960p is often useful in 4:3 format. Operation on the beach or only at the desk While GoPro, Rollei, X-Game and Infinity (all only waterproof with the additional housing) rely on full operability even on the beach in the housing - for every button on the camera there is also one on the water housing - other models look more spartan. Sony only has the start/stop button on the water housing - at least you can remove the camera and find all menu items via a small LCD display, and Sony also has WLAN on board.
