Go-Pro is good but there are some weak points
As a motorcycle and 4-wheel vehicle driver in a country with some of the worst drivers world-wide I have two Go-Prp's in the body of my two-wheeler plus a helmet mounted unit. My employer also a further 9 units on company wheels. I also switch them to my utility vehicle when I go on long trips.. They are used for continuous recording of driving events (crashes, police collecting bribes, etc.)
Go Pro is definitely up there in the leaders, I had a couple of Oregon Scientific but they don't repair their products. Go Pro has numerous accessories but I recommend you buy the HD HERO Naked Kit as it has a broad range of general accessories including a spare lens (that can easily get scratched as they project to the front). I also recommend a spare case (the camera itself has no mount and you need the lens built in the plastic protective case to achieve focus), and a spare battery or two - recharging from a USB jack takes overnight. The ONLY good thing about the Oregon Scientific unit was the fact it used AA cells.
Other things to note:
1. Only one specified SD chip will enable all functions;
2. The camera housing lens fogs up (industrial goggle cleaner eliminates effect);
3. The all-plastic mount is easily broken by snatch thieves;
4. Buy extra batter packs;
5. None of the GoPPro specialised housings such as Helmet HERO, Motorsports HERO, Surf HERO or the chest mount are sufficient to withstand theft (sharp twist and the base snaps), crashes involving a car (the camera flies off), violent waves can also crack the base and cause the camera to fall off, and when used on the chest there is no protection.
6. To prevent (5) I had several stainless wire cages fabricated in which the camera is located. I also had a compatible mounting base (the part that attaches to the helmet, car, bicycle) machined from aluminum/aluminium so the camera is secure under all circumstances.
7. Cords are provided but can only be used when the camera is not in the case - I made up right angle connectors which can be used with the non-waterproof case;
8. The base on which the camera is mounted in it's packaging is great as a spare base.
The Canadian Broadcasting Corp. has used the GoPro as a POV (Point Of View) camera mounted to Ski Dooers on the highest setting and used the recording for TV broadcast.
It handles all types of daylight, well lit indoor scenes and brightly lit streets - it is terrible on poorly lit streets - as found in UK villages and towns..
As long as you now GoPro limitations, you'll be happy with it. Use a demo in a store IN THE DARK CORNER and check it out.
Notwithstanding it's shortcomings, I would recommend it and will buy another unit or two when I am in a country with a distributor. Good luck!
