HI
Yes the thread is the same for all video cameras and still cameras 1/4" thread or something.
You will see an improvment in the pics that you will get from your camera as it will be fixed and not hand held.
Are you using it to do Stills or will you be putting it in Video mode? If you do Video I would suggest you get a bullet camera set up.
I can Highly reccomend FastFilms, I use there Bullet cameras and suction mounts on the out side of mine and my mates cars.
HTH
Mark.
