@Jean-Pierre : Merci pour ton idée, je n'aurais certainement pas pensé à des pièce de cerf-volant, je vais chercher dans cette direction.
@JML : Thanks but it seems to me that the RailBlaza system rely on a single pole. I've already tried a pole on a suction cup, and even with a short pole (approx 1ft) there is a lot of vibration and watching the film is a guaranted headache.
