It had taken us quite some time to find a suitable helmet camera system to equip our racing team The quality most systems offer just wasnt good enough for us or recorder and camera were seperate or the system was just too expensive But then we came across the ContourHD system which has managed to convince us and we dont want to keep this useful stuff from you any longer The cam is an all-in-one system and records in 720HD quality Here you can see a test video  body made of sturdy aluminium  90degree rotating lens  an assortment of brackets allow for mounting the cam to helmet fairing or handlebar  camera can be mounted at left or right via a rail  recording on microSD memory cards  removable rechargeable battery lasts ca 1h  big record switch on the top simply activated by sliding easy to use even with gloves  import to PC via USB cable  Format directly compatible with youtube For us this is the best price_performance ratio on the market right now
