The Cambox Xtrm is about 4 times lighter than other action cameras: 38 grams for the Cambox Xtrm2 and 40 grams for the Cambox Xtrm3.
This relatively low weight allows it to be fixed under all types of helmets and even under a cap!Which is impossible for the other on-board cameras!
The Cambox Xtrm's light weight prevents the helmet from tipping over, ensuring stability and safety.
