The A100 records up to 4K (3840×2160) at 30 frames per second, producing clear footage suitable for online sharing and cropping.

What mounting and hands-free options does it offer?

The A100 uses a magnetic lanyard pad and a simple back clip so you can attach it to clothing, a helmet, or metal surfaces in seconds. It also has a standard 1/4" threaded nut, letting you use common tripod and sport-camera accessories for poles, helmets, and bike mounts. This makes the camera adaptable for many shooting setups and quick reconfiguration between activities.
