Best Dash Cam with Collision Detection
A dash cam with collision detection uses a G-sensor or impact sensor to detect sudden force and protect important footage. This helps preserve accident clips during road incidents or parked vehicle impacts.
Collision detection is one of the most important dash cam safety features for accident evidence and parking protection.
