Dashcam

A dashcam records continuously to local storage, retaining footage for a rolling period and preserving clips around trigger events such as harsh braking or impact. Commercial installations often use a multi-channel MDVR covering the road ahead, the cab, and sometimes the load area or blind spots.

The immediate return is on claims. In a disputed collision, footage establishes fault in minutes rather than through weeks of argument, and fleets typically find the reduction in wrongly-attributed liability pays for the hardware faster than any safety benefit does.

The operational constraint is retrieval. Continuous footage cannot be uploaded over cellular — the data volume is prohibitive — so footage stays on the device and only event clips are pulled. That makes trigger configuration and storage retention the decisions that determine whether the right footage still exists when it is needed, which is often weeks later.
