In the modern era of automotive technology, your vehicle is a silent witness that records the seconds leading up to and following a collision. Digital evidence, specifically from dashcams and Event Data Recorders (EDRs), is arguably the most objective account of an accident. However, unlike physical debris at a scene, digital data is incredibly perishable. If you do not act with precision in the minutes following an accident, that evidence can be permanently lost or overwritten.

Understanding the Difference: Dashcams vs. EDRs

To protect your evidence, you must first understand the distinction between your two main sources of data:

• The Dashcam: A consumer-grade device—usually mounted to the windshield—that records audio, video, and sometimes GPS data. Most dashcams operate on a “loop recording” cycle. Once the memory card reaches capacity, the device automatically begins overwriting the oldest footage with new data.
• The Event Data Recorder (EDR): Often referred to as a
