Event data recorders are typically electronic devices that store information received from sensors connected to the device. An event data recorder is often referred to as a “black box,” a familiar recording device found on many large passenger aircrafts.

Event data recorders are now being designed into many other products to aid in diagnosing problems that may arise with usage of the given product. Automobiles, electronic panels, alarm systems, and some appliances are examples of products that can be equipped with event data recorders.

When a loss occurs, it is becoming more likely that some evidentiary information concerning the loss will be recorded onto some device. Typical recorded data may be the time a heat sensor activated in a fire alarm panel, the number of loads handled by a clothes dryer, or the speed of an automobile prior to a collision.
