Abstract: A system for documenting events is provided. The system includes a camera for acquiring images and producing a video signal, a memory for storing images based on the video signal, and a sensor coupled to the memory. The memory includes a first volatile memory and a second non-volatile memory. The images are stored in the volatile memory, and the sensor actives a transfer of the images from the volatile memory to the non-volatile memory. In a preferred embodiment, before activating the transfer of the images from the volatile memory to the non-volatile memory, the sensor waits a preset time in order to acquire further images in the volatile memory. Also provided is a method for documenting events.
