Abstract
A video recording camera system configured to record video to a non-volatile memory configured as a circular video recording buffer. In an embodiment, the video recording camera system includes a non-volatile storage medium and a processor is configured to manage at least a portion of the non-volatile storage medium as a circular buffer, replacing recorded video data stored in a subset of memory addresses corresponding to an older recorded video frame with the data corresponding to a newer video frame. In further embodiments, clip files may be partitioned from the circular buffer to prevent logical portion of the recorded video from being overwritten upon reaching a capacity of the circular recorded video buffer.
