Abstract: A surveillance apparatus continuously records imaged data from a camera into a circular buffer in a local memory. When a record signal is received, the system records the video stream that was recorded before the record signal was received, and the video stream that is recorded after the record signal was received. The recorded segment is then write-protected, so that the surveillance apparatus does not overwrite the recorded segment. The recorded segment could then be sent to a remote memory via a wireless connection to free up local memory for future recording sessions.

Abstract: A methods in which a camera can store discrete segments of imaged data, using a sensor in the camera to capture image data, using multiple portions of a memory as a loop in which to record the segments in approximately real time, and protecting the multiple portions from being overwritten by subsequent recording in the loop. Recorder continues to record the image data immediately after ending at least one of the segments or immediately after protecting at least one of the segments. Protected data or segments can be wirelessly transmitting a first one of the segments to a memory, and releasing a corresponding one of the multiple portions of memory from protection. Recorder and signal switch are located or as part of an accessory, such as a pair of glasses.
