Abstract:
1. A surveillance apparatus, comprising: a camera having an image capturing component that captures images, and a converting component that converts the images into at least one data stream; a local memory functionally coupled to the camera; a wireless transmitter functionally coupled to the local memory; a recording facility that continuously records the data stream into available portions of a circular buffer in the local memory as a first file using a digital video file format; a protecting facility that responds to a signal to record by designating a segment of the circular buffer as a write-protected portion and by indexing the write-protected portion as a second distinct file in the circular buffer, wherein the segment includes a pre-recorded subset recorded before the signal is received and a post-recorded subset to be recorded after the signal is received; and a sending facility that uses the transmitter to wirelessly transmit the second file to a remote memory.
