1. A surveillance apparatus, comprising:
- a camera having an image capturing component that captures image data;
a local memory functionally coupled to the camera;
a recording facility that records the image data 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 the image data by designating a segment of the circular buffer as a write-protected portion and by indexing the write-protected portion as a second 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
wherein the local memory is configured to allow access to at least one of the files.

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.

12. A method of processing imaged data from a camera, comprising the following steps:
-
receiving video data; recording the video data into available portions of a circular buffer as a first file; responding to a signal by write-protecting a segment that includes a newly recorded portion of the buffer, wherein the newly recorded portion is recorded before the signal is received, and includes a post-recorded portion to be recorded after the signal is received; indexing write protected portions of the buffer as separate, distinct files during the step of recording; and allowing access to at least one of the distinct files from the write-protected portions of the circular buffer. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
