High resolution pre-event record
First Claim
1. A mobile digital video recording surveillance system installed within a public transport vehicle comprising:
- a plurality of data capture devices for continuously capturing video, audio, and meta-data comprising at least two separate data streams;
a memory device including a permanent memory area and a memory buffer to permanently store a first one of said captured data streams in said permanent memory area and temporarily store a second one of said captured data streams in said memory buffer;
a trigger device to monitor the operational environment for pre-configured trigger event conditions;
a logic device pre-configured to switch recording from a first data stream to a second data stream and directing said second data stream to said permanent memory area in the presence of a trigger event;
a timer set for a pre-configured duration which is initiated upon reception of a trigger event;
wherein the system continues to capture and record said second data stream during the duration of said timer and, at the termination of said timer duration, switches said second data stream recording to said memory buffer and resumes recording said first data stream to said permanent memory area.

Abstract
The High Resolution Pre-Event Record system is an innovative means for collecting audio, video, and meta-data in a mobile vehicle platform and continuously recording this information stream to a high-capacity storage device at different levels of data resolution based upon the status of a trigger event. The occurrence of a trigger event will cause the system to store higher resolution data to an on-board high-capacity storage device prepended by a configurable amount of high resolution data previously recorded into a pre-event data buffer. The data stream may later be downloaded to an external storage device for future review and analysis.

8. A process for initiating a mobile digital video recording surveillance system installed within a public transport vehicle to record a preferred data stream comprising:
-
continuously capturing video, audio, and meta-data comprising at least two separate data streams;
initiating a permanent memory area and a memory buffer to permanently store a first one of said captured data streams in said permanent memory area and temporarily store a second one of said captured data streams in said memory buffer;
monitoring the operational environment for pre-configured trigger event conditions;
directing said second data stream to said permanent memory area in the presence of a trigger event;
setting a timer for a pre-configured duration which is initiated upon reception of a trigger event;
wherein the system continues to capture and record said second data stream during the duration of said timer and, at the termination of said timer duration, switches said second data stream recording to said memory buffer and resumes recording said first data stream to said permanent memory area. - View Dependent Claims (9, 10, 11, 12, 13, 14)
