Abstract

A system for event recording includes an interface and a processor. The interface is configured to receive video data and sensor data. The processor is configured to determine a risk level based at least in part on the sensor data; determine a storage quality based at least in part on the risk level; determine a processed video data by processing the video data according to the storage quality; and store the processed video data.

Claims

1. A system for event recording, comprising:

an interface configured to receive video data and sensor data; and

a processor configured to;

determine a risk level based at least in part on the sensor data;

determine a storage quality based at least in part on the risk level, wherein the storage quality includes one or more video properties;

process the video data according to the storage quality, wherein to process the video data according to the storage quality includes a step of adjusting at least one of the one or more video properties of the video data based on the determined storage quality; and

store the processed video data.

2. The system of claim 1, wherein the interface is further configured to receive a time.

3. The system of claim 2, wherein the risk level is based at least in part on the time.

4. The system of claim 1, wherein the interface is further configured to receive an amount of available storage.

5. The system of claim 4, wherein the storage quality is based at least in part on the amount of available storage.

6. The system of claim 1, wherein the interface is further configured to receive a traffic level.

7. The system of claim 1, wherein the processor is further configured to determine one or more anomalous events based at least in part on the sensor data.

8. The system of claim 7, wherein the risk level is based at least in part on the one or more anomalous events.

9. The system of claim 1, wherein the risk level is one of a plurality of risk levels.

10. The system of claim 1, wherein the risk level is determined during a time of low processor activity.

11. The system of claim 1, wherein the one or more video properties includes a frame rate.

12. The system of claim 1, wherein the one or more video properties includes a resolution.

13. The system of claim 1, wherein the one or more video properties includes a compression rate.

14. The system of claim 1, wherein the one or more video properties includes a data rate for compression.

15. The system of claim 1, wherein the processor is further configured to process the sensor data according to the storage quality.

16. The system of claim 15, wherein the processor is further configured to store the processed sensor data.

17. A method for event recording, comprising:

receiving video data and sensor data;

determining, using a processor, a risk level based at least in part on the sensor data;

determining a storage quality based at least in part on the risk level, wherein the storage quality includes one or more video properties;

processing the video data according to the storage quality, wherein processing the video data according to the storage quality includes adjusting at least one of the one or more video properties of the video data based on the determined storage quality; and

storing the processed video data.

18. A computer program product for event recording, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving video data and sensor data;

determining a risk level based at least in part on the sensor data;

determining a storage quality based at least in part on the risk level, wherein the storage quality includes one or more video properties;

processing the video data according to the storage quality, wherein processing the video data according to the storage quality includes adjusting at least one of the one or more video properties of the video data based on the determined storage quality; and

storing the processed video data.
