Abstract

Computer-implemented methods and systems for processing recorded data for storage is provided. An auditable device, such as a digital video camera, stores a set of recorded data. The auditable device also stores auditable event entries that represent auditable events detected by the auditable device. One type of auditable event is the receipt of information from a computer-aided dispatch (CAD) system that indicates an event. The auditable device marks at least one subset of the set of recorded data based on the auditable event entries, and uploads the marked at least one subset of the set of recorded data to an evidence management system.

Claims

1. A computer-implemented method of processing recorded data for storage, the method performed by an auditable device, the method comprising:

storing a set of recorded data within a data store of the auditable device;

receiving information from a computer-aided dispatch system indicating at least one event, the at least one event includes an event start time and an event stop time;

marking at least one subset of the set of recorded data based on the at least one event received from the computer-aided dispatch system; and

uploading the marked at least one subset of the set of recorded data to an evidence management system, the marked at least one subset of the set of recorded data is less than all of the set of recorded data.

2. The method of claim 1 further comprising:

preserving the set of recorded data in the data store of the auditable device until an acknowledgement is received by the auditable device from the evidence management system that all marked subsets of the set of recorded data have been stored by the evidence management system; and

deleting, by the auditable device, the set of recorded data from the data store of the auditable device in response to receiving the acknowledgement.

3. The method of claim 1 wherein the information from the computer-aided dispatch system is received by the auditable device via a physical dock interface of the auditable device.

4. The method of claim 1 wherein the information from the computer-aided dispatch system is received by the auditable device via a long-range wireless interface of the auditable device.

5. The method of claim 1 wherein the information from the computer-aided dispatch system is received by the auditable device via a connection to a coordinator computing device over a short-range wireless interface of the auditable device.

6. The method of claim 1 wherein marking the at least one subset of the set of recorded data based on the at least one event received from the computer-aided dispatch system includes creating, by the auditable device, at least one auditable event entry for the at least one event received from the computer-aided dispatch system in an audit trail data store of the auditable device.

7. The method of claim 6 wherein creating at least one auditable event entry for the at least one event received from the computer-aided dispatch system comprises:

creating an event start auditable event entry based on the event start time received from the computer-aided dispatch system and creating an event end auditable event entry based on the event stop time received from the computer-aided dispatch system.

8. The method of claim 7 wherein creating an event start auditable event entry based on the event start time received from the computer-aided dispatch system includes creating an event start auditable event entry that indicates a time that is a predetermined amount of time before the event start time received from the computer-aided dispatch system.

9. The method of claim 6 further comprising:

receiving, by the auditable device, at least one signal from a source other than the computer-aided dispatch system that indicates an auditable event, and

storing, by the auditable device, at least one additional auditable event entry in the audit trail data store of the auditable device based on the at least one signal.

10. The method of claim 1 wherein:

the auditable device is an auditable camera; and

the set of recorded data includes video data.

11. An auditable camera, comprising:

a video sensor;

a video data store configured to store video data generated by the video sensor;

an audit trail data store configured to store a set of auditable event entries; and

an audit trail gathering engine wherein;

in response to receiving a notification of an event reported by a component of the auditable camera, the audit trail gathering engine records an auditable event entry representing the event in the audit trail data store;

the auditable camera transmits a subset of the video data stored in the video data store to an evidence management server, the subset of the video data is selected based on the auditable event entry.

12. The auditable camera of claim 11 wherein the event reported by the component of the auditable camera is a receipt of information generated by a computer-aided dispatch system indicating at least an event start time.

13. The auditable camera of claim 12 further comprising a short range wireless interface, and wherein the information generated by the computer-aided dispatch system is received by the auditable camera from a coordinator computing device via the short range wireless interface.

14. The auditable camera of claim 12 further comprising a long range wireless interface, wherein the information generated by the computer-aided dispatch system is received by the auditable camera from the computer-aided dispatch system via the long range wireless interface.

15. The auditable camera of claim 12 further comprising a physical dock interface, wherein the information generated by the computer-aided dispatch system is received by the auditable camera via the physical dock interface.

16. The auditable camera of claim 15 wherein the auditable camera is configured to transmit the subset of the video data from the video data store to the evidence management server via the physical dock interface.

17. The auditable camera of claim 11 wherein the event reported by the component of the auditable camera is a receipt of event start information entered by a user associated with the auditable camera.

18. The auditable camera of claim 11 further comprising at least one physical user interface device, wherein the event reported by a component of the auditable camera represents an interaction with the physical user interface device.

19. The auditable camera of claim 11 wherein the auditable camera is configured to at least begin storing the video data generated by the video sensor in the video data store before the notification of the event is received by the audit trail gathering engine.

20. A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors of an auditable device, cause the auditable device to perform actions for processing recorded data for storage, the actions comprising:

storing a set of recorded data within a data store of the auditable device;

receiving information from a computer-aided dispatch system indicating at least one event, the at least one event includes an event start time and an event stop time;

marking at least one subset of the set of recorded data based on the at least one event received from the computer-aided dispatch system; and

uploading the marked at least one subset of the set of recorded data to an evidence management system, the marked at least one subset of the set of recorded data is less than all of the set of recorded data.
