Video recorder
Methods and apparatuses are disclosed for recording video data of an event. The apparatuses include a processor communicating with memory. The memory stores video data of the event captured by a camera, and the video data includes a series of picture frames of the event. A loop buffer also stores video data of the event captured by the camera. A rule-based engine stored in the memory uses a set of rules to store the contents of the loop buffer in the memory. The apparatus utilizes the loop buffer to provide video data prior to occurrence of the event.
1. A system, comprising:
a processor;
a buffer in communication with the processor;
a camera configured to capture video data associated with a vehicle;
memory having program instructions stored therein that are executable by the processor to cause the system to perform operations including:
storing the video data in the buffer;
in response to a triggering event and communications between a vehicle controller computer and the camera:
transferring the stored video data from the buffer to a storage in the vehicle; and
tagging the stored video with metadata, wherein the vehicle controller computer implements logic to detect multiple types of triggering events corresponding to different scenarios and wherein the metadata indicates which type of triggering event caused the transferring;
wherein the vehicle controller computer controls performance of one or more components of the vehicle; and
an interface capable of transferring the video data from at least one of the camera, the buffer, or the storage to a portable device.
2. The system of claim 1 , wherein the metadata includes a description of the video data.
3. The system of claim 1 , wherein the metadata identifies an attempted access event associated with the vehicle.
4. The system of claim 1 , wherein the operations further include:
receiving vehicular data from one or more sensors within in the vehicle.
5. The system of claim 4 , wherein the vehicular data includes accelerometer data from an accelerometer installed in the vehicle.
6. The system of claim 5 , wherein the triggering event is an occurrence of the accelerometer data exceeding a threshold and indicating an excessive yaw, pitch, or roll movement of the vehicle.
7. The system of claim 4 , wherein the vehicular data includes data received from an ignition system of the vehicle.
8. The system of claim 4 , wherein the vehicular data includes data received from a throttle position sensor of the vehicle.
9. The system of claim 4 , wherein the vehicular data is used to detect one or more of an under or over voltage or current condition, an open circuit condition, a circuit failure, a power failure, or a battery failure.
10. The system of claim 1 , further comprising:
a switch operable by a user to trigger transferring the stored video data from the buffer to the storage in the vehicle.
11. The system of claim 1 , further comprising:
a microphone configured to capture audio data;
wherein the operations further include:
storing the audio data in the buffer; and
in response to the triggering event, transferring the stored audio from the buffer to the storage.
12. The system of claim 1 , wherein the storage includes a removable memory storage device.
13. The system of claim 1 , wherein the operations further include:
in response to the triggering event, transferring tagged video data via a wireless interface to a remote device.
14. A method, comprising:
storing, in a buffer of a system, video data captured by a camera associated with a vehicle;
collecting vehicular data from one or more sensors within in the vehicle;
in response to a triggering event indicated by the vehicular data and communications between a vehicle controller computer and the camera:
transferring the stored video data from the buffer to a storage in the vehicle; and
tagging the stored video with metadata indicative of the triggering event, wherein the vehicle controller computer implements logic to detect multiple types of triggering events corresponding to different scenarios, wherein the metadata indicates which type of triggering event caused the transferring, and wherein the vehicle controller computer controls performance of one or more components of the vehicle; and
transferring, in response to a user command, the video data from at least one of the camera, the buffer, or the storage to a portable device via an interface.
15. The method of claim 14 , wherein the metadata includes vehicular data received from one or more sensors in the vehicle and associated with the trigger event.
16. A non-transitory computer readable medium having program instructions stored therein that are executable by a system to cause the system to perform operations comprising:
storing, in a buffer of the system, video data captured by a camera associated with a vehicle;
detecting a triggering event based on one or more of a plurality of rules;
in response to the triggering event and communications between a vehicle controller computer and the camera:
transferring the video data from the buffer to a storage; and
tagging the transferred video with metadata that identifies the one or more rules wherein the vehicle controller computer implements logic to detect multiple types of triggering events corresponding to different scenarios and wherein the metadata indicates which type of triggering event caused the transferring;
wherein the vehicle controller computer controls performance of one or more components of the vehicle; and
transferring, in response to a user command, the video data from at least one of the camera, the buffer, or the storage to a portable device via an interface of the system.
17. The computer readable medium of claim 16 , wherein the operations further include:
receiving vehicular data from one or more sensors in the vehicle, wherein the plurality of rules includes a rule associated with the vehicular data.
18. The computer readable medium of claim 17 , wherein the one or more sensors includes an ignition system, an engine management system, a powertrain management system, or an electrical management system.
