Wearable recording system with memory designation
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.
1. A recording system for saving a sequence of clips comprising:
at least one memory communicatively coupled with a sensor; and
a computer processor configured to:
record sensor data obtained by the sensor in the at least one memory;
in response to a first trigger signal, designate for write-protecting a first portion of the sensor data that was captured prior to occurrence of the first trigger signal, wherein the first portion of the sensor data occupies a portion of the at least one memory that is less than the entirety of the at least one memory and corresponds to a length of time prior to the first trigger signal;
continuing to record the sensor data in the at least one memory while the first portion of the sensor data is designated for write-protecting;
in response to a subsequent second trigger signal, designate for write-protecting a second portion wherein the second portion occupies less than the remaining entirety of the at least one memory not designated for write-protecting and corresponds to a length of time prior to the second trigger signal; and
upon reaching at least one of the first portion and the second portion while continuing to record the sensor data in the at least one memory, excluding from overwriting the at least one of the first portion and second portion.
2. The recording system of claim 1 , further including with the first portion of the sensor data, another portion of the sensor data that was captured after occurrence of the first trigger signal.
3. The recording system of claim 2 , wherein the computer processor is further configured to, in response to an end signal, end the first portion of the sensor data captured after the occurrence of the first trigger signal that is designated as write-protected.
4. The recording system of claim 3 , where in the end signal comprises at least one of:
an expiration of a pre-defined length of time;
an audio command;
a stop button signal;
a stop switch signal; or
a recognized object within the sensor data.
5. The recording system of claim 1 , wherein the computer processor is further configured to transmit, via a wireless transmitter, the first portion of the sensor data to a remote memory.
6. The recording system of claim 1 , wherein the sensor data comprises at least one of the following: image data and video data.
7. The recording system of claim 1 , wherein a portion of the at least one memory comprises a circular buffer.
8. The recording system of claim 1 , wherein the first portion of the sensor data is stored using at least one of time compression or frame compression.
9. The recording system of claim 1 , further comprising a camera that includes the sensor, the at least one memory, and the computer processor.
10. The recording system of claim 9 , wherein the camera comprises a security camera.
11. The recording system of claim 1 , further comprising a cell phone including the sensor, the at least one memory, and the computer processor.
12. The recording system of claim 1 , further comprising a personal area network coupled with the computer processor and including at least two of the following: the sensor, the at least one memory, and the computer processor.
13. The recording system of claim 1 , wherein the at least one memory is configured to record the first portion of the sensor data in a file.
14. The recording system of claim 1 , wherein the first trigger signal represents detection of at least one of the following: a motion, a sound, an image, content in a data stream, a pattern in the sensor data, a person, a human face, a computer screen, an event, a verbal command, operation of switch, and operation of a button.
15. The recording system of claim 1 , wherein the computer processor is further configured to write-protect the first portion of the sensor data as a write-protected portion in the at least one memory.
16. The recording system of claim 15 , wherein the computer processor is further configured to free the write-protected portion following a transmission of the first designated portion.
17. The recording system of claim 1 , wherein the computer processor is further configured to index the first designated portion while the recording facility is still recording the sensor data into the at least one memory.
18. The recording system of claim 1 , wherein the computer processor is configured to record the sensor data continuously, from before the first trigger signal, through a pre-designated time period, and after the pre-designated time period.
19. The recording system of claim 1 , wherein the computer processor is configured to automatically overwrite portions of the sensor data that were recorded in the at least one memory that were not designated for saving.
20. A recording system for saving a sequence of clips comprising:
at least one memory communicatively coupled with a sensor; and
a computer processor configured to:
record sensor data obtained by the sensor in the at least one memory;
in response to a first trigger signal, write-protecting a first portion of the sensor data that was captured prior to occurrence of the first trigger signal, wherein the first portion of the sensor data occupies a portion of the at least one memory that is less than the entirety of the at least one memory and corresponds to a length of time prior to the first trigger signal;
continuing to record the sensor data in the at least one memory while the first portion of the sensor data is write-protected;
in response to a subsequent second trigger signal, write-protecting a second portion wherein the second portion occupies less than the remaining entirety of the at least one memory not write-protected and corresponds to a length of time prior to the second trigger signal; and
upon reaching the at least one of the first portion and the second portion while continuing to record the sensor data in the at least one memory, excluding from overwriting the at least one of the first portion and second portion.
