Abstract
Audio/video (A/V) recording and communication devices according to the present embodiments comprise a processor, a motion sensor, and a camera. In various embodiments, the A/V recording and communication devices are configured to reduce latency and/or to reduce false positive indications of motion.
Claims18
A method for an audio/video (A/V) recording and communication device, the A/V recording and communication device including a processor, a motion sensor, and a camera, the method comprising:
- the motion sensor gathering information from within a field of view of the motion sensor and generating an output signal;
- at a beginning of a sampling interval, the processor transitioning from a low-power state to an active state;
- in response to transitioning to the active state, the processor analyzing the output signal that is generated by the motion sensor during the sampling interval to determine whether motion is indicated within the field of view of the motion sensor;
- at an end of the sampling interval, the processor transitioning from the active state to the low-power state;
- and
- when motion is indicated within the field of view of the motion sensor, then powering up the camera of the A/V recording and communication device.
An audio/video (A/V) recording and communication device, comprising:
- a processor;
- a motion sensor configured to gather information from within a field of view of the motion sensor and to generate an output signal based on the gathered information;
- a camera;
- and
- memory storing instructions that, when executed by the processor, cause the processor to:
- at a beginning of a sampling interval, transition from a low-power state to an active state;
- during the sampling interval, analyze the output signal that is generated by the motion sensor during the sampling interval to determine whether motion is indicated in the field of view of the motion sensor;
- upon determining that motion is not indicated in the field of view of the motion sensor, revert to the low-power state from the active state;
- and
- upon determining that motion is indicated in the field of view of the motion sensor, power up the camera of the A/V recording and communication device.
An audio/video (A/V) recording and communication device, comprising:
- a processor;
- a motion sensor configured to gather information from within a field of view of the motion sensor and to generate an output signal based on the gathered information;
- a camera;
- and
- memory storing instructions that, when executed by the processor, cause the processor to:
- transition, at a beginning of a sampling interval, from a low-power state to an active state without receiving an interrupt signal from the motion sensor;
- sample the output signal from the motion sensor that is generated during the sampling interval;
- analyze the sampled output signal to determine whether motion is indicated within the field of view of the motion sensor during the sampling interval;
- if no motion is indicated within the field of view of the motion sensor, then revert to the low-power state;
- and
- if motion is indicated within the field of view of the motion sensor, then power up the camera of the A/V recording and communication device.
