Abstract: A wireless speaker device configured for use with a wireless A/V recording and communication device, such as a doorbell. The wireless speaker device, which includes a speaker, may connect to the user's local area network (LAN), such as a Wi-Fi network. The LAN is connected to a wide area network (WAN), such as the Internet and/or a public switched telephone network (PSTN). When the wireless A/V recording and communication device detects a visitor, it sends a first signal, via the LAN, to device backend server in the WAN. In response, the back-end server in the WAN transmits a second signal, via the LAN, to the wireless speaker device. The second signal to the wireless speaker device includes a command for the wireless speaker device to emit a tone through its speaker. The wireless speaker device then emits a tone through its speaker to alert the user that a visitor is at the wireless A/V recording and communication device.

Abstract: Techniques are disclosed to identify a previously-not-present stationary object within a sequence of image frames. A system determines a first frame of the plurality of image frames where an object is not within a field of view of the camera of the A/V device. The system then analyzes other frames to determine that the object becomes present and is stationary within the field of view of the camera. The system may identify a person approaching and moving away from the A/V device. The system may identify a stationary vehicle within and subsequently not within the field of view of the camera. The system may use identification of the parcel to generate a control signal that changes the operational mode of the A/V device to parcel protect mode.

Abstract: Parcel theft deterrence for audio/video (A/V) recording and communication devices, such as video doorbells and security cameras. When an A/V recording and communication device captures image data that includes a parcel, a parcel boundary may be created for monitoring the parcel within. In various embodiments, when the parcel is removed from the parcel boundary, a user alert may be generated to notify a user of a client device associated with the A/V recording and communication device that the parcel has been removed.

Abstract: Techniques are disclosed to detect and/or deter parcel theft based at least in part on predicted parcel delivery times. In various embodiments, a predicted delivery time at which a parcel is expected to be delivered to an associated delivery address is determined based at least in part on delivery schedule information. An audio/video recording and communication device installed at the delivery address is operated in a parcel protect mode in which the audio/video recording and communication device is configured to be used to detect one or both of delivery of the parcel to the delivery address and removal of the parcel from the delivery address.

Abstract: In a battery-powered audio/video recording and communication device having a camera, the length of a preset interval (the interval between instances of the device sending a request to a network to check whether any user requests to access the camera have been received) may be adjusted upward or downward in order to balance the competing interests of reducing latency (e.g. reducing the delay that the user may experience when trying to access the camera) and conserving battery life. The present embodiments advantageously balance these competing interests by initially setting the length of the preset interval to be relatively short to reduce latency, but automatically increasing the length of the preset interval as the battery charge is depleted, thereby extending battery life. The present embodiments also advantageously enable the length of the preset interval to be increased after the battery is recharged, thereby reducing latency.

Abstract: In an A/V recording and communication device, the power configuration of the device is considered when determining a setting for a keep-alive interval of the device. If the device is connected to a reliable and continuous source of power, such as AC mains, then the keep-alive interval may be set to a very short duration, thereby reducing or eliminating any latency that the user might experience when attempting to remotely access the camera of the device. By contrast, if the device relies solely on a rechargeable battery for power, then the keep-alive interval may be set to a longer duration, thereby reducing the rate at which the rechargeable battery will be discharged. And, if the device is connected to an intermittent source of power, such as a solar panel, then the keep-alive interval may be set to a moderate duration to balance the competing interests of reducing latency and conserving battery life.

The signal to the wireless speaker device includes a command for the wireless speaker device to emit a tone through its speaker.

Abstract: Methods for audio/video (A/V) recording and communication devices including a camera, are provided. One such method comprises determining that a parcel has been left within an area about the A/V recording and communication device, determining that the parcel has been removed from the area about the A/V recording and communication device, determining whether removal of the parcel from the area about the A/V recording and communication device was authorized, and when the removal of the parcel from the area about the A/V recording and communication device is determined to have been unauthorized, generating an alert.

Abstract: Video footage captured by A/V recording and communication devices may be readily uploaded to the cloud and shared with a requesting party, such as a law enforcement agency. When a request is received from a requesting party for video footage, a set of videos meeting the criteria specified by the requesting party may be determined. Consent requests may then be sent to users associated with each of the A/V recording and communication devices that recorded the videos meeting the criteria specified by the requesting party. When user consents to share the videos are received, the video footage may be provided to the requesting party.
