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.

Abstract: Streaming and storing video for audio/video (A/V) recording and communication devices in accordance with various embodiments of the present disclosure are provided. In one embodiment, a method for an A/V recording and communication device comprises: recording video image data; executing a write operation to write the video image data at a write rate; executing a read operation to read the video image data at a first read rate that is greater than the write rate; continuing to read the video image data at the first read rate until the read operation catches up to the write operation; reading the video image data at a second read rate equal to the write rate; and transmitting streaming video to a client device, wherein a beginning portion of the streaming video is streamed at a first stream rate and thereafter streaming at a second stream rate less than the first stream rate.

Abstract: The present embodiments solve the problem of low-quality stored footage from video stream by storing copies of data packets at a local storage device of the A/V recording and communication device. The locally stored data is subsequently (e.g., after the live stream has terminated) uploaded to a remote storage device. If any data packets are lost during the upload process, those lost data packets can be re-sent from the local storage device to the remote storage device so that the complete recording can be stored at the remote storage device. The subsequent upload process may, in some embodiments, comprise a reliable data transfer protocol.

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: 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: 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: 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 signal, via the LAN, to at least one device in the WAN, such as a server and/or a service. In response, the at least one device in the WAN sends a signal, via the LAN, to the wireless speaker device. The 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.
