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.
