## 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.

## Claims

### Claim 1

A non-transitory machine-readable medium of an audio/video recording and communication device (A/V device) storing a program for providing remote access to a camera of the A/V device, the program executable by a processor of the A/V device, the program comprising instructions for:
periodically transitioning the processor from a low-power state to an active state;
transmitting a data request to a network device to determine whether a user has requested remote access to the camera of the A/V device;
receiving a return signal from the network device comprising at least one of a positive response and a negative response; and
transitioning the processor from the active state to the low-power state when the return signal from the network device is the negative response; or
capturing image data using the camera when the return signal from the network device is the positive response.

### Claim 2 (depends on 1)

The non-transitory machine-readable medium of claim 1, wherein the program comprises further instructions for periodically transitioning the processor from the low-power state to the active state according to a preset interval.

### Claim 3 (depends on 2)

The non-transitory machine-readable medium of claim 2, wherein the preset interval is set to an initial value.

### Claim 4 (depends on 3)

The non-transitory machine-readable medium of claim 3, wherein the initial value is 10 seconds.

### Claim 5 (depends on 3)

The non-transitory machine-readable medium of claim 3, wherein the preset interval is adjusted based on a battery charge level of the A/V device.

### Claim 6 (depends on 5)

The non-transitory machine-readable medium of claim 5, wherein the preset interval is increased as the battery charge level of the A/V device decreases.

### Claim 7 (depends on 5)

The non-transitory machine-readable medium of claim 5, wherein the preset interval is decreased as the battery charge level of the A/V device increases.

### Claim 8 (depends on 3)

The non-transitory machine-readable medium of claim 3, wherein the program comprises further instructions for receiving, from the network device, a command to set the preset interval to the initial value.

### Claim 9 (depends on 3)
