Controlling a Nest Cam with a battery by voice means asking a Google Assistant speaker or display to show it, since the camera has no speaker for commands of its own, and when it fails, the cause is usually the link between the camera, the Google Home app and the display. Say the camera's name, as it appears in the app, such as show the porch camera on the living room display, and the display should open the live view.
The checks in more detail
Check the name: a camera named something awkward, or two cameras with similar names, confuses the assistant, so rename it in the Google Home app to a short, clear name. Check that the camera and the display are in the same home and that the display is signed in to the same Google account. The display must be a Google Nest Hub, a Nest Hub Max or another display that supports the camera feeds, or a Chromecast with Google TV or a TV with Google TV; a speaker without a screen can only announce events and cannot show video.
Make sure that the camera's live view works in the app first, since the display uses the same stream: if the app cannot show live view, fix the camera's Wi-Fi first. A battery camera sleeps to save power, and live view can take a few seconds to wake it; allow time before repeating the command. Check that your account has the right permissions and that, if you have a subscription for event history, it is active, though live view does not need one. Voice commands that stop working after an update can be repaired by unlinking and relinking, or by restarting the display.
Check that the Google Assistant and the voice match are on, in the Google Home app, because a display set to guest mode may refuse. In the app, check that the camera is in the room you mention. For alerts spoken by a speaker, such as announcing a person at the door, turn on the notification announcements in the speaker's settings. If a command works on the phone but not on the display, the display is the issue; restart it. If the camera appears offline, charge it and check its signal. Contact Google support if none of this helps.
