Important: Most battery cameras have a white light/spotlight. However, for a few battery cameras, they don't have a white light/spotlight. Neither do the plug-in cameras.
You can tap the camera "setting" icon > tap "Lighting Setting" > enable "Flashlight Alarm". After that, the white light/spotlight will be flashing for a while once the camera is triggered by any movements. Of course, if there is no "Flashlight Alarm" option under the "Lighting Setting" page, that means that your camera does not support a white light/spotlight.
However, if you want the camera's white light/spotlight to be on constantly in the dark or at night, you can turn off "Flashlight Alarm" and set "Night Vision Mode" as "White light mode" instead.
