You can use Arlo Go camera skins in a wide variety of weather conditions, including direct sunlight. However, if you keep an Arlo Go camera in direct sunlight while it has a camera skin on it, the camera might shut down when the ambient temperature reaches 104°F (40°C).
If the Arlo Go shuts down, bring it to a cooler location that is not in direct sunlight. The camera resumes operation as soon as it reaches a safe temperature.
