You can mount and aim the Arlo Ultra camera in different ways to optimize the camera’s ability to detect motion in specific areas. The lower two-thirds of the camera’s field of view is the motion-sensitive part of the image. Aim the camera so that any motion you wish to detect appears within this part of the image.
If you want to monitor motion closer to the camera, such as visitors to your front door, you can mount the camera at least 7 feet (2 meters) high and aim it so that visitors will appear in the lower two-thirds of the image. This angle works well to avoid motion alerts for movement in the top third of the image, such as vehicles driving by.
If you want to monitor motion occurring farther away, such as children playing on a lawn, aim the camera higher to frame the area within the lower two-thirds of the image.
It’s best to position the camera so that motion is moving from side-to-side across its field of view rather than directly toward or away from the camera. Also, though the camera can detect motion up to 25 feet (7.6 meters) away, the best area for motion detection is 5 to 20 feet (1.5 to 6 meters) from the camera position.
