Your Arlo camera has a 110-degreeviewing angle. Position your camera so that the space that you want to monitor is within the camera&#039;s field of view. <span class="a-text-bold">Elevate your camera</span>. Mount your Arlo motion-detection camera at least 7 feet (2.1 meters) above the floor and aim it slightly downward for the best sensor performance. <span class="a-text-bold">Ensure that side-to-side traffic crosses Arlo&#039;s field of view</span>. Arlo&#039;s motion sensor is much more sensitive to side-to-side movement across its field of view than to movement directly toward or away from the camera. The best area for motion detection is 5 feet to 20 feet (1.5 to 6 meters) from the camera position.
