A tall frame that shows visitors head to toe
The 2560 × 1920 resolution has a 4:3 aspect ratio, taller than a usual widescreen picture, so the frame takes in both the face of the person at the door and a parcel left on the step. The 1.18 mm lens has a very short focal length, which makes it wide-angle, so the doorbell sees a broad area in front of the door. The F1.8 aperture helps at dusk, and the 10000 mAh battery means the doorbell does not have to be connected to mains power.
