If you have a narrow door frame or awkward install location, a wedge kit can be perfect to help get the best video capture possible. The Nest Hello comes with a 15° wedge included in the box, allowing you to slightly tilt your camera angle to either the left or the right (just flip the wedge upside down to tilt the either direction). Unfortunately 15° is not a huge tilt - if the walkway to your front door is at a right angled, for example, then a 45° wedge kit should be used instead. Some people have spoken to Nest support about this issue and Nest have sent out further wedge kits, which can then be stacked together (with glue) to achieve 30° or 45° viewing angles instead. Alternatively, now that the Hello has been out for a couple of years, you can buy third party wedge kits from Amazon which work well. Finally, it's worth pointing out that the wedge kit allows you to turn the video left or right. It won't work with 'up to down' angles. Again, a third party wedge kit can help with this instead.
