The proper positioning of your Video Doorbell Wired depends on a number of factors including the layout of your yard, the distance from the front door to the street, objects within the doorbell's field of view, height of the door and more.
Your Ring Video Doorbell Wired sees the world in two ways. First, the camera on your doorbell has a very wide view of the world as illustrated below:
One of the biggest mistakes people make is mounting their doorbell too high to view people's faces. In fact, as illustrated above, viewing faces is not a problem if the doorbell is mounted at the correct height, approximately 47-62 inches (1.2 meters, 3.39' - 5.24'). For Video doorbell Wired, mounting at the higher end of the range is optimal.
The second way your Video Doorbell Wired sees the world is through a network of PIR or "Passive Infrared" motion sensors. These are heat sensors that detect motion by monitoring heat within the detection area. Since people are hotter than the surrounding areas, as a person enters the detection area the heat measurements change. The motion sensors register this change as movement and send out an alert. As illustrated in the image below, the motion sensors have a much more focused field of view than the camera:
The motion sensors in your Video Doorbell Wired are designed to detect motion up to 155 degrees horizontally and from five to 25 feet outward from the fixture. They're also more sensitive to horizontal movement across the detection area than vertical. If you mount the doorbell too high, you're more likely to catch the heat of passing cars than the heat of incoming visitors.
Now that you understand how your Video Doorbell Wired sees the world, positioning it properly becomes much easier.
