If you're installing a Ring Video Doorbell on a house with aluminum siding or on a house where the door is at the top of a set of stairs, you can use a wedge kit to properly position the device. This will help catch visitor motion, but minimize "false positive" motion alerts, such as cars on the street.
Both of these situations require the use of a wedge kit to properly angle your Ring Video Doorbell to catch the motions you want while avoiding the motions you don't.
Solar chargers, wedge kits, and corner kits
Solar chargers can be used with a wedge kit or a corner kit. However, only one wedge, or one corner mount is recommended. Stacking more than one wedge or corner mount changes the angle of the doorbell and can cast a shadow on the solar charger, making it less effective. Solar chargers should have direct sunlight for optimal performance.
There is also a Corner Kit for the Ring Video Doorbell. You can see the Corner Kit here.
Your Ring Video Doorbell first "sees" the world through a camera with a very wide view of the world as illustrated below:
Secondly, through a network of "PIR" or passive infrared sensors that the Ring Doorbell uses for motion detection. In the illustration below, you can see that the motion sensors have a much more focused field-of-view than the camera. Additionally, the view is pointed downward to catch motion within five to 30 feet of the Ring Doorbell--excluding motion sources outside that range.
Dealing with siding
If your house has siding, you'll need to take the angle of the siding into account when mounting your Ring Video Doorbell. As illustrated below, mounting the Ring Video Doorbell on siding will point the Ring Video Doorbell up, making it more likely to catch passing traffic than the heat of visitors.
If you mount your Ring Video Doorbell on siding, a wedge kit will properly angle your Ring Doorbell.
Dealing with Stairs
If your door is above ground level with stairs leading up to it, this can cause your Ring Video Doorbell to miss visitors walking up your stairs. It can also cause you to get motion alerts from passing traffic.
The solution in this case is to use a wedge kit to lower the angle of your Ring Video Doorbell.
Please note that wedge kits are paintable to match your house color.
