How to enable and adjust the motion sensor range?

Go to the Hi) Settings 
- Click on "motion sensor range" and increase or decrease the sensitivity using the + and - buttons If you live in the countryside, you can opt for high sensitivity, but if you live in the city, it is better to reduce the sensitivity to detect only the presence of  standing people in front of your door ... not to receive notifications for each passage of a car or person.
- In addition, check the box "detect fast motion" if you want to be notified of movements in front of your door even fast. Be careful this setting is much more sensitive and can detect sudden changes of light. The many false detection (passage of cars night, ect) and therefore notification of photos can increase significantly.
