For the eufyCam 3/3C system, the AI engine is built in S380 HomeBase, which supports Face Detection, Human Detection, Vehicle Detection, and Animal Detection.
 

The Face Detection feature can help to recognize the people that showing around the user's house, such as family members, friends, couriers, or others. You can set the Familiar Face and Stranger Face on the Face Management page.

The Human Detection feature can reduce the number of false alarms sent by filtering out events that don't include humans, such as the motions of cars and animals.

Here is an article about How does the Human Detection technology work? 
 

The Vehicle Detection feature can help to catch up with the user's vehicle in the backyard or driveway. It can only detect the running vehicle to reduce too many detections because of the parking vehicle. 
 

The Animal Detection feature can detect four-leg animals.

Note: Vehicle Detection and Animal Detection are still in beta mode. If there is any false detection please contact us and donate some recordings to help our team improve the AI feature.
