What is Facial Recognition ?
Video Doorbell Dual can detect familiar faces when someone approaches or rings the doorbell. Our AI technology gets to work and sends you a notification so you can say “hello.”
Note: Facial Recognition is undergoing beta testing. We welcome your feedback to improve this feature. Scroll to the bottom of this article to find ways you can contact us.
How to Optimize Facial Recognition
1.Install the doorbell where there’s good daylight, and it’s directly in front of approaching visitors.
2.You’ll notice higher recognition rates if you have a wide porch (10 ft / 3 m or more) or your visitor looks right at the doorbell.
When Does Facial Recognition Work Best
A. Coming Home : When your visitor approaches with his or her head up and forward, he or she will most likely be recognized around 7-10 ft (2-3 m) away as long as he or she is walking directly in front of the doorbell.
B. Familiar Faces : People programmed as a Familiar Face will more likely be recognized.
Let’s Explain the Technology
We’re able to see wider angles at further distances, just like your doorbell. And like our eyes, your doorbell doesn’t have as wide of a field of view when objects come close.
Facial recognition is a bit different though. Unlike a V-shaped detection, this detection looks more like a house. So, if someone approaches too far to the left or right of your door, they won’t get detected.
And if you like numbers, here are some stats:
- Widest Detection Angle - Starts at 7 ft ( 2m)
- Horizontal Detection Distance - Max 2 ft (0.7 m)
- Likely Detection Range - Between 7-10 ft (2-3 m)
What Affects Facial Recognition
Technology
Video Doorbell Dual uses machine learning to ensure notifications are as accurate as possible, but the technology isn’t always perfect. We’re continuing to improve our technology. Help us improve by uploading your pictures and videos.
Installation Position
We recommended installing the doorbell at a height of 4 ft (1.2 m) above the ground. When a person stands in front of the doorbell, their face should be in the middle of the frame. Doorbells mounted on the side wall will not be able to recognize faces.
Lighting Conditions
A. Backlighting
This can happen during the day or at night and can reduce the accuracy of facial recognition.
B. Weak Lighting
Cloudy days or insufficient lighting at night may not produce enough illumination for Facial Recognition to work.
C. Recommendation
Purchase a smart fill light to help better illuminate faces in both scenarios.
Human Behavior
A. Walking Path
As mentioned previously, your visitor will be recognized if he or she looks directly at the doorbell while approaching for at least 1-2 seconds. People who are further than 10 ft (3 m) away or less than 2 ft (0.5 m) away will not be recognized.
B. Walking Speed
If a visitor walks toward your door at a speed greater than 3 mph (5 kph), Facial Recognition accuracy will decline.
Accessories
Facial Recognition does not work for people wearing masks, sunglasses, or other accessories. For people who wear glasses, the recognition rate will also decline.
Low-Quality Reference Pictures
For the best experience, upload high-resolution images of you and your loved ones’ faces to the eufy Security app. It’s best if the picture has nothing in front of the face. In addition, upload pictures without glasses, hats, motion blur, or nighttime black and white photos.
Smudged Camera Lens
Facial Recognition accuracy falls if your lens becomes dirty or foggy. You can wipe the camera with a clean, lint-free cloth to improve the detection rate.
Improve This Feature
If you’re not satisfied with Facial Recognition, tell us. We want to improve, and you can help. Share a video or picture of a face that wasn’t recognized, and we’ll use your data to help train our AI to do better. You can use the eufy Security app or contact us at support@eufylife.com. With your help, we can ensure Facial Recognition works 100% of the time for you.
