Advantages of face recognition in smart home security

With the appearance of face recognition technology, it is easier to verify a person's identity than before. Face recognition can be applied in many fields, one of which is smart home security system. When a known face is captured in the database, the security camera will recognize your friends and family and will not give an alarm. Otherwise, you'll get an immediate alert so you know that someone unknown has broken into your property. Sounds like a future security option? No more.

What is face recognition and how does it work?

Face recognition is a kind of biometric technology, it is not only to detect the face in the image or video. It will go a step further to determine whose face it is. The working principle of the face recognition system is to obtain a face image and predict whether the face matches another face stored in the database (or whether the face in one image matches the face in another image). Therefore, the technique aims to compare and accurately predict the potential match of the captured face, regardless of facial expression, age or facial hair.

How is face recognition applied in smart home security?

If you're going to make your house "smart," then safety should be your starting point. In any case, all your most precious valuables live here, and protecting them should be the top priority. Smart home security system can help you monitor your house at any time when you go out, away from the convenience of laptop or smart phone.

Traditionally, security providers send a technician to install a wired system in your home and register professional monitoring services for you. The story has changed. With the advent of intelligent technology, you can even set up your own intelligent system. In addition, you can act as a professional monitor for real-time updates and notifications on smart devices.

Face recognition means that the smart camera you use at home can connect a face with an identity. Therefore, for face recognition to work, you need to tell the system which face belongs to which name. This means that to apply facial recognition in a family safety system, you need to create profiles for friends, relatives, and other people you want the system to recognize. Then you can know when they are at your door and when they will come in.

Interestingly, through face recognition, you can also set the alarm criteria. For example, you can set an alert to notify you when someone's face is trying to enter your home without recognition.

Intelligent technology continues to develop rapidly. The company is now offering smart door locks with face recognition. Smart door lock with face recognition function, you only need to smile to open the door. However, you can lock and unlock smart doors in other ways, including PIN codes, and sometimes even physical keys. You can also set the smart door lock so that the system will send you an emergency alarm when someone on the blacklist tries to open the smart door lock.

What are the benefits of using face recognition in smart home security?

High accuracy rate

Most of the facial recognition software used in smart home locks can accurately determine whether the person attempting to enter the home matches the database of the person authorized to enter. In other words, some software programs are more accurate than others, especially in detecting faces from different perspectives and recognizing faces of different nationalities.

For those worried about accuracy, it should be noted that some software comes with the option of setting a custom confidence threshold, which can greatly reduce the possibility of the system returning false positives. You can also choose to use two factor authentication, such as face recognition combined with pin code or key fob.


Once you set up the smart home security system and allow the people you allow to enter your home, the system will automatically let these people enter when a match is detected. You don't need to ring the doorbell or respond to an entry request.

Intelligent integration

Using SDK or API, face recognition tools can be easily integrated into existing systems.

Why face recognition is better than other biometric verification solutions in the context of family safety. Biometric verification is based on unique behavioral and physiological features, including fingerprints, keystroke dynamics, facial features, gait and voiceprint. Face recognition has become the most popular because of its accuracy, ease of use and no touch.

Face recognition technology will continue to exist and will only get better over time. Intelligent technology changed the story
