Advantages Face Recognition in Smart Home Security
With the advent of face recognition, it’s now easier than before to verify the identity of a person. Facial recognition can be applied in many fields, one being smart home security systems. With known faces captured in a database, the security cameras will identify your friends and family members and won’t give an alarm. Otherwise, you’ll get an instant alert, so you know that someone unidentified has intruded into your property. Sounds like a futuristic security option? Not anymore.
What is facial recognition, and how does it work?
Facial recognition is a biometric technology that goes beyond just detecting human faces in an image or video. It goes a bit further to determine whose face it is. A facial recognition system works by taking an image of a face and predicting whether the face matches another face stored in a database (or whether a face in one image matches a face in another). Therefore, the technology is designed to compare and accurately predict potential matches of the face captured irrespective of facial expression, age, or facial hair.
How is face recognition applied in smart home security?
If you’re planning to make anything “smart” about your house, then security should be where you start. In any case, all your most precious valuables live here, and protecting them should be a top priority. A smart home security system helps you to keep tabs on your house while you’re away, from the convenience of your laptop or smartphone.
Traditionally, a security provider would send a technician to install a wired system in your home and enroll you in a professional monitoring service. The story has changed. With the advent of smart technology, you can even set up the smart system on your own. On top of that, you serve as the professional monitor, getting real-time updates and notifications on your smart device.
Facial recognition means that the smart camera you use in the home can associate a face with an identity. Therefore, for facial recognition to work, you’ll need to tell the system which face belongs to which name. That means that to apply facial recognition in home security systems, you’ll need to create profiles for friends, relatives, and others you want the system to identify. You’ll then be able to know when they are at your door or going into the house.
Interestingly, with facial recognition, you can also set select alarm criteria. For example, you can set alerts that notify you when somebody whose face the camera doesn’t recognize attempts to enter your home.
Smart technology has continued to grow in leaps and bounds. Companies are now starting to offer smart door locks with facial recognition. With a smart door lock with facial recognition, you can unlock your doors with nothing but a smile. You can, however, lock and unlock that smart door using other ways, including a pin code or sometimes even a physical key. You can also set up your smart home lock in such a way that if a blacklisted person attempts to open your smart door lock, the system will send you an emergency alert.
What are the benefits of using face recognition in smart home security?
High accuracy rates
Most facial recognition software being used in smart home locks can accurately determine whether the person trying to gain access to a home matches the database of people who have been authorized to enter. That said, some software programs are more accurate than others, especially when it comes to detecting faces from various angles and recognizing faces of different nationalities.
For those who are concerned about accuracy, it should be noted that some software comes with the option to set custom confidence thresholds, which can greatly reduce the possibility of the system returning a false positive. There is also the option to use two-factor authentication, such as face recognition combined with a pin code or key fob.
Once you’ve set up your smart home security system and granted access to the people you want to allow into your home, the system will automatically let those people in when it detects a match. No need for you to answer the doorbell, or to respond to a request to enter.
Facial recognition tools can be easily integrated into existing systems using an SDK or API.
Why face recognition is a better option than other biometric verification solutions in the context of home security
Biometric verification is based on unique behavioral and physiological traits, which include fingerprints, keystroke dynamics, facial features, gait, and voice print. Facial recognition appears to be a favorite due to its accuracy, ease of use, and no-contact sensing.
Facial recognition technology is here to stay, and will only get better with time. Smart technology has changed the story and has increased your options.
