When the smart door lock has entered tens of millions of families, there are still many security risks such as losing the courier / maliciously picking the lock at the door, which always makes consumers feel powerless, and the fingerprint recognition is not sensitive, etc. What kind of smart door lock is safe and convenient? Today we want to experience the finger vein smart door lock S50M from Luke, which is also the first smart door lock product that integrates the function of cat's eye and finger vein.
At present, the biometric identification method used in smart door locks mainly relies on fingerprint recognition or face recognition, and some products also have iris recognition and voiceprint recognition, but the most secure iris recognition is relatively poor in terms of recognition efficiency and experience convenience, while fingerprints, voiceprints and face recognition have strong replicability and are not safe enough.
Slowly, the advantages of finger vein technology in the application of smart door locks have emerged, and this biometric recognition technology that takes into account the accuracy, convenience and uniqueness of recognition may become the mainstream recognition method in the future of smart locks. Luke has a lot of products that use finger vein technology, which has become the smart door lock brand with the most application of this technology on the market.
Finger vein recognition is a kind of vein recognition, medical vein recognition first through the vein recognition instrument to obtain a personal vein distribution map, from the vein distribution map according to the special comparison algorithm to extract the characteristic values, through the infrared CCD camera to obtain the finger, palm, dorsal vein images, the digital image of the vein stored in the system, the characteristic value storage. When comparing veins, the venous map is taken in real time, the characteristic values are extracted, and the digital image is extracted by advanced filtering, image binarization, and refinement methods, which are compared with the venous feature values stored in the host, and the venous characteristics are matched by a complex matching algorithm, so as to identify the individual and confirm the identity.
On the Luke S50M smart door lock, vein recognition is only for the finger, through the identification module on the back of the door lock to collect the vein data of a single finger, the whole process is collected the inside of the finger up / middle / down three dimensions, in order to ensure that the finger can be accurately identified under different holding postures can be accurately identified vein data for matching unlocking.
Vein recognition, like iris recognition, is a highly personalized biometric method, and both exist in the human body and cannot be replicated. The data shows that the probability of two people having the same finger vein is one in 3.4 billion, even twins will not have the same finger vein data, and the fingerprint and face misidentification rates are one in 200,000 and one in a million, respectively, and the vein data does not change with age, which is safer than fingerprint, iris or face recognition.
And finger vein recognition is more comfortable to use, the conventional open door posture can put the finger on the recognition module, no longer need to align the eyeball like an iris to the recognition module, the whole process is very natural.
The benefit of finger vein recognition is not only uniqueness, but also accurate recognition for users whose fingerprints are not obvious or have dead skin and water stains on their hands. For example, this time we are to the company's fingerprint is not obvious colleague as the object of testing, usually fingerprint punch card machine needs to be recognized many times to succeed him, in the Deer S50M after multiple tests can do a single successful unlock, completely solve the fingerprint incomplete leading to identification errors.
As the first line of defense to protect the family, the smart door lock can monitor the movement outside the door in addition to security. Therefore, Luke S50M also added the cat's eye function, adding an ultra-clear large wide-angle cat's eye camera to the door lock, which can monitor the condition of the door at all times.
This camera can shoot 1536P resolution of 16:16 ratio picture, compared to the usual 1080P picture, the collected picture area is larger, especially the increase in the upper and lower ends of the picture collection area, no matter what kind of height or crouching / lying down at the door can be easily photographed, if the usual express delivery is placed at the door, deer S50M can also be taken clearly, not afraid of someone stealing.
In actual tests, the clarity and viewing angle of this camera are still very good, installed on the door will have a very considerable line of sight area, and it also supports infrared shooting, with commercial camera level F2.0 large aperture, the amount of light doubled, when the corridor or night light will switch to infrared shooting, at night can also clearly record the face information of the person at the door.
In addition to monitoring the security status of the door and pushing messages in time, this cat's eye can also make real-time video calls with visitors outside the door.
Users can use this cat's eye to achieve remote video calls, or you can also link up with the mijia Xiaoai classmates and other screen devices to view the situation at the door, such as if someone outside the door rings the doorbell, you can use the small love touch screen speaker to talk to the visitor outside the door with one key, without unlocking the mobile phone, which is very convenient. Considering the safety of women living alone, there are also different voice changes during video calls to prevent them.
As a flagship door lock, the hardware is naturally equally outstanding.
Luke S50M itself adopts a black and gold color, black as the main body and then gold trim, the door lock should have the calm temperament to hold in place. And the outdoor part of the panel adopts polished mirror design, and the indoor part is matte frosted texture, which is very in line with the different styles of indoor and outdoor styles in the home situation.
The outer part is from top to bottom is the ultra-clear cat's eye, the doorbell button, the hidden digital LED key area, and the physical keyhole, while there is also an NFC recognition area in the number key, which can be identified and unlocked by the NFC card. The position on the posterior side of the front refers to the vein recognition area, and the normal opening posture can easily place the finger that needs to be recognized in the groove, and the door can be opened after unlocking.
The door lock adopts in-line C-class lock cylinder, stainless steel fully automatic lock body, its physical strength has been very good, but also built-in to prevent small black boxes and violent unlocking alarm module, further guard the safety.
The interior section, from top to bottom, is followed by the physical door opening button, the electronic anti-lock button and the emergency knob. When the user unlocks the door, he needs to double-sense unlock the lock, and needs to touch the handle sensing area while pressing the physical unlock key, so that he can avoid small children or pets from misoperating the unlock indoors.
After the battery cover of the indoor panel is removed, it is the battery compartment, the lock body of the Deer S50M and the cat's eye adopt a separate power supply method, the door lock itself supports 8 AA batteries to provide continuous power supply for up to 12 months, and the cat's eye uses a rechargeable 5000mAh lithium battery module to provide a power supply cycle of 5-8 months, and will be reminded in advance when the power is insufficient to avoid accidents.
On the whole, Luke finger vein smart lock cat's eye model S50M is still very attractive under the market price of 2699 yuan, the new product and the discount is only 2099, especially it applies two major security measures of finger vein unlocking and cat's eye monitoring at the same time, which not only improves the identification security of the smart door lock, but also provides monitoring capabilities for the situation in front of the daily home door. The exquisite design and thoughtful features make it one of the most worthwhile and cost-effective smart door locks.
