AI smart cat's eye | multi-device cross-screen linkage | noise reduction fully automatic lock body
What is 3D structured light face recognition technology? Safe and reliable face recognition technology.
Invisible light spots are projected into the face area, facial details are captured, and a unique face spectrum is carefully drawn. After deep calculation matching verification, you can walk to the door without contact and automatically unlock it by swiping your face. When you leave home and close the door, the face recognition defaults to sleep for 15 seconds, so you don't have to worry about turning back to open it by mistake. At the same time, it has 3D live anti-counterfeiting detection, which effectively prevents photo and video attacks and cracking.
Face recognition, the whole family can open the door conveniently
Whether it is day or night, you can capture face information dynamically and accurately identify it. The whole process is contactless and fully automatic. Children don't need to stand on tiptoe, adults don't need to bend over, and the elderly don't need to worry about the wear and lightening of fingerprints. 3D structured light face recognition is a face recognition technology that is truly suitable for the whole family.
Height coverage range 1.2-2m | Recommended face recognition distance 0.4-0.8m.tookfun
* The user can recognize the height range of 1.2-2m when standing about 0.65m in front of the door. It is recommended to stand in front of the door lock for face recognition unlocking. If the part is affected by strong light and overexposed, the recognition will be affected. The specific situation is subject to actual use.
Even if your style changes, you can open the door smoothly
* Try not to cover your eyebrows and eyes when changing your hairstyle, otherwise it will affect the recognition effect. If there is any recognition abnormality, it is recommended that the user re-enter the face to ensure the subsequent unlocking experience. Due to the working characteristics of the face recognition module, wearing some special sunglasses will affect the recognition experience. The specific situation is subject to actual use.

Installation conditions
Step 1: Determine whether installation is supported based on the following dimensions.
The following environments do not support installation: the door thickness is not within the range of 40-120mm or the door gap width is not within the range of 2-8mm.
If any of the following conditions occurs, installation will not be possible:
1. The door lock panel width is less than 110mm;
2. The lock body eccentricity L1 or L2 is less than 20mm;
3. The distance between the door handles of the inner and outer doors is less than 160mm
4. Wrought iron doors, fence doors, double lock doors, glass anti-theft doors, bull head locks, hidden locks, alloy copper doors, mobile doors, folding doors, open-air outdoor doors, etc. cannot be installed;
5. If the filling material inside the door is fragile or the chemical reaction with the air will produce an acidic/corrosive environment, it cannot be installed: for example, the filling material inside the door is gypsum or perlite, etc.
Step 2:
1. This product is equipped with a fully automatic lock body. If the original lock body is a standard lock body, it can be adapted and installed:
If the original lock body is a King lock body, King guide plate and door plate can be used for adaptation and installation. The scheme is shown in the figure below.
2. Description of the sky hook
*Since the fully automatic lock body does not support the sky hook, if there is a sky hook on the original door, it is necessary to remove the sky hook inside the door for installation to avoid the risk of the sky hook falling off and being unable to open the door.
Determine whether there is a sky hook: If there is a lock tongue at the top and bottom of the door (as shown in the figure below), it means that the door has a sky hook, otherwise it does not.
The sky hook is linked to the main lock tongue structure of the original King lock body, and its main function is to extend the time of violent door opening. In the face of current technical unlocking, it has no protective effect, and it is easy to get stuck or fall off when paired with a new lock after long-term use. In case of emergency, the presence of the sky hook may affect fire rescue, so it is recommended to remove it.
Note
* The “8-month battery life” is the battery life evaluated by the Luke laboratory under the condition of simulating 10 door openings and closings per day, 25 videos, 10 seconds per video, and normal temperature of 25°C. The time is for reference only. The actual battery life varies with the number of door openings and closings and the use environment. Please refer to the actual situation;
* When using only dry batteries, face recognition and AI smart cat-eye functions cannot be used. Battery performance will decrease in low temperature environments and battery life will be shortened.
* The panel can withstand a pressure of 8000N. The test was conducted by the Luke laboratory. The outer surface of the product was placed flat, and a circular pressure head with a diameter of 50mm was used to align the weak parts of the lock shell (excluding reading devices such as card readers, password keyboards, fingerprint collectors, etc.). The pressure was gradually applied at a loading speed of 10mm/min to reach 8000N and maintained for 60s. After unloading, the lock shell was checked for obvious deformation and damage.
* -10°C-55°℃ is the working temperature range. After 4 hours of high temperature (55°℃±20℃) and low temperature (-10°C±30℃), the door lock is in working state. No state change occurs during the test. After the test, all functions of the door lock are normal.

Q＆A
1. What should I do if face verification fails?
① Make sure that the facial features are not blocked. Wearing a hat, a mask, or long bangs may block the facial features of a person, so that sufficient facial features cannot be obtained and recognition fails.
② You can adjust the distance forward and backward to try
③ If the light environment in front of the door changes a lot, you can enter more than one face data at the same time to try,
2. Does it support face recognition unlocking for children or the elderly?
It supports face recognition unlocking for children and the elderly. Currently, face recognition stands about 65cm in front of the door, and the height that can be recognized is 1.2m-2.0m. If the height is too high to be recognized, you can take a step back. Users below 1.2m or above 2m cannot be effectively entered and recognized because they are beyond the recognition range. It is recommended to use other unlocking methods.
3. Does wearing a hat, a mask, or long bangs affect the performance of face recognition?
It has a certain impact. To ensure the safety of face recognition, it is necessary to ensure that the facial features are not blocked during face recognition. Wearing a hat, a mask, or long bangs may block a person's facial features, so that sufficient facial features cannot be obtained, resulting in recognition failure.
4. What situations may cause the facial recognition component to fail to work?
If the surface of the facial recognition component is dirty or the protective film is not torn off, it cannot work properly. You can clean the obstruction and restore the facial recognition function.
5. How to open the door normally indoors, do you also need a fingerprint?
① No fingerprint is required
② The way to open the door indoors is to press the door opening button. Hold the door push-pull handle and press the door opening button at the same time to unlock it.
③ Or use the emergency unlocking knob, make sure the knob is turned clockwise or counterclockwise to the maximum, and push/pull the handle to open the door;
6. What should I do if the fingerprint is not easy to use?
Smart door locks support people aged 7 to 70 years old, but it depends on the development and wear of the fingerprint. Some people may not be easy to use. If the fingerprint is intact and still not easy to use, it is recommended to re-enter a fingerprint. During the entry process, try to increase the entry area as much as possible, and use the area entered at that time during recognition.
7. After closing the door, the alarm still sounds?
Check whether the door is completely closed. You can push/pull the door by hand until the white lock indicator flashes or the motor locks.
8. What should I do if the door lock is out of power? How to replace the lithium battery?
① Open the rear panel cover and remove the lithium battery.
② Please use a power adapter with an output parameter of 5V/2A for charging. Exceeding this parameter may cause damage or danger.
Disclaimer: The company does not assume any legal responsibility for battery damage, leakage, or fire hazard caused by failure to use according to the instructions.
9. Lithium battery charging indicator?
① Battery indicator is always on: Charging
② Battery indicator is off: Fully charged
③ Battery indicator flashes: Charging abnormality
Note: Please use a power adapter with an output parameter of 5V/2A for charging. Exceeding this parameter may cause damage or danger.
10. How to replace the dry battery?
Open the rear panel cover and remove the dry battery battery. Replace the No. 5 alkaline dry battery. In order to extend the battery life and prevent battery leakage, it is recommended to use a smart door lock dedicated battery or an [official genuine] brand battery. Otherwise, the battery will leak, causing the door lock to fail, which is not worth the loss. Check the battery power regularly. It is recommended to bind the Bluetooth gateway so that you can check the battery power at any time. You will also receive a reminder when the power is too low. If the door lock is out of power, you can use an external power supply to temporarily unlock it.
Note: Do not mix old and new batteries, and do not use rechargeable batteries.
11. What should I do if the door lock consumes power too quickly?
In the mobile phone APP, “Door Lock Settings–Camera Settings–Camera Working Mode” is set to Event Recording Mode B (Super Power Saving) to increase the battery life. When a security incident occurs in the door lock, such as the door lock being pried, it will record the video. You can also adjust the camera working mode according to your own usage habits
12. Why does the doorbell light occasionally not light up?
The human infrared sensor used in the door lock will be affected by the ambient temperature. When the human body temperature is close to the ambient temperature, the human body is blocked by thick clothes, wearing a mask, and the skin is less exposed, the door lock's sensing sensitivity may decrease. When the human body is not sensed, the doorbell light will not light up automatically. It is recommended to change the sensitivity in the camera settings to medium or high sensitivity to solve this problem.
13. Why is the video missed?
① Ambient temperature: The smart door lock PIR sensor works by detecting the temperature difference between the human body and the background environment. If the ambient temperature is close to the human body temperature (about 37°C), the difference between the human infrared radiation signal received by the sensor and the background noise signal is reduced, and it may be difficult to distinguish the human body heat
② Movement speed: Movement too fast or too slow will affect the detection effect of the sensor. Too fast movement may exceed the sampling frequency of the sensor, resulting in missed detection; too slow movement may cause the sensor to mistake it for background noise.
③ Movement direction: Horizontal movement (entering the door lock range horizontally from the front of the door) is easier to detect, while longitudinal movement (approaching the door lock from the front of the door) may not be easily identified if the front of the user's home is a straight and deep corridor, and the user's body movement is too small when approaching the door lock.
14. Will the door lock automatically lock if the door is not opened after the indoor/outdoor verification is passed?
If the door is not opened after the indoor/outdoor verification is passed, the door lock will automatically lock again, but due to the different states of the door, it may appear half-closed (seemingly closed, but not closed). It is recommended to manually close the door again to ensure that the door is closed.
15. How to use the indoor emergency knob to open the door, is the rotation direction clockwise or counterclockwise?
Make sure the knob is rotated clockwise or counterclockwise to the maximum, and push/pull the handle to open the door. The direction of rotation is the opposite direction of the door frame or lock tongue.
16. How to choose the door lock guide?
The standard size is right-angle double hole 24*240. Select the most suitable guide piece according to the original door lock size measured and fed back. Supports Overlord lock body.
17. How to enable and disable the electronic anti-lock, and how to open the door outdoors after enabling it?
When you need to enable the electronic anti-lock, you can press and hold the electronic anti-lock button on the rear panel for 1.5 seconds. The red light will be on for a long time, accompanied by a successful opening sound effect, indicating that the opening is successful. The red light will go out after 3 seconds. To unlock the anti-lock, press and hold the electronic anti-lock button for 1.5 seconds (the red light will be on at the same time), accompanied by the unlocking anti-lock sound effect, and the anti-lock will be unlocked. The electronic anti-lock function can also be turned on or off in the Mi Home APP after the mobile phone Bluetooth is connected to the door lock locally.
Tip: After the electronic anti-lock is turned on, only administrator privileges and mechanical keys can unlock the door outdoors.
18. What is the away mode?
When you go out, you can manually arm and link other devices to execute smart scenes. It is recommended to create a smart (select “away mode” under the “if” condition). You only need to click “away mode” on the front panel when you leave home to enable this function.
Tips: This function needs to be used with a Bluetooth gateway.
19. What is 3D structured light?
3D structured light face recognition is to build a 3D face model by irradiating the face with a speckle projector and reflecting the speckle back. When comparing faces, 3D face information is included, thus achieving the effect of 3D face recognition.
