Speaking of smart locks, I am really an experienced user. I have bought semi-automatic fingerprint smart locks and fully-automatic fingerprint smart locks before and after, but I feel uncomfortable using them. Especially every time I go home carrying large and small bags of things, I sadly find that I have to struggle to open the door with my hand, which is really troublesome. My husband complains every time that he wants to change the door lock. I did a lot of homework and fell in love with the K20 Max Plus fully automatic 3D face recognition unlocker at first glance. After using it, I was really impressed. After going through so many pitfalls, I finally bought it. A suitable smart lock.

Having bought so many smart locks, I have summarized 5 key points for choosing smart locks. If you follow them, you will not go wrong.

1. Choose a professional smart lock brand

Tell the truth on the market There are so many brands of smart locks. When a friend changed his door, the manufacturer kept promoting unknown smart locks, thinking of installing them together, but the result was overturned. In less than half a year, the smart lock had no power and could not be charged, so it was locked outside. I spent hundreds of dollars to pick the lock and get in. It is recommended to choose a well-known brand in the professional security field, especially one that specializes in smart locks, which is more professional. For example, the Caddis brand I chose this time has been deeply involved in the lock industry for 36 years. It has more than 3,000 stores across the country. If there is a problem, after-sales service is guaranteed, and the locks are safer and more reliable.

2. Professional and safe unlocking method

There are many ways to unlock smart locks, mainly including door cards, fingerprints, passwords, and more advanced ones such as face recognition, remote authorization temporary passwords, etc. Many people do not accept smart locks mainly because they are worried about fingerprint recognition and Facial recognition has security risks, and you worry about being impersonated and opening the door, so you can focus on these two aspects when choosing a smart lock.

①Face recognition: Select 3D face recognition, no matter wearing a hat or wearing eyes, insufficient light, etc., it It can accurately capture you when you open the door, and others cannot use photos or selfie videos to unlock it. It is very safe. In addition to 3D face recognition, the smart lock has a remote viewing peephole for more peace of mind. You can see the situation outside the door through your mobile phone and peephole. , you can detect anything wrong in advance

②Fingerprint recognition: Do not choose a light fingerprint system, as it is easy to leave fingerprint marks, and it is impossible to distinguish between real and fake fingers. You are afraid that bad guys will copy the fingerprint to unlock the door. It is recommended to choose semiconductor fingerprint recognition, which has accurate identification and strong security.

3. Look at the lock cylinder

Lock cylinders are divided into three grades ABC. The unlocking time of grade A lock cylinder is 1 minute, the unlocking time of grade B is 5 minutes, and the unlocking time of grade C is 10 minutes. It is recommended to choose a lock core of grade C or above to be safer. .

4. Dummy password

Worried about passwords being spied on, smart locks with a dummy password function will be more secure. When entering the password to unlock, enter it casually, as long as there is a continuous and complete real password in the middle.

5. Safety protection design

In addition, it would be better if the smart lock has safety protection designs such as anti-cathole unlocking, emergency unlocking knob, anti-electromagnetic interference, electronic anti-locking function, alarm when the door is not closed, etc., to improve the safety factor. , these all reflect the level of smart lock security technology

After many comparisons, I bought Caddis K20 Max Plus, which meets all the above purchase points. Now I will share my experience of using it. If you want to buy it, you can take a good look.

1. 7 unlocking methods are safe and reliable

Compared with the fingerprint lock I used before, every time I use this smart lock, I feel that my life quality and happiness have improved. It is particularly troublesome to open the door when your fingers are sweaty or have wrong texture. It is very inconvenient for the elderly to have to enter a password to open the door because their fingerprints are blurred. Plus\’s 3D face recognition sensor is really fast. The 144° wide-angle lens will start to recognize you when you walk about 1 meter away. It also comes with intelligent fill light. There are no bugs no matter day or night, and you no longer have to hold it. A bunch of things have to be divided up to open the door.

You can also use the app to remotely set a temporary password valid for 30 minutes. If your friends arrive early, you can open the door and take a rest.

In addition to 3D face recognition, its fingerprint recognition uses the internationally renowned brand Swedish FPC semiconductor fingerprint recognition, which is as easy as unlocking a smartphone and can be recognized in less than 0.5 seconds. It has good recognition and security. High. In addition, there are virtual passwords, keys, two-factor authentication, and CPU security door cards that are not afraid of being copied or lost.

2. Visual peephole and doorbell

This smart lock comes with a visual peephole, which saves you the cost of installing a separate peephole. The wide 144° wide-angle lens and 1080p high-definition image quality can clearly see the situation outside the door, even if there is a slight movement. Check the situation outside the door anytime and anywhere on the mobile app, that is Even in low light, you can see clearly. In addition, the smart lock has a doorbell function. When someone rings the doorbell, my phone will have a caller ID. After answering, I can make a video call. Occasionally, when a takeaway arrives and I am not safe at home, I can call it through The mobile app is a very convenient and practical function to talk to the delivery boy.

3. Opening and closing the door is convenient and safe

In the past, when opening and closing the door, I was always worried about forgetting that the lock did not pop up and closing the door successfully. Now with the Kaidis smart lock, I don’t have this worry. After closing the door, its main deadbolt pops up automatically, so you don’t have to worry about forgetting to lock it. It is convenient to open the door at home, or you are afraid of someone following you. You can hold the handle and pull the door open at the same time. The door lock sensing time is 1 second faster than ordinary locks, which is especially convenient when you are in a hurry to go out.

4 and 11 heavy alarm security

The security of smart locks is also very important. This smart lock comes with 11 levels of alarm security, including a false door alarm if the door is not locked, a door lock abnormality alarm, and anti-prying. Alarm, arming alarm, low battery reminder, anti-test lock, wandering alarm, anti-small black box interference function, natural anti-cat eye function, anti-accidental opening by children, anti-opening by large pets. If I forget to close the door a few times, it will immediately send out a voice reminder of \”the door is not locked\”, which is really great for a careless person like me.

5. Convenience of mobile app control

I think there is another great thing about it What\’s more, many functions can be controlled using the app. Through the app, you can remotely send temporary passwords, remote real-time unlocking records, alarm information, door lock status, lock battery, and online key management, which is smart and convenient. The original smart lock had no obvious battery reminder and was locked out several times. Fortunately, I had a spare key in the car and could open the door. Now when the battery of this smart lock is too low, both the door lock and the app will send out reminders. I can also clearly understand the door lock usage records through the app, who opened the lock when and how, and the situation of my family members when they return home is very clear, which makes me feel particularly at ease.

If you plan to install a smart lock in your home, it is recommended that before buying the lock, it is best to consult customer service in advance to measure the size, otherwise you will not buy it. After coming back for a long time, I found that it could not be installed, it was troublesome to return or exchange goods, and I was worried that the door would be damaged. If you want to choose a smart lock with good security performance and easy to use, after using this Cadiz K20 Max Plus smart lock, you feel that it is quite good and it is worth recommending.
