Introduction: Why choose Hikvision EZVIZ?
As for why Hikvision Holdings' EZVIZ was chosen, the judges have to be patient and listen to my nagging for a while. I remember that it must have been 13 years since I first became acquainted with Hikvision. At that time, I had just left the society. Considering that only my parents were in my hometown, when I returned home in the second year, I found a local surveillance store to install two cameras and hosts for the gate and the hall of the house, and pulled the network cable. Does it seem to be 5M bandwidth or how much? My memory is a little fuzzy, I remember that the equipment at that time was all wired network, and it should be called "Haikang" at that time. The purpose of installing this monitoring system is to make it convenient for people to watch and protect their parents at any time. Counting from the installation, to rebuilding the new house in the old home and replacing the monitoring system that supports the wireless network, this set of equipment was eliminated under normal conditions after about 8 years of service. Later, I also bought one set for my sister, and one set for my self-built house in other places (one for the gatekeeper on the first floor and one for the children on the third floor), and these three sets of equipment are still in excellent condition. Over the years, there is no damage from wind and rain, typhoons, and lens blur caused by water entry.
EZVIZ is an Internet innovation business incubated by Hikvision, mainly engaged in the smart home business, and will be listed on the Science and Technology Innovation Board in 2022. EZVIZ was originally engaged in the smart camera business in the home environment. According to reports, it has ranked first in sales on the Tmall platform in the 618 promotion for many years in a row. Therefore, in terms of products, EZVIZ, like Hikvision, still has certain strength and technology, and is trustworthy.
Smart door lock:
The EZVIZ DL50FVS automatic face video lock is prepared for the new house rebuilt in my hometown. Because the new house built in the early stage is an old-fashioned house built according to my parents’ wishes, with some western elements added, it is a single-storey house. With the increase of the population, it is no longer enough to go back to live during the holidays, so I rebuilt this set after considering it again and again. At first I thought that the shape of the gate on the first floor was ready and I could install the door first, so I excitedly took this lock and asked the master to install the door for me, but the master told me that the door was not so fast to install, and I really put my own pigeons.
However, this couldn't stop me from wanting to experience it in advance. I took the lock back to my house in another place on the return trip. Each floor of the house is independently entered, and the gate on the first floor is a self-controlled centralized lock, so I will not touch it. There are also smart door locks (supporting) installed before the entrance door on each floor. I have long wanted to eliminate them. This time I just took the fluorite lock to experience it first.
The entrance door of the previous floor was equipped with a vein smart lock. I didn't pay attention to it in the early stage, but I was really tired of using it later. The emergency keyhole needs to turn the handle to put the key in, but when the handle was turned, it reached the side of the door and could not be opened properly. As a result, the door lock was out of power and the mobile power supply was almost unable to enter the door. Later, the door was opened after bending the second half of the key. Moreover, the finger veins are really unfriendly to the fingerprint recognition of children and the elderly. If you want to return or exchange later, the expiration date has passed, so friends must pay attention when buying smart door locks.
EZVIZ’s new product DL50FVS fully automatic face video lock (hereinafter referred to as: EZVIZ DL50FVS face video lock) has a good design for opening the door with an emergency key. It adopts a flat hidden design. In case the door lock is out of power and there is no mobile power supply for emergency, just push the micro switch to open the cover to unlock it. This design has no restrictions on various door frame designs and is very friendly.
EZVIZ DL50FVS face video lock and accessories:
accessories are not introduced, they are all available, no need to buy additional accessories, and the manufacturer also provides the first free installation service (valued at 500 yuan), so you don’t have to worry about a one-stop solution.
Among them, the lock cylinder is C-level security standard, and the matching key makes me feel good. The pure metal is very high-grade. Compared with the key of the old door lock, the difference is clear at a glance.
Detailed design and configuration:
EZVIZ DL50FVS face video lock body is composed of aluminum alloy body + AG matte tempered glass panel + customized extreme gray surface decorative cover. The main body cover is glossy, while the control area and handle are matte like frosted, the overall sense of grade has been improved very well.
The frame and handle support are all made of aluminum alloy. Generally speaking, the matching of color and material is just right, which belongs to the grand design style.
The external control panel and handle adopts the "offset handle design" that can be shifted left and right. This design can adjust the side position of the handle according to the door opening direction and the inner and outer door opening directions, so as to achieve smoothness and prevent hand pinching. From this point of view, the design can reflect the carefulness of the designer. The small design can give users a more comfortable and smooth use experience, which is worthy of praise.
In addition, the external fingerprint sensor is hidden behind the top side of the handle, which is more convenient in terms of the habit of using gestures outside the door, and is better than the front layout. In addition, in addition to the small handle, it is also equipped with a one-button full finger lock button, which is very thoughtful in design.
EZVIZ DL50FVS face video lock has a total of 6 unlocking and unlocking modes, namely 3D face unlocking, fingerprint unlocking, APP visual unlocking (supporting remote) password unlocking, temporary password unlocking and key unlocking, a variety of unlocking modes can meet different unlocking needs and emergency unlocking. The top of the front is the integrated area for 3D face unlocking, and a 200W pixel high-definition 1080P-132° ultra-wide-angle lens and infrared night vision are arranged.
The internal body of
is equipped with a 4-inch visual color screen, which supports visitors to press the bell to turn on the screen in real time.
installation:
If you have no experience in door lock installation, you can directly enjoy the first free door-to-door installation service worth 500 yuan presented by EZVIZ, a one-stop solution.
If you have some experience, you can also install it by yourself like me, and enjoy the fun of doing it yourself. The installation model of the EZVIZ DL50FVS face video lock is the standard hole position, which is consistent with the door lock of the room door. It only needs to be aligned with the original hole position for installation. There are only two wires for the inner and outer locks.
user experience:
6 major unlocking mode, password/temporary password unlocking and key emergency unlocking are relatively common and can be skipped. Personally, I am most concerned about the security and recognition accuracy of face recognition and fingerprint unlocking. The external devices (password area/lens area) of EZVIZ DL50FVS face video lock adopt radar sensing technology and infrared technology. When the human body is recognized, it will light up and start face recognition. Thanks to the embedded high computing power AI chip and the blessing of dual-core CPU, its sensing ability is indeed very sensitive.
3D face recognition module, equipped with a number of self-developed technology algorithms, has accurate recognition and security. Both adults and children can recognize it perfectly, even after wearing glasses or women wearing makeup, they can be recognized correctly through the algorithm.
In order to test the security, we took static photo stickers and dynamic videos for false recognition. The live recognition technology of the door lock (3D face live recognition module self-developed by EZVIZ) can be regarded as a security check. It has been tested more than 20 times, and there is no false recognition. The safety can be assured. After all, it has obtained BCTC enhanced living body certification and passed the "Ministry of Electronics Fifth Institute A-level security certification", so it is safe and secure.
Fingerprint recognition is a standard configuration of smart locks, but the recognition rate of different brands is very different. Take my previous vein lock as an example, it is difficult to recognize people under 15 years old and the elderly, and the recognition rate is only 20%. A friend's house is very fingerprint lock also has a similar problem. The fingerprint area of the EZVIZ DL50FVS face video lock is not only properly designed, but also has an excellent recognition rate. My little naughty can also accurately identify it. The old lock made him complain hundreds of times.
In addition, the infrared night vision also has excellent support for dark scenes at night. When the lights are completely turned off, the picture is clearly visible. The 200W ultra-clear wide-angle intake and the presentation of the 4-inch color screen are perfect.
As for the width of the camera image, it has something to do with the layout of the stair passage. Because the first staircase of the self-built house is next to the entrance door of the floor, the angle is rather tricky and parallel to the camera. Therefore, it is not a problem of not being able to pick up the wide-angle. The picture below is the effect of the wide-angle lens that I tested before it was installed. The picture picked up is much wider than the standard lens, which can fully meet the panoramic picking of the entrance door and passageway of commercial and residential buildings.
At present, the smart locks on the market basically have their own client APP, but most of them do not support client-side control unlocking/remote unlocking, which lacks practicality, including my previous vein lock. EZVIZ DL50FVS face video lock can be managed through the "EZVIZ Cloud Video APP", and can be unlocked/remotely unlocked, remote management, smart home linkage and other operations through the APP, bringing users a more efficient experience.
Through the client setting menu, you can see that this EZVIZ DL50FVS face video lock has many functions, including a variety of security functions, such as visitor detection, children going out detection, express package detection (these functions are based on the accumulation of EZVIZ video and vision technology, which is innovative and leading in the industry), one-key arming, plus the built-in sensor detection technology of the door lock, such as abnormal wandering alarm at the door, live body recognition and other functions, it is really hard to build security nuclear. It also supports 24-hour prevention and control capture, and locks and saves important images in the built-in storage (the machine has 8GB of automatic cycle storage space)
and cloud storage. Dual storage ensures the preservation of important evidence.
In addition, ringing the bell outside the door automatically activates real-time visualization, APP push, and real-time video on the internal screen. If there are only elderly people, children or women in the house, if they find out that they are strangers, they can use the voice-changing technology to imitate the voice of a man to play a role in intimidation. In addition, the above-mentioned various safety detection functions, when an abnormality is found, will immediately push a message or make a call notification, so as to avoid unnecessary miscellaneous things in time.
Other aspects such as the basic usage status of the smart lock, power display, signal strength, user management, screen settings, unlock settings, screen settings, battery management, video management, privacy and multi-person sharing, and unlock records, etc., have rich and practical functions.
Secondly, EZVIZ smart lock also supports automatic full lock when closing the door, automatic unlocking and countdown to lock, and countdown face re-recognition. Personally, I am most satisfied with the function of countdown face re-recognition. In this way, every time we go out, when we wear shoes at the door after closing the door, the face recognition of the door lock is in the countdown recognition state, which will not cause the recognition to open the door again. Countdown is convenient for users to define freely, which is very user-friendly.
Summary:
Although there are many styles of smart locks and face-face video locks in the market, in terms of overall security technology, EZVIZ has more than ten years of visual technology accumulation, innovation, and self-developed technology, and has inherent hard-core advantages in security. Self-developed 3D face recognition module + BCTC enhanced living body authentication, as well as multiple layers of excellent security features such as "A-level security certification of the Ministry of Industry and Information Technology", are well reflected in this EZVIZ DL50FVS automatic 3D face video lock. Secondly, the design style, material and small accessories (keys) are all very high-grade. I personally think this is a good lock that is worth recommending to relatives and friends!
suggestions:
1, the micro switch of the hidden emergency key cover adds a "top cover/push cover" design, the push switch supports pressing the top pressure to eject the cover (or use magnetic repulsion to eject), currently only supports pushing, and the cover is not very easy to pry out.
2. This suggestion is bolder. If the camera can adopt a movable design (left and right adjustment, similar to a recorder camera), so that it can perfectly match the tricky angles of some floors. I believe that if this design is launched, it will be very popular.
