With the rise of smart home, smart devices appear in front of us. In addition to smart sockets, smart routes, etc., they play some roles in life. As an intelligent doorbell, they are also part of this field, serving as the entrance to smart home. When you press the smart doorbell, whether the owner is at home or not, The doorbell will tell you in warm words, and EVIDEO Xiaodong is one of the smart doorbells that has done a better job.

On the outside front of the package are Xiaodong doorbell and Internet+. Here you can experience that the doorbell is related to the Internet, which reflects the characteristics of Internet+and indicates that it is an intelligent doorbell. There is also an official WeChat QR code next to it. For some questions about this doorbell, you can follow them to understand it. The customer service is also very patient to answer your questions.

Appearance and unpacking

EVIDEO small door bell, its appearance has improved the safety index of the home, and recorded visitors in detail. The outer package of Xiaodong doorbell adopts the pull design. It is made of environment-friendly hard paper, simple and elegant.

Take Xiaodong out of the sponge pad, I feel it is so light, and its small size is 82 * 57 * 19mm.

The fuselage is made of very solid matt white engineering plastic, which is resistant to falling. The front of Xiaodong doorbell is a 640 * 480 pixel camera. When someone presses the doorbell switch below, it will capture and record the picture and tell the owner.

Above the camera is a small hole, which is the microphone vent.

The speaker is on the left side. When you press the doorbell, the sound comes from here.

The key point is the design of the buckle, which may be nothing for other battery box covers, but it may not be very secure for the things pasted on the door. In addition, it is not easy to remove the buckle, which may be related to the hardness of the engineering plastic. You need to push down hard to take out the battery cover.

It's easy to install the small bell. Just tear off the sticker on the back and stick it to the right place on the door. The black adhesive on the back is very strong, and it takes a lot of effort to remove it, so don't worry about it falling off.

The Xiaodong doorbell is powered by four No. 5 batteries. However, when four batteries were installed in the original light body, it immediately became heavy. I don't know why it doesn't use lithium battery design, which reduces weight and is simple and convenient.

What is the inside of such a small doorbell? I went to disassemble it with curiosity.

It is relatively simple to disassemble the small door bell. The big switch on the front is composed of two small button switches, so visitors can make the door bell sound whether they press the left or the right side.

At the top of the battery slot is an integrated circuit board. Screw off the diagonal screws to see the structure

The circuit board is mainly composed of WiFi module and image processor

Speakers and microphones are connected to the circuit board with thin wires, so the disassembly should be very careful.

You can see that the speaker is still very small. When someone rings the doorbell, if the room is very noisy or the TV is very loud, the doorbell outside is still inaudible.

At the bottom is a 640 * 480 pixel camera, which is connected in a flat cable way. Open the card slot and take it out.

Speaking of WiFi connection, if you are connecting or changing the network for binding, you can reset the WiFi network through the button on the back of the motherboard, but this switch is too small to be detected.

In the accessories, the official also gave a doorbell sticker, pasted it and installed it on the door. Is it very warm.

APP Usage

Next, let's see how to use this small and delicate doorbell. By following the official WeChat, we can get the download APP link in WeChat. After the download is completed, we can open the APP to bind with Xiaodong. The binding process is very simple. You can use your mobile phone or email to register.

When binding for the first time, you need to press the doorbell switch. At this time, Xiaodong will remind you that the doorbell has not yet been bound to the mobile phone. At this time, you can bind by voice prompt. There are two binding methods. The first is sound wave as a signal, and Xiaodong microphone will bind automatically after receiving the information; The second is wireless configuration binding. In fact, there is not much difference between the two, but the first binding mode will make you feel more magical and special.

After the binding is successful, give Xiaodong a name. Open the home page, where the device status and signal are displayed. Of course, the binding installation records are displayed. However, after repeated tests, the mobile phone APP still shows that the online signal of the device is good after the battery is buckled down. I hope the official will fix this problem.

Of course, what if I change the WiFi network? As mentioned above, there is a WiFi reset button on the back of the fuselage, which can be reset after pressing. You can rename or delete the device in the device management menu.

When visitors come to visit you, the doorbell will work. The number of visits and Xiaodong can be recorded accurately.

Xiaodong's intelligence can not only record the number and time of visitors, but also record who the visitors are. It has a powerful photo taking function. Xiaodong pushes the photos to the owner at the first time. No matter whether the owner is at home or not, the mobile app can accurately obtain information, which is very convenient and quick to know the visitors.

After the door is installed in a proper position, the test shows that as long as the doorbell switch is pressed, Xiaodong immediately takes photos and pushes them. When the light is good, he can see the surrounding environment and the appearance of the people, but when the light is dark, the effect is not very ideal.

When the light is bad, the whole surrounding environment is blurred, and it is almost necessary to adjust the brightness. However, this brightness is not the sensitivity of the camera, but the brightness of the photo, so it cannot achieve the clear effect of taking pictures at night!

Summary and suggestions

As a part of smart home, Xiaodong doorbell has a small and delicate appearance. When a visitor presses the doorbell, photos are uploaded to the cloud, and the owner's mobile phone APP downloads and pushes accurate or visitor's identity information. When the child is alone at home, parents no longer need to worry. At that time, this small doorbell still had many problems and shortcomings, as follows:

1. Add LED display light, which can let visitors know where the doorbell is even at night;

2. Add equipment operation status, and know whether the equipment is online through the indicator light;

3. Replace the battery with rechargeable lithium battery to avoid disassembly trouble and improve the endurance;

4. Customize the voice prompt content, for example, the host can set the prompt for the visitor to press the doorbell, tell the visitor whether the host is at home, and the visitor can leave a message through the doorbell, or can talk back with the host;

5. The installation method needs to be improved. Once someone with ulterior motives takes this installation method which is directly pasted on the door, even if the phone is bound, it still makes people feel uneasy, so it is recommended to use the method of drilling and screwing for installation;

6. The mobile phone APP and firmware functions are too simple. I hope to add the mobile detection function. If I wander at the door for a long time, I can also capture photos or videos;

7. Loudspeakers can use one outside the door, one inside the door, and two induction doorbells. When visitors press the doorbell outside the door, the doorbell inside the door will also ring, so as to prevent the indoor sound from overriding the doorbell outside the door;

8. Add night vision function, even at night, you can take clear photos of visitors, or you can use it as a security device, kill two birds with one stone!
