About the past of children's telephone watches  

With the continuous emergence of adult intelligent wearable products, children also have a strong desire for intelligent wearable products. When parents operate smart phones, and when parents play with sports bracelets and sports watches, children see and learn. With the development of the times, children's telephone watches came into being. Parents can call their children and locate their children through their children's phone and watch; Children can call their parents with a watch to convey their attachment to their parents. Children's telephone watches set off a new climax of intelligent wearable products.

However, while children love children's telephone watches, whether anyone has seen the story behind children's telephone watches when parents communicate with their children through watches. Information security is a problem that must be considered and solved urgently. Once the information hacker attacks the manufacturer's server, he will obtain the data saved in the cloud server by the user through the information vulnerability, obtain the relevant information of the children's phone watch, and locate the children's phone watch to obtain the children's location. Information hackers can obtain private information through users' past call records. In other words, the so-called children's telephone watch that brings security to parents and children, in fact, just exposes the user's information privacy.

In the past few years, the National Information Security Center has announced several unqualified children's telephone watches. The main problem is that the manufacturer does not limit the number of errors in the password of children's telephone watches. In other words, a four digit password can be broken in a short time. Therefore, the server vulnerability of the manufacturer of children's telephone watches is a very terrible problem.

Since CCTV exposed unqualified children's telephone watches and exposed potential safety hazards, the state has made stricter monitoring on children's telephone watches. It was at this stage that Mi Tu children's telephone watch appeared. With regard to information security, I don't have the ability to steal information, so I don't have the ability to identify whether the manufacturer's cloud server has loopholes. Let's leave this problem to the professional technicians of the National Information Security Administration for identification.

You have received Mi Tu!

I wonder if all children like children's telephone watches very much. At the beginning, when my child's classmate imitated to call his mother with a children's telephone watch, my child cast an envious look, because the child apparently had used a children's telephone watch at home. Now, when I brought my son a telephone watch, he almost rushed over and excitedly asked me to put it on, saying, "I also have a children's telephone watch". Well, I know. I'm satisfied with him.

I brought him back Love to play computer games (That is, the former Lei Feng. com) The trial product provided to me -- Mi Tu children's telephone watch. Because it was delivered randomly by the manufacturer, the women's pink was received. However, this does not affect his son's love of Mi Tu at all.

Mi Tu should be considered as one of the products I have tried with complete accessories, including: manual, San Bao certificate, charger, and reset awl. Now many of the trial products are engineering sample machines and do not have instructions, so when studying the trial situation, it takes a lot of effort to study it thoroughly. Therefore, I hope that manufacturers participating in the trial will try their best to provide instructions. Because not all probationers are experts.

The dialogue function of Michare children's watch calculates the amount of use through data flow, and calls are calculated through mobile phone card. There is a film on the surface of the watch. There are indication marks on the film, marking the function of each key. The voice key in the upper right corner carries the voice message function with the mobile app, and can also make calls. At the lower right corner, there is a small man like button, which is the watch's address book. You can select to call a family member through this button. The four sequins in the middle are charging ports. The speaker is on the other side of the watch screen, and there is a small hole below the dial, which is a microphone.

The watch and mobile app dialogue function is similar to the WeChat message dialogue. The children press and hold the voice key to record, and release the key to send the recording to the mobile phone app. Similarly, parents can reply to children's conversations from their mobile apps.

Rough and cute

The rice bunny adopts dot matrix screen, with big red dots arranged into lovely patterns. With the lovely childlike voice and huge eyes flashing on the screen, Mi Tu is still attractive to children. Although Mi Tu can bring fun to children's interaction, from the perspective of parents, this dot matrix screen is really a toy, slightly rough. I would like to think that if I could be more precise

The watchband of Mi Tu is made of silica gel and has a certain width, which fully protects the wrist of children. The strap has five adjustment holes, and parents can adjust the length of the strap according to the thickness of the children's wrists. The adjusting buckle is a safety lock with upside down protection, which can prevent children from throwing away their watches while running.

Make a phone call

Children's watches are for children. It is necessary to look good, but more importantly, they are easy to operate. Just ask, a 1000+watch is affordable, but is it suitable for children to wear? Can children operate?

The function of the meter rabbit watch is very simple. There is a phone card in the watch. When registering Mi Tu, parents will ask to upload ID card photos and photos of parents holding their own ID cards. Personally, although this can protect the interests of the country, it has certain risks to user information security. Parents can call their children only by calling the card number in the watch. But when children call their parents, they need to call their parents' phone numbers from the phone book button on the lower right corner of the watch, and then dial them through the voice key on the upper right corner. If more than one person's phone is saved in the phonebook, you can click to switch. The watch will voice to indicate who is calling the phone. For example, father and mother. Phonebook is set from the mobile app.

About endurance

The screen of Mi Tu's telephone watch won't light up for long. It only lights up when the user starts the machine, makes a phone call, or operates the watch. Therefore, the watch doesn't use much electricity. However, the watch itself does not show the power, nor does it show the on-off status. Therefore, users do not know the status of the watch. Normally, I will try to switch on and off the mobile phone to determine the status of the watch. The user can confirm the power of the watch through the mobile app, which is also the only way to verify the power of the watch. The mobile app can shut down the watch at the same time. The phone automatically turns on the power when it is charged.

Children's telephone watch, nicknamed watch, is actually a mobile phone. Therefore, it has a certain degree of radiation. Personally, I don't have a professional instrument to measure radiation, but I still recommend children not to wear watches for a long time unless necessary. The watch is not used frequently, and there is no screen display when the watch is asleep, so the power consumption is very low.  

About Security Positioning

I believe that the original intention of choosing children's telephone watches is not to buy a toy for children. The selling point of children's telephone watch is "safety and positioning". So, is the positioning accurate? Is it safe? Here is the moment to witness miracles!

Let's start with three sorries, sorry，sorry。 For the safety of my baby, I covered up the map and removed the relevant location marks. As can be seen from the map intercepted from the mobile app, Mi Tu marked the location of the children's phone watch. However, not far from him, I marked the exact location with. That is to say, there is a certain distance difference between the automatic GPS positioning of Mi Tu, and the error is less than 20 meters. At the bottom of the map, the specific address of the marked location is given (hidden by me).

As can be seen from the map above, there are three function options at the bottom: telephone, chat and history. Among them, "history" can be seen from the daily route of the phone and watch. If children walk alone after school, parents can see the children's walking route in real time in the road map.

One of the highlights of MIBU's safety is not just GPS positioning. Parents can select home and school (or common addresses such as grandparents' home) for marking in the map, and Mi Tu will automatically set 250 meters around the selected location for monitoring. If the children go out of this activity range, the rabbit will send an alarm like the app. This function effectively monitors children's security problems.

However, the same problem still exists. If the information between Mi Tu and the app is intercepted by criminals, the criminals can clearly understand the children's location dynamics and the information communicated with their parents, which really brings a considerable degree of security risks to the children.

About Motion

After more and more attention has been paid to sports, not only adult white-collar workers and sedentary people will pay attention to sports and fitness, but also Mi Tu has developed the step recording function of sports and fitness for children, and marked the energy consumed. Parents can set goals for children to exercise every day. The system automatically sets the daily exercise amount to 8000 steps. Sometimes I secretly wonder why this function is not supplemented with sleep monitoring function, which is more practical.

About Control

It is defined as control because of my personal profession and preferences. For the Mi Tu watch, it is more about controlling the time. The meter rabbit watch has set up class time, sleep and sleep time for students, better control the students' work and rest time, and prevent students from relying on the operation of the watch excessively. Parents can set according to the rest time and class time of children, and block the watch signal for a certain period of time to prevent harassment. You can also set an alarm clock to wake children up for school.

About Properties

The endurance of the watch was introduced, but the standby time was not clearly stated. Here's a detailed introduction. The watch gives two personalized modes: power saving mode and performance mode. Users can choose according to their needs. In the power-saving mode, manual positioning and voice intercom are available, and the standby time is about 5-6 days. In performance mode, it can automatically locate and improve voice speed. It will be in standby for about 1-2 days. But after many days of trying, this is a conservative calculation, and the actual standby time will be longer.

Children more or less throw things everywhere. In order to find the watch smoothly, the app has the function of finding the watch. Under this function, the phone will make a sound when it is turned on. However, if the watch is lost for more than a week, which leads to power failure and automatic shutdown, congratulations, you can consider buying a new watch for Baby.

About money

Here, near the end of the report, I would like to thank Lei Feng for giving me the opportunity to try it out, and also thank the manufacturer for being considerate and charging 10 yuan for the watch to complete the evaluation. The child used the dialogue function to send me several voice data, which cost 0.03 yuan. I didn't take a screenshot of the money spent on the phone calls afterwards. The phone card number is from other places in Guangdong, so I usually call my watch with my mobile phone to save the long-distance+roaming costs of my watch.

About the future of Mi Rabbit

  Mi Rabbit children's telephone watch is produced and sold by Xiaomi entrusted Shanghai Xiaoxun Technology Co., Ltd. It belongs to Xiaomi ecological chain. I am not familiar with the brand of Mi Tui, but I believe everyone knows about Mi. Therefore, I choose to believe that Mi Tu will not have loopholes in security issues. However, security is still the primary concern of everyone and small families. We hope that it can attract everyone's attention and strengthen information security to ensure the happiness and stability of every family.

Worry 1: radiation.

Children's telephone watches, that is, children's mobile phones covered with watch skins, generate various radiation in the communication network, which will hurt children's bodies to some extent. Is it really suitable for children's long-term use. Is using a children's phone watch the same as equipping a child with a mobile phone?

Worry 2: screen display.

rice There is no screen display when the rabbit is asleep or turned off. It is very inconvenient to determine whether it has been turned on by trying to turn on or off. If the hardware switch can be added, the switch of the watch can be set through the ON/OFF key, which is more convenient for children to operate.

Worry three: electricity.

Mi Tu can't check the remaining power. My son often keeps pressing the power on button when the power is low, and the watch automatically shuts down after displaying the power on screen. The children can't judge the power state of the watch, which is also a hard injury. If you can display the power on the top right of the screen like a mobile phone, it will be clearer.
