I remember when I was young, I often ran out with a group of friends to go wild, and sometimes I didn't go home all night. At that time, there was no mobile phone. Mom and Dad had to go door to door. When they found it, they dragged them home without saying anything, and they could not help beating them. At that time, they thought that their parents were making a big deal out of a molehill. They just went out to play for a long time. Is it necessary to beat them? I didn't really feel my parents' anxiety and love until I became a father several years ago. It used to be good, the people were simple, there were not so many traffickers who abducted and sold children, and they went out to play. They were all small partners, and the safety factor was much higher than today. Now, every day in the news and WeChat friends circle, we can see where children are missing and where a large number of human traffickers have come and gone. It's scary to see. I really feel that I need to tie my baby doll to my body. The child was fine before he was three years old, but he would never run around. After he was three years old, he was curious about everything and ran without a trace. Now it's time to go to school again. It's impossible to always stay with you. We can only think of other ways to give our children more security, so that we can be a little relieved.

What we bring today is a telephone watch product dedicated to ensuring the safety of children - Nugget Children's Smart Watch Generation 2. Friends who like watching variety shows should be familiar with Bukua. In the early days of Hunan Satellite TV's highly rated "Where's Dad?", several star children wore Bukua smart watches. At that time, it was a first generation product, but now it is a second generation after upgrading and improvement. At present, the problem of children's safety is getting more and more serious. One child affects the nerves of two people. So many manufacturers have also targeted the market of children's safety and have launched a variety of children's safety watches. But for our parents, what kind of safety watch do we need and what functions do we need? Today I will talk about my personal views, At the same time, let's also see if the second generation of Nugua children's smart watch meets my requirements. Let's first take a look at its official parameters:

The second generation of Bugua children's smart watch is packed in a colorful iron box. It looks very cute and should attract children's attention.

The second generation of Bugua children's smart watch's accessories are relatively simple. In addition to paper items such as manuals and warranty cards, there are only watches and a set of wireless chargers left.

This Bugwa children's smart watch of the second generation has a very cute appearance. The white body, black dial, orange ears and buttons are more cartoon than ordinary children's watches on the market. The two small ears also flash colored lights according to the situation, and also support voice time reporting. I think these should be more acceptable to children, It must be something that does not meet the children's aesthetic standards. Maybe they will not wear it!

Because it is a daily companion for children, the second generation of Bugua children's smart watches have chosen food grade environmental protection materials that are absolutely non-toxic and harmless in the materials of the whole machine. The watchband has chosen liquid silica gel that is the same material as the baby pacifier, which is softer and more elastic. The watch is very comfortable to wear, and Xuanbao is reluctant to take it off. However, this material also has its disadvantages, that is, it is easy to attract dust, and it is not easy to clean up when it is dirty. The two buttons on the left side of the watch are function keys. The upper button can send SOS distress signal to the bound mobile phone APP by pressing for two seconds. The lower button is responsible for the power on/off function and return function. See the instructions for details.

Because it is a phone watch, the phone card must be essential. The second generation of Nugua children's smart watch supports the numbers of China Mobile and China Unicom, but not China Telecom. I wonder if it will support China Unicom in the future. The mobile phone card only supports Micro SIM card, so you may face the situation of cutting the card or using the card holder. However, if you change your 4G card, you will save a lot of trouble. Here, I would like to make my first suggestion. The card slot cover of the watch is difficult to buckle, and it must be pried with other things, but it is easy to pry out a notch. In addition, the mobile phone card is OK when inserted, but it is troublesome to take it out, because it is concave, so it cannot be taken out by hand (I don't know if the nail length will be better), Anyway, I went to someone's home and found a pair of tweezers to get it out. I suggest you give me something to pick up the card!

At the bottom right of the watch is the microphone of the watch, and at the top is the loudspeaker of the watch. The external sound of the watch is not very loud, but as long as the environment is not very noisy, it is enough. Because the voice communication technology at the same level of Apple watch is used, the voice quality is good, very clear, and there is little noise.

The second generation of Bugua children's smart watch adopts a low power consumption MT2502 main chip, equipped with a 480 mA battery, which theoretically supports a standby time of up to 72 hours. The standby time mainly depends on your use frequency. The dial is equipped with a 2.5D 0.66 inch touch screen with a resolution of 64 * 48 pixels and supports full touch control. However, in the current market, where color screens are dominant and large screens are dominant, the second generation of hardware and melon screens are really shabby.

Hardware Generation 2 supports gravity sensing. When children lift their hands, the watch screen will automatically light up the display time, and then enter the off screen standby mode after a few seconds.

We also know that since childhood, parents have told us not to play with fire or touch electricity. These are dangerous things for children. But as children's watches, they have a strong need to complete the charging work themselves, so Hardware The 2nd generation also took this into consideration, especially abandoning conventional chargers, and adopting wireless charging technology of the same level as Apple Watch. It can be charged quickly and safely with just a gentle release. The red light of the charger is on during charging, and the green light is on after charging. The whole charging process takes about 3 hours.

Hardware The main interface of the second-generation watch is divided into five parts, namely, device information, calling, date and time, family circle and finding friends. Each functional interface can be used to select the secondary menu by touch. The function of finding friends requires two or more devices together, which is not practical for users with only one watch.

If you want to establish a connection between a watch and a mobile phone, of course, you should first bind the device. We should first download the app software that matches the watch Mango Home, which can be accessed through the software market or scanned by the QR code on the manual. After installation, open the software and add Hardware Watch: click on the information interface of the watch to display the QR code, which can be added by APP scanning. Note that the watch can only be added when the SIM card is inserted.

In watch management, for the safety of children, as well as for the sake of children not to make random calls and increase unprovoked phone charges, we can set a family number for the watch. In this way, the watch can only dial the family number you set. Other calls cannot be made. If the "Allow calls from non family numbers" function is not enabled, other numbers cannot be called in, This ensures the safety of children to a certain extent.

In addition to the family number, we can also set up a family circle. You can bring your grandparents, parents and grandparents in, so that you can have family gatherings. Anything can be said in the circle. All the family members in the circle can hear it. Anyone who wants to talk to the baby can send voice to the watch.

As a children's safety watch, I don't know which parameter you are most concerned about. Anyway, I am most concerned about its positioning accuracy, which is the top priority of children's safety watch. Even if its other functions are well done and its positioning is inaccurate, it can only become a failed security product. As long as the positioning is accurate, the additional functions are not perfect, but they are qualified. Think about it. If the child is lost or taken away by a stranger, and the location is accurate, you can find the child quickly. On the other hand, if the positions can differ by thousands of meters, this watch is not helping, but helping. So let's take a look at the positioning ability of Nugua children's smart watch generation 2. Officially, Hardware The second generation adopts the multiple positioning technology of GPS+BDS+GLONASS+AGPS+WIFI+base station, and the minimum positioning error is less than 10 meters. So what's the actual performance? I found several different points in the city to carry out field tests. The vast majority of WIFI positioning errors are about 10 meters, while the positioning of the base station is not necessarily. The less 10 meters, the more 50 meters. Of course, because the accuracy of the map itself is different, the judgment method is mostly based on feeling. In addition, the positions shown by mobile phones and watches on the map often have obvious deviations, but the test results are basically satisfactory.

I thought that the watch supports GPS positioning, so it should have a GPS module, and it should still be able to locate accurately without installing a SIM card. But through the test, if the watch unplugs the SIM card, it cannot update the position.

Like this test result, the correct location should be where the phone is, but the watch ran across the road, with a straight distance of nearly 50 meters. Although the positioning is not as accurate as I expected, it is still acceptable, which is much better than the two positioning watches I have used before.

The second generation of Bugua children's smart watch has the SOS distress and monitoring function. Pressing the upper function key for two seconds will send a distress command to the bound mobile phone APP. At this time, we can conduct voice monitoring of the watch through the real-time listening function, that is, the APP will send a command to the watch. The watch does not respond to any response on the surface, but it has automatically sent a callback to the mobile phone, You can monitor after connecting with your mobile phone.

We can also set entry and exit reminders according to the places where children often go, such as school and home, and set arrival and departure reminders, so that when we go to work, we can easily know whether children arrive at school and go home safely. Event reminders are equivalent to small alarm clocks, which are used for timing reminders of some things.

Hardware The positioning of Generation 2 is divided into power saving, normal and safe modes. The difference is that the positioning refresh frequency is different. We can set it according to the real-time situation, which is also the most important factor affecting the endurance of the watch. Through APP, we can also remotely shut down and restart the watch.


When we locate the child and need to find it, APP can quickly call the navigation function to find her as soon as possible.



At the end of the article, I would like to express my personal views and some suggestions for improvement:
1. Although this is a telephone watch, it is not useless without a SIM card! Can't talk, can't make voice, but at least can locate it!
2. I tested the use of the watch's network traffic. Although it was not much, my baby kept talking with the watch. I felt that the 30M traffic of 5 yuan a month was very stressful. It is suggested that you can provide some directional free traffic to your watch like some smart devices.
3. I was thinking Hardware Is it possible to provide a real-time trend track map, so that in some cases it will be safer, and we can know in real time whether the child is on the right path.
4、 Hardware In the future, could you consider installing a camera so that parents can check the situation of their children at any time and ensure safety.
5. The black and white screen is still a bit too rustic. It is recommended to upgrade it to a color screen!
6. Bluetooth anti loss and safety fence are the basic functions of children's safety watch, why not Hardware The second generation didn't see it?
7. According to the official website, Hardware I personally think it is necessary to add the function of telling stories and singing children's songs in the future. The battery is not enough and the traffic is very small. It is a waste to add such flashy functions.
8. It is suggested to add activity track query to make the children's whereabouts clear at a glance.
