[Preface]

Children's safety concerns parents' most sensitive nerves, and children's loss has also become a sharp social problem. Therefore, children's smart watches that can make phone calls and prevent loss have emerged and become popular rapidly, gaining the favor of parents and children. However, at a time when children's smart watches are becoming more and more popular, the survey report of CCTV Focus Interview recently poured cold water on the industry. In the program, Focus Interview quoted a report from the network security feedback agency that there are security loopholes in children's smart watches, which will enable hackers to monitor children in real time and master their walking tracks. The reason is that most traditional enterprises make children's smart watches. They lack the awareness and ability to resist hacker attacks, so there may be security loopholes. So is there a phone watch that parents can rest assured and wear safely? Today, the author brings you 360 Children's Guard Smart Watch 3 experience.

Appearance

360 Children's Guard Smart Watch 3 is packaged in a small basket style gift box with a transparent window top cover. The appearance of the watch host can be seen directly from the outside. The function introduction of the product is surrounded by cartoon patterns around the box, which will attract children's attention at the first time. The only disadvantage is that the sealing strip in the middle seam of the packing box will leave an offset print that is difficult to remove after being removed, affecting the appearance.

On the bottom of the packaging box is printed the function introduction, barcode, QR code and product related information of 360 Children's Guard Smart Watch 3.

The packing box is also equipped with a strap, which is the same material as the watch strap. It looks like a small gift box.

In addition to watches and chargers, there are screwdrivers, instructions and certificates in the packaging box.

360 Children's Guard Smart Watch 3 currently has two colors to choose from: pink and blue. The author tried the blue model this time. The main body color is blue with a white middle frame, making the watch both eye-catching and cute, which is very suitable for boys to wear. The watch uses a square dial, which is similar to the design of Apple Watch, but is larger and thicker than Apple Watch. It feels that children wear it a little too large.

The small round hole at the bottom of the watch screen is a microphone, the left side of the watch body is an eight hole speaker, and the right side has two buttons. All functions of the watch are completed through these two buttons.

The watch screen is a 128 * 128 resolution OLED health eye protection screen, which can clearly see the information displayed by the watch even in the sun.

The watch strap is made of food grade silicone rubber, making it more comfortable and safe to wear. The needle buckle watchband design can be adjusted for children of different ages to wear. The watch strap is cartoon shaped and can be replaced. It has been launched at present Prince Princess, Little Bear, Little Rabbit, Changjiang No. 7, Plants vs Zombies and other versions are more lively, interesting and less monotonous than solid color watchbands.

The back is fixed with the upper part by four screws, and the strap and the back shell are designed as a whole.

The watch adopts the current mainstream magnetic direct connection charging mode, which is safe, waterproof and easy to operate. The disadvantage is that it must be charged through the special charging line configured by the factory. At present, the charging interfaces of phones and watches on the market are independent, and there is no universal charging interface like MicroUSB corresponding to Android phones.

The watch uses the MicroSIM card, which only supports the GSM network of China Mobile and China Unicom, but does not support the telecom card for the time being. When installing the SIM card, you must first loosen the four fixing screws, which can be removed through the screwdriver provided in the accessories. This can not only seal and waterproof, but also prevent children from accidentally opening the hand case, which causes the watch to fail and cannot be contacted.

The watch is matched with 520mAh lithium Polymer battery, safe and durable. It takes 2-3 hours to fully charge, and it can last 3-4 days in normal use.

3、 Electronic fence

Parents can set a safe area within a certain range. When a child enters or leaves the safe area set by the parents, the watch will automatically send a reminder message to the parents, so that parents can always know whether the child is within the safe range. During the actual test, the error of the safety area is about 50 meters.

4、 One click for help

When children encounter danger or emergency, they can send out a distress message with one button. Long press the upper key on the right side of the dial for a few seconds, the SOS distress message will be sent and the ten second recording will be automatically recorded. The mobile phone APP will prompt the location information and recording of the child's distress in about two seconds, so that parents can know the child's problem at the first time and act quickly.

　　 5、 Prevent dispersion

Bluetooth anti stray Bluetooth 4.0 based on watches is connected to mobile phone Bluetooth, and there is an invisible rope between the two. Once the connection between the watch and mobile phone Bluetooth is disconnected beyond the range, an alarm message will be received on the mobile phone, reminding parents that the child has exceeded the safety distance from themselves and needs to be alert for stray. At this time, the child can be quickly found, Prevent loss of contact due to wandering time.

　　 6、 Sports record

The watch is equipped with an acceleration sensor, which can record children's daily walking steps and amount of exercise.
