Hot summer weather, many people know to prevent sunstroke, but in fact it is relatively more important in the summer cold weather.
Advances in science and technology have made people largely avoid high temperature damage. There are air-conditioners in homes, schools, work units, various public places, and transportation facilities. The most inconvenient ones are electric fans. Therefore, the time for us to really come into contact with high temperatures becomes shorter, but many diseases are caused by excessive greediness. These cold-induced diseases are more common in the respiratory system (cold, cough), digestive system (abdominal pain, diarrhea) and motor system (joint pain).
How can we prevent the cold in summer? Traditional Chinese medicine also has a traditional method of diet and health care, which is called "eat winter radish and summer ginger." The main purpose of “summer eating ginger†is to prevent cold in summer.
When is the best time to eat ginger? The answer is: morning! The temperature is still high when we fall asleep at night, so we often go to bed with air conditioning, electric fans, and even don’t want to cover a thin quilt. There are also people who like to sleep in the open, and when the temperature falls at night, it’s hard to avoid getting cold. Then, after eating in the morning and eating a small amount of ginger, you can sweat a bit and start cold.
The more important purpose of sweating in the morning is to “heat up†for a day's life. Sweating is the most important physiological function of the human body to cope with heat in the summer. Sweating can cool the heat and discharge metabolic waste. For example, if you blow the night air conditioner, freeze it, don't sweat, and continue to stay indoors, there may be no problem. Once you enter the hot outdoors, the function of sweating will not recover quickly, and your body temperature will rise suddenly. Heat stroke. Qian Yuling

How do WiFi Camera Work ?
Monitoring cameras can also be installed without a network, but some functions cannot be used, such as remote monitoring. In order to make it easier for you to understand the knowledge related to the surveillance camera, I will use popular language to popularize science for you.
1: Camera introduction
Camera is an intelligent device that can capture and record video and monitor the environment in real time. It can not only record video, but also detect moving objects, sound, smoke, and even recognize faces.
The advantages of the camera are very obvious. It can help people better monitor the safety of their homes or offices, and help protect the safety of family members or office staff. In addition, it can also provide real-time video monitoring, provide more security guarantees, and help people better grasp the current security situation.
Among them, "intelligent camera" is a new technology in recent years, which can monitor the environment in real time and conduct intelligent identification. The intelligent camera adopts high-definition camera technology, which can clearly capture the on-site images within the monitoring range and conduct real-time monitoring. It can also analyze the captured pictures to identify the designated person or object, thus realizing intelligent monitoring.
In addition, the smart camera can also support remote monitoring. You can remotely view the real-time image of the camera through your mobile phone or computer, allowing users to view the image of the camera anytime and anywhere, to better protect the security of your home or office.
At present, cameras have been widely used in the security industry to monitor buildings, parks, schools and other places to protect the safety of the people. It can also be used in commercial places to help businesses achieve intelligent management, improve business environment and improve service quality.
2: Working principle of camera
The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
