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.

After the black fungus hanging bags have produced 2-3 flushes of ears, the nutrients inside the bag are usually depleted, and the bags often stop producing due to lack of moisture. At this point, many growers typically discard the bags. However, through practical trials, we found that by using a sand treatment method, it is still possible to produce an additional 3-4 flushes of ears. Here are the specific steps:
First, remove the mycelium bags and soak them in a nutrient solution for one day to allow them to reabsorb water. The nutrient solution consists of: 100 kg of water, 100 g of potassium dihydrogen phosphate, 180 g of magnesium sulfate, 60 g of zinc sulfate, and 100 g of potassium permanganate. This helps replenish essential nutrients and improve the moisture content of the substrate.
Next, prepare a sand bed. Use coarse sand mixed with 1% lime, ensuring the sand has a moisture content of over 50%. The bed should be no wider than 1 meter and as long as needed, depending on available space and materials. Place the soaked bags into this sand bed under a shaded area.
Within four days after the treatment, you can observe a significant number of small ears emerging. Harvesting can begin approximately 10 days later. This method not only extends the production cycle but also significantly improves yield and quality. Compared to traditional methods without this treatment, more than 80% of the income can be increased, while maintaining high-quality mushrooms. This technique proves to be both economically and environmentally beneficial, making full use of previously discarded materials.
