Organic vegetables are also called ecological vegetables. They are based on soil. They do not use chemical fertilizers, pesticides, growth regulators, and other chemicals during the planting process. They do not use genetic engineering technology, they use the internal material circulation of the system to supplement the soil, and they use physics. Artificial, agricultural, biological and natural materials and methods to control pests and weeds. The organic vegetables grown are pollution-free, have a good taste, are more nutritious and healthier.
Locusts often occur in growing greenhouse vegetables because the most suitable temperature for the growth and reproduction of aphids is 14-26 degrees Celsius, and the relative humidity is 50-85%. As long as there is proper weather, a large number of locusts can occur. The larvae have strong fertility. A female locust can breed when he is born. Without males, he can become pregnant. He can bred more than 10 generations a year and only 1 generation can take more than 20 days. The locust quickly completed its own evolution and became a "migrating locust." Therefore, in addition to biological and physical control, pest control nets, natural enemies of pests, and biological pesticides are used for pest predation and control, and insect pests are trapped using the inherent phototaxis and odorant properties of pests. You can also use a shed control. When the boring shed is selected, the weather is clear during the day and when the temperature rises, the entire greenhouse is completely closed. After the indoor temperature of the shed rises to 50 degrees, the larvae suffocate for more than ten minutes. When boring, it is necessary to note that locusts will migrate from the upper part of the plant to the lower part of the plant. The temperature from the ground is relatively low. Before the stuffy shed, the plant from the ground shall be tied with a plastic bag. The locust will be glued on the plastic bag and then used. Vinegar spray, the locust died.
The Network CCTV Wireless Security Camera
Compared with wired cameras, wireless security cameras are less invasive to your home, so they are easier and faster to set up. No need to drill through walls or ceilings. Wireless cameras are also more flexible than wired systems because they are not as constrained as wired systems.
The biggest disadvantage of a wireless Camera System is that it is completely dependent on the strength of your Wi-Fi connection. Any interruption or weak signal can mean that you may lose connection to the system, resulting in the loss of the film, which can be critical

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.
The internal circuit of the camera will convert the signal captured by the sensor into a digital signal and send it to the computer. The computer uses these signals to display images, or it can save images to the hard disk drive.
If the camera is not connected to the network, it will not be able to achieve real-time monitoring, but the camera will still work and save the pictures and videos taken. If we need to view, we can only remove the memory for viewing.
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. Users can view the image of the camera anytime, anywhere, to better protect the security of your home or office.
