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 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.

Hazardous symptoms After the culture material was contaminated, the colony was white cotton floc in the initial stage and had no fixed shape. Then it gradually turned light green from the center to the edge of the colony, and the colony accumulated and turned dark green. The toxin secreted by the Trichoderma mycelium can inhibit the growth of Pleurotus ostreatus. After the fruiting body was impregnated, a slight brown water-stained lesion appeared on the side of the stipe, and then spread to the cap of the bacterium. When the fruiting body was severe, the entire fruiting body rotted, and the heaviest resulted in rot of the whole bed, and the production was greatly reduced.
Prevention and Control Measures In order to reduce the losses caused by the infestation of bacteria, comprehensive prevention and treatment measures focusing on prevention must be taken in response.
To prevent the invasion of pathogens, we must first use the resistant strains of Pleurotus ostreatus, especially those resistant to Trichoderma viride; Second, we must purify the mushroom house environment to keep the mushroom house at low temperature, low humidity, and low carbon dioxide concentration, so that the air remains fresh and circulating. Third, we must create a living space of 20°C~25°C and a humidity of 60% as much as possible. Fourth, we must do a good job of disinfecting the mushroom house. We can use 10kg of water and add 15g of water to the children or formaldehyde solution to spray and fumigate for one day.
The infected parts can be sprayed and sterilized, and can be sprayed with 5% carbolic acid solution or 75% chlorothalonil wettable powder 1000-1500 times, or with Kejialing 50 grams plus 10 kg water, or Lime 90 grams plus carbendazim 10 grams of water 3 to 4 kilograms, brushing disease department.

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.
Pleurotus ostreatus green Trichoderma should be based on prevention
To do a good job in the production of Pleurotus ostreatus is one of the effective ways for farmers in suburban areas to increase production and income. However, we have also noticed that due to neglect of management, many rural households have not carried out disease prevention well. Mushrooms or fungal bags often cause diseases and cause certain losses. Among them, Trichoderma viride is the most serious.
