What is 4G PTZ WiFi Camera
Camera, also known as computer camera, computer eye and electronic eye, is a video input device, which is widely used in video conference, telemedicine and real-time monitoring. Ordinary people can also talk and communicate with each other through the camera on the network with video and voice. In addition, people can also use it for various popular digital images, video and audio processing.
The 4G intelligent camera, also known as 4G camera and IPC, is mainly used for security video surveillance. Its feature is that the 4G communication module is built into the universal surveillance camera, allowing the camera to be directly connected to the network through the base stations of the three operators, breaking the limitations of the original deployment of network cables or WIFI connection, so as to achieve the purpose of remote monitoring.

1. The conditions of the pond are as follows: ample water sources, fresh water without pollution, convenient irrigation and drainage ponds, with an area of ​​3 to 10 mu, and it is better not to select ageing ponds with thick silt. Each pond is equipped with an aerator of 1.5 kW to 3.0 kW. Lime drying and clear pond disinfection are used to kill the enemy pests and pathogens. Water injection is about 1.5 meters.
2. Fish breeding ponds The main breeding stock for catfish is 20 to 50 grams/tail fish species ranging from 3,000 to 4,500 fish per acre, and 200 ton/acre of white flowers (size 7 to 9 cm).
The stock of polyculture of pond polyculture stingray is generally 300 to 500 tails per acre (specification 4 cm to 5 cm). According to the stocking situation of other fish and the breeding technique level, the stocking amount can be appropriately increased.
3, feed production Because the diet of yellow catfish is omnivorous partial carnivorous fish, while feeding artificial compound feed at the same time, if there are conditions, it should also assist feeding fish, animal viscera and other animal feed to supplement the stingray The need for animal protein. The protein content of artificial compound feed should not be lower than 38% to 40%. Formula: fishmeal 4%, imported meat and bone meal 10%, blood meal 5%, soybean meal 20%, wheat bran 20%, premix 5%.
4. The daily management adheres to the three times of early, middle and late patrols, carefully observe the fish activities, feeding and growth, and find problems in a timely manner; often inject new water to prevent water quality from deterioration, and prevent the occurrence of floating fish and fish heads. It is best to inject fresh water 20 cm to 30 cm every 10 days and open the aerator in rainy days. Lime was applied once every two weeks or so, and the amount was 15 kg to 25 kg/mu.
5, fish disease prevention and treatment of yellow snapper disease resistance, disease, but poor feeding and management can also cause disease, resulting in loss. After the fry is put in the pond, fish ponds are sprayed and disinfected, and antibiotics and Chinese herbal medicines are regularly added to the processed feed for prevention of fish diseases.
At present, the functions of smart cameras mainly include video monitoring, voice dialogue, security alarm and video review.
Video surveillance
Video surveillance is the core and basic function. The current intelligence is that the mainstream resolution of cameras is 1080P HD, which requires a high level of network. Most home cameras transmit data through WiFi, which is convenient to move. Some stores also install such cameras, which are mainly used to monitor the main points such as the cash register. This kind of camera that does not need to move can use the network cable, and the signal will be more stable.
Voice conversation
Most cameras on the market are equipped with the function of voice conversation. Users can directly have voice conversations with their families through the APP. Of course, although many devices on the market support this function, noise elimination, uneven echo and other situations still occur frequently and need to be improved continuously.
Security alarm
The security alarm function is mainly used to record vibration, special noise and other vibrations, and alarm through APP.
Video review
At present, smart cameras on the market all provide the function of video review, but most of them only provide the function of alarm review, that is, the video recorded after the alarm occurs can be reviewed, and the rest of the time can not be viewed, and it is a paid function. Few manufacturers can provide uninterrupted video retrieval function. The reason is simple: the cost of video storage server is too high. Video belongs to large flow files. If you want to achieve uninterrupted recording, storage and review, the cost will be many times or even dozens of times higher.
4G intelligent camera
The deployment of wired network is troublesome or the coverage of WIFI is limited. For example, security monitoring of mature commercial offices or new indoor and outdoor blank areas in residential areas, video monitoring is required for outdoor construction sites, and 4G intelligent cameras are required for the deployment of wired network is troublesome and scattered.
Sturgeon breeding techniques
